National Eye Health Week

Despite the fact that over half of all blindness and visual impairment could be prevented, with early diagnosis, only 66% of UK adults have taken an eye test in the past 10 years, according to the RNIB.

So the RNIB are running National Eye Health Week, to raise awareness of how to look after your vision and avoid sight loss.

As well as possibly preventing blindness, regular eye examinations can also lead to the discovery of the early stages of other illnesses, such as diabetes, so can be useful for general all-round well being, not just seeing if you need glasses.

The RNIB point out a number of simple ways of avoiding sight loss, such as stopping smoking, wearing sunglasses, wearing safety goggles when doing DIY and eating a balanced diet, all of which could reduce the figure of 100 people in the UK losing their sight every day.

Sight loss can happen to anyone so looking after your eyes is very important and something most people don’t think about until it’s too late.

London 2012 Paralympics : Guide to sports for the blind

The London 2012 Paralympics was launched tonight with the opening ceremony.  After the huge success of the Olympics this is the chance for the biggest Paralympics ever to shine.  To the athletes their disability is almost incidental: it;s not about their disability but about their ABILTY, what they CAN do.
This is a guide to the main sports to be competed by blind and visually impaired athletes.  There may be some level of sight loss in other sports but these are the sports where visual impairment categorizes them for these events:

Athletics

Athletes must trust guides that shouting or giving other acoustic instructions as they run, throw or jump.  Some athlet6es have sighted guides that run with them whilst others are visually impaired with limited vision.  Each different level of impairment runs/throws.jumps in different categories.

Cycling

Visually impaired cyclists ride tandem with a sighted pilot up front steering them around the track.

Football – five-a-side

Four outfield players - wearing blindfolds to give everyone the same level of visual impairment - and a sighted goalkeeper compete two halves of 25 minutes.  The ball has ball bearings inside, so players can hear where the balls is and the pitch is surround by acoustic boards so sounds reflect – the crowd is asked to be quiet during play.

Goalball

Two teams of three blindfolded players play two halves of 12 minutes.  Teams must get a medicine ball full of bells beyond the opposing team to score.  The defending team uses any part of their body to prevent the attack.

Judo

In the Paralympics Judo is reserved purely for the visually impaired.  Although graded on levels of visual impairment competitors fight in weight categories, rather than disability level.

Rowingg

Skulls are adapted with additional stabilising "pontoons", buoyancy devices to aid balance.

Swimming

A number of events based on severity of disability. For the visually impaired a taper is placed across each lane which prompts swimmers of the approach of the wall.

My guide dog and I

I’ve had my guide dog for a couple of months now and getting him was one of the best decisions I ever made.

Jet is a wonderful black labrador, two years old at the end of next month. Not only is he good at his job, enjoying his work, he also has a lovely temperament, is very social and is absolutely no trouble whatsoever. He fits into my life perfectly. This is testament to the brilliant work by the guide dogs Association, their trainers and their puppy walkers.

Guide dogs is a wonderful organisation. The dedication, training, advice and help that the charity gives is superb and can't be faulted.

The process started with a visit from a member of the team who came to my home to discuss whether getting a dog would be right for me. We talked about my condition, my lifestyle and how the guide dog might benefit my life. Once the decision was taken that a dog would be good for me, it was arranged that I would have some test walks to see what kind of dog would suit.

The first walk was around my local area within member of the team holding a harness, no dog involved. This was test my mobility, how I got around with my white cane, speed etc. This was followed a few weeks later with another walk, this time with the kind of dog they thought would suit me. All the time I was being assessed so they can actually with a suitable dog.

Then I was put on the waiting list. As I had not specified the type, breed or sex of dog the process of finding the right dog from me would probably be quicker. Some people are quite particular about the kind of dog they want. The charity has a set of criteria so people are matched to the right dog. People have different needs, such as how much exercise the dog will need, it's size overspeed it walks for example.

Once they found an animal that they thought was right for me it was time for my training. Training can take place residentially at a number of hotels around the country or within the home. As I am quite active and used to dogs, my training was from home. So for three weeks Jet moved in and everyday we went out with a trainer learning all the commands, techniques and everything I needed to know about working with a guide dog. A health visitor also came to see me to talk about the care and welfare for jet.

Once been given a lot of information and qualifying, I was handed over the reins and for a nominal fee of 50p, Jet became mine. The backup support by the organisation is brilliant, any problems I have with jet, they are only at the end of the phone. Regular visits to see how he is getting along mean he will always be in good condition. As well as his training, vets bills and after-care, they even offered to pay for his food, which I declined as they had done so much already.

Guide dog ownership is wonderful. It has made so much difference getting around. It has helped my confidence moving around in a visual world with sight loss. As well as a working dog he's also become a great buddy. He's got a great temperament, he so well-behaved (most of the time!) And makes me laugh every day. Guide dogs answer everybody but personally it's been fantastic.

Voice recognition software – using Dragon NaturallySpeaking 11.5

I haven't written anything for a while. There are number of reasons (or excuses), one of them is that my vision has been deteriorating stop. To help me continue using the computer I have purchased some voice recognition software.

Dragon NaturallySpeaking uses voice recognition to type in what I say into a microphone) VGA rather than using the keyboard. It wasn't long ago that voice recognition software was a hit and miss affair. But as you can see from this blog post, which I am dictating not typing, the technology has improved immeasurably.

This is so much easier than touch typing. I can use natural speech patterns and talk quite normally and the program understands and inputs what I want. In the past this type of software  required you to speak each word in a robotic manner but now you can just speak that this it normally, albeit adding punctuation as you go.

It is early days of me using Dragon NaturallySpeaking and the software learns your speech patterns and pronunciation the more you use it. I will come back to the subject after I've been using it for a while but so far I'm extremely impressed.

My biggest criticism of the Dragon NaturallySpeaking is, that for a program so obviously useful to the blind and visually impaired community, the menus, dialogue boxes, and activation are all very small, and it would probably need a sighted person to help initial setup. Many other programs these days, designed for people with sight problems, have setups with speech, that talk you through the installation. It would have been nice for Dragon to have included this.

Still, I can see how useful this piece of software could be to people with sight loss.

Katie: The Science of Seeing Again - Channel 4 Tues 7 Feb

With all the recent news about stem cell research into restoring vision in some sight conditions, (includng this story on VWS), Channel 4 are showing a programme tomorrow night following Katier Piper, a model who lost the sight in her left eye after an acid attack.  She has injections of embryonic stem cells into her eye,  which could potential restore her sight.  The programme also deals with the ethics issues in the procedure, which some think is morally wrong as it uses cells from human embryos.

The programme airs tomorrow at 9pm on Channel 4 and will be available on 4oD online a day later.

Accessibility software: programs to help the visually impaired and blind to use computers

“My computer is, to communication, what my guide dog is to mobility”
As part of my job I visit people with little or no sight and help them make their computers more accessible
The quote above is from one of my clients and sums up how computers can be so useful to people who have difficulty seeing.  Computers and the internet are ubiquitous these days so it is imperative that the blind are not left out. 
There are many programs that can help by manipulating what’s on the computer screen (such as changing contrast or enlarging it) or by speaking what’s being displayed. 
They use different methods of accessing and interacting with the computer, for those who may find the mouse, cursor and even the keyboard, difficult or impossible, with their level of vision.
The next few posts are a reproduction of information we give out to clients in four categories:
  • Screen magnifiers
  • Screen readers
  • Combination magnifiers/readers
  • Other assistive software
These are just a few examples of the many programs out there.  The prices shown are approximate, October 2011. All prices are excluding VAT. Those registered as sight impaired or severely sight impaired will not have to pay VAT on these products. Links to trial software that can be downloaded from the internet mean you can test the different products before you buy, to see if they suit your needs.

Assistive Technology Software 1: Speech Software

Speech output or screen reading software provides access to on screen information through synthetic speech. The user navigates the computer via the keyboard and the current focus is announced. By its nature, screen readers give a narrow view of what is on the screen, for example a sighted user may glance at the clock to get the time; a screen reader user would need to know the keystroke to get that information. To fully utilise a screen reader therefore, the user must learn a wide range of operating system and screen reader specific keystrokes.
In general, you get what you pay for with screen readers. However, whether a home user needs the extensibility of a high end screen reader such as JAWS should be questioned when free alternatives exist.

Disabled Go: is the place you’re going accessible?

Being disabled can make a person think twice before going anywhere.  Is it going to be accessible?  Am I going to be able to enjoy and take advantage of the facilities?  Is it worth me bothering?

Having this kind of information before visiting somewhere can be invaluable to help prepare you and avoid disappointment.  It can be all too easy to put off a trip because you’re unaware if it will be worth going if your disability is going to be a major disadvantage or you’re nervous how you’ll cope.

The web site Disabiled Go can help.  It is a online resource listing detailed information on the access to a wide range of places such as hotels, restaurants, education establishments, tourist attractions, libraries, hospitals, local services and more.  All venues are personally visited by the Disabled Go surveying team and lists information from facilities for the disabled to details of toilet facilities, or even the surface of the car parks.

Using an easy interface, the site covers all aspects of things that could be a problem for people with all kinds of disabilities and could help in making decisions on whether it’s worth visiting somewhere or even deciding to go somewhere you thought wouldn’t have been an option before.


Disability Go also lists jobs, has news of events and disability issues as well as a discussion forum.

The site doesn't cover everywhere but is growing and constantly being added to.

Action for Blind People on The Secret Millionaire

Some of the ways people can suffer from loss was highlighted on last week’s Secret Millionaire programme on Channel 4.

The show takes takes a millionaire from their luxury lifestyle  and sends them out undercover to find people making a difference  and which the millionaire can help in return with a donation.  This episode followed Edward Douglas-Miller, who tragically lost a daughter just after birth and had sight problems which he feared could lead to losing his sight.

One person was Bernie Reddington, who works in the same role as me at Action for Blind People in Norwich (Assistive Technology Coordinator).  Having lost her sight 17 years ago and two of her children inheriting the condition she has, she showed how she copes being totally blind and helping others in similar situations.

The programme also met a woman running a charity that helps bereaved parents and a man with motor neurones disease.  An emotional watch, available on Channel 4’s catch up web site 4oD:

Tablet computers used as Braille keyboards

Researchers at New Mexico University have developed a system that uses tablet computers, like the Apple iPad, as Braille keyboards.

Touchscreen tablets can present a problem for blind and visually impaired people when the normal on-screen keyboards are not tactile and can’t be seen. 

Tablets like the iPaad use speech software that feed back vocally what is under the users finger, meaning that you have to slide your finger around the screen until you find the right key.  Rather than the users fingers having to find the keys the research group has developed a system where the device works out where the users fingers are.  The combination of fingers determines the letter typed, in the same way a Braille typewriter would.

Though not yet commercially available the group hope to release the system which could be portable and help speed up typing, note taking and numerous other applications.

Elderly who take a daily Aspirin could be twice as likely to develop age related sight loss

A European study has found that pensioners who take an Aspirin  everyday increase the risk of developing late stage age related Macular Degeneration (MD).  People who took the painkiller were shown to be twice as likely to suffer from MD as those who didn’t.  MD is the leading form of vision loss for the over 60’s

Many over 65’s with, or at risk of, heart disease take Asprin as an anti-coagulant to thin the blood but research by Dr Paulus de Jong at the Netherlands Institute for Neuroscience and Academic Medical Centre suggests that it could be unwise to recommend taking Aspirin for people showing signs of the eye condition.

The study doesn’t show why the drug exacerbates the eye condition, which examined the lifestyles of nearly 4,700 patients. It showed that roughly 2 out of every 100 people who didn’t take Aspirin developed wet form MD, the more severe form of the eye condition, whilst the figures jumped to about 4 per 100 with the patients who took the drug everyday.

It’s not thought that the drug causes MD, as it does not seem to effect early stage MD.  It seems only wet, not the more common dry form MD, is affected.

However, Dr Jong told the Reuters news agency “For people with cardiovascular disease who take aspirin to prevent the condition from worsening, the benefits of the drug outweigh the risks to visual health… A healthy eye with full visual capacities is of no use in a dead body.”

Stem cell research could lead to the reversal of sight loss

It was announced last week that the first ever European trails using embryonic stem cells has been approved by regulators.  Moorfields Eye Hospital in London will start the trails on 12 patients with  Stargardts Disease, a form of macular degeneration, which causes sight loss at an early age.

The initial trails will take the form of injecting tiny amounts of retinal stem cells into the eye, initially to assess the safety of the procedure.  If this is successful it is hoped that higher doses will help regenerate the damaged retina and restore eyesight, effectively “curing” the disease.

In America, trails in safety of stem cell therapy for people with spinal injuries is already taking place.  Bone marrow transplants using stem cells and the growing of a new windpipe from the patient’s own stem cells have been successful in recent years.

Macular Degeneration (MD) is one of the biggest causes of sight loss (47% in the UK).  It’s thought that if everyone lived long enough, everyone would eventually develop some form of MD and become blind.  Stem cells can regenerate all forms of human tissue, so it is hoped that this treatment could help other forms of degenerative sight loss.

There is some controversy over the use of stem cells in medicine.  It is opposed by Pro-Life groups because the embryo is destroyed when the cells are harvested.

Best of British - Channel 4 documentary follows 2012 Paralympics hopefuls

Tonight on Channel 4 a new three part documentary starts. "Best of British" follows hopefuls for the London 2012 Paralympics GB team.  The first programme follows three blind footballers, fighting to make the GB squad.

"The first film in the series follows Dave Clarke, Robin Wiliams and Owen Bainbridge from the British Blind Football squad.
As well as following the highs and lows of team selection and the squad's performance, the film also meets the players' families.
What's it like for the players to have sighted family members and children, and what is it like for those families to have blind sons, brothers and fathers?"
Owen Bainbridge is a good friend of mine and was one of my lodge mates during my time at the Royal National College for the Blind.  As the camera crew followed him in his daily life, they also interviewed me.  So you might alsao see me on the programme.  Fame at last!

The Blind Traveller

Sometimes the stories you hear in the news about blind people doing extraordinary things (such as running marathons, breaking blind land speed records or climbing mountains) can be intimidating when you’re experiencing sight loss.  Some of the things I hear about blind people doing, I wouldn’t have even attempted fully sighted! 

Not everyone is an adrenalin junky or wants to be a record breaker, or whatever, but just wants to live as normal a life as everyone else.  Sometimes their disability can make that seem like an heroic effort in itself and going into your shell is so easy.
However, these stories can also help people realise that a disability doesn’t have to prevent people from achieving their goals or even just doing the things they love.
As someone still getting used to getting around with deteriorating eyesight the story of “Tony the Traveller” is inspiring.

I met Tony Giles this week.  He was born with a genetic disease the eventually robbed him of all sight and has only 20% hearing without his hearing aids.  He also had a kidney transplant in 2008.   He was telling me how he’d not long returned from a solo trip to Argentina and Antarctica.  He has travelled the globe, visiting all 50 U.S. and all 10 Canadian states, crossed the Artic Circle and bungee jumped in New Zealand.

With the help of local guides and fellow travellers he befriends he has visited more countries, experienced more exotic locations and tasted more weird and wonderful local cuisines than most people will in a lifetime.  Tony is 33.

Tony has written a number of books, in the form of his travel diaries, also available in different accessible formats.  You can find out a lot more on his web site "Tony the Traveller" .

For anyone going through the life changing effects of losing their sight, stories like Tony’s can highlight the fact that things they may have thought would become impossible to do, are still out there to experience, even if it might just take a little more thought and effort in how to achieve them.

Quote from the Tony the Traveller web site about his book “Seeing the World My Way”:
“Seeing the World My Way follows Tony Giles’ journey of hedonism and thrill-seeking adventure as he travels across North America, Asia and Australasia. Full of drama, danger and discovery, this fascinating travel biography is a young blind man’s view of the world as he sets out to achieve his dream, dealing with disability whilst living life to the limit.
From bungee jumping in New Zealand to booze filled nights out in New Orleans, Seeing the World My Way is a no-holds-barred account that is certainly not for the faint hearted. Travel the world in a whole new way with Tony Giles’ frank, honest and exhilarating romp through one adrenaline-fuelled experience after another.”

"Let's make the web more accessible" - RNIB campaign

Online services on the internet can be tricky to navigate, even at the best of times.  For people with disabilities that use assisstive technology to access the web they can sometimes be impossible.

There are laws in the UK that mean shops and public places have too be made accessible to disabled people.  Household bills and government  correspondence be made available in various formats, such as braille, audio and large print.  A company wouldn't dream of creating, for example, one of their stores inaccessible to people in wheelchairs, just to follow a trend or incorporate certain design features.  So why is the web no following suit?

The Internet is becoming ubiquitous in everyday life, especially with the advent of mobile access to the world wide web.  Many online services, such as travel web booking sites and online shopping has concentrated to much on the look of their design and interactive content that they haven't taken into account accessibility, or alternative versions for the disabled.

The  RNIB "Online Services Project" in conjunction with "Fix the Web" is challenging the most popular and worst offenders with the aim of making them change their online services available to all.  They are encouraging people to report and sites that have caused people problems when trying to access with screen readers or magnifiction software.  They want to make the web's top 50 online services accessible to the blind and partially sighted.

If you know of an inaccessible web service and would like the RNIB to challenge the company or organisation into creating a more level playing field for all, visit the  RNIB "Online Services Project" page to find out more.

Glastonbury with a white cane

Losing your sight is more than just losing your vision.  You also lose many other aspects of your life and have to cope with and come to terms with changes that don’t cross the mind of people who only focus on the fact that you’re going blind.

I have found that I’ve had to deal with a complete change in who I am.  I used to be a graphic designer, I used to drive a VW Campervan, I used to love all variety of films, I used to be an avid reader, watch a lot of football and play video games.

All of these, if not impossible, are now a lot more difficult.  It’s things like this that define who you, so when you find you can’t do them anymore you lose part of who you are.  You have to hold on to as much as you can and adapt the way you do things.

The first topic of conversation when seeing someone is invariably how my sight is or other vision related topics.  I’m as guilty of it as the next person because it has become the major factor in my life and everything I do.  I’m the severely visually impaired bloke, the blind guy, the one with the dodgy vision.

I was also the one who went to Glastonbury Festival every year and I was determined this wasn’t going to change, just because I’m losing my sight.

Glastonbury Festival
Glastonbury is Europe's largest and longest running Music and Performing Arts festival.  I first attended in 1993 and haven’t missed one since 1999.  It’s something I do, my escape, my annual holiday.  The thought of missing it is upsetting. 

Last year the festival’s final headline act was Stevie Wonder.  He made a speech at the end of his set about how the world should be accessible to all.  It seemed deeply personal and I stood there, not knowing if it was my last festival because of my failing eyesight, with tears in my eyes.  When it came to the tickets for 2011’s event going on sale, all doubts of whether I should go or not went out of the window.  Somehow I would make it.

My friends all said help.  They would get me there and help me round, even though my condition had got worse since last year.

Getting there:
Once I’d secured my ticket I contacted the festival staff about getting a disabled pass.  This meant we’d be able to use the disabled car park, closer to the camping and if I wanted the disabled camping area too.  I decided against the latter, I’d be camping with my large group of friends with the rest of the 170,000 party goers.

With a Disabled Parking sticking in the windscreen of my friends car we were ushered to the disabled car park quickly and efficiently, parked up and in the queue for gates open.  Inevitably for Glastonbury, the heavens opened as we stood waiting to get our wristbands and information and this is where I have my only complaint about the festival’s disabled facilities.  It took forever to get the things we needed to get onto the main site.  We were queued outside in the rain for nearly three hours, with no cover.  People with various disabilities, including in wheelchairs, got soaked as the few staff did their best to reduce the queue of maybe 150 people. 

We then had to wait a long time for a minibus to ferry us to disabled camping. At least we hadn’t had to lug all our stuff across the huge main car parks.  It was a good service but did not take into account the numbers of people that were there for the opening of the festival. 

On site facilities:
As well as being given the festival wristband to get into the site, i was given a disabled camping and disabled facilities wristband and a code for the disabled toilets.  I was also given a pass for a carer, who would be able to accompany me when using the facilities, such as the viewing platforms, and this could be transferred to anyone I wanted to take with me.

The facilities at the festival for disabled people were a great help.  Getting around the huge site, which for the rest of the year is a working farm.  Viewing platforms at the main stages meant disabled people could watch the bands from a flat, slightly raised and less crowded position.

Next to each platform and dotted around festival were disabled portaloos.  The toilets at Glastonbiry are infamous and have an (unfair) bad reputation (they’re better than most large festivals). 

Having larger, cleaner and more accessible toilets is a great help as getting through the crowds and then having to queue as a disabled person is a lot more difficult.  Having a small combination lock padlock could have been a bit of a problem for the toilets without attendants but there was always someone with me to help.  The attendants at the viewing platforms were very friendly and helpful, as were almost everyone on site.  On seeing my white cane/wristband everyone was more than willing to give assistance, staff and punters alike.

Getting around:
it certainly helped that I know the massive site well and I was with a good crowd of friends, who were always willing to help (including putting my tent up, thanks guys!).  We made sure we camped near a path, with clear access (i.e. no guy ropes in the way).

Using my white long cane helped in a couple of ways.  It showed people of my disability and people would be happy to make room for me, to the extent that my group of friends started putting me up front when going anywhere because it acted liked the parting of the Red Sea !

Being a farm the ground is very uneven and rocky in places, making it treacherous at the best of times, when it rains it has an added hazard. it the wet slippery mud (and gloopy stickiness as it dries) it’s impossible to swipe the cane as you would on pavement, so where possible I had to tap (or sometimes just hover) the cane.  This made each step on the un-even ground hard work, not knowing whether it would be a dip, a rise or even a rock or other object.  By concentrating and being careful it wasn’t too bad but it was mentally as well as physically tiring and took a lot longer than normal.

It always takes loner than you think to get anywhere at Glastonbury, even more so with a disability.  I missed a lot of things I had wanted to see, mostly because of the time it would have taken to travel between stages.  The festival organisers have helped out a bit with this by having a few paths via the back stage areas between a few of the main arenas.

Overall:
I’m glad I decided to go, whatever my worries were.  I saw some great bands and comedians, friends I hadn’t seen since last year’s festival and the group of friends I always camp and have a great laugh with.

It’s a daunting place to sighted people so it could be overwhelming to someone with vision impairment. 

I missed a lot of the extra things that make the festival so special: the site art and decoration, the circus acts and street performers, the crazy people that go and all the weird and wonderful wackiness.  When going from stage to stage I had to concentrate on where I was going so missed all the stalls and all variety of colourful sights.  But the atmosphere and the brilliant music on offer (U2, Paul Simon, Queens of the Stone Age, Biffi Clyro,  Morrissey, The Kills, The Wombles! etc. etc. etc.!!!) and the invaluable help from Glastonbury Festivals Ltd and some special friends, made it all worthwhile.

And the next one will be my 20 year anniversary ! So I can’t miss that one.

Image to voice text readers for the blind

I was given a demonstration yesterday at Devon in Sight of a brilliant piece of kit. The Optelec ClearReader+, a machine that takes a photo of a text document and in seconds reads it back to you. It is acurate, easy to use and relays the text in a very clear voice.

The unit is about the size of a thin, slightly taller car battery. An arm folds out with the camera on and by placing the document parallel and at a right angle (straight on or sideways) it can read an A4 size below it. I was shown it readin a printed document and a newspaper article. With the newspaper it managed to distinguish between the headline, that spanned four columns in a larger font and the copy's separate columns, very impressive.

How it deals with text on different coloured backgrounds and different typefaces, I don;t know but what I did see was 100% acurate, the potential uses are huge.

The controls are minimal and simple and it has a number of features, such as four languages, four voices, both male and female, the ability to record and portablity, with a claimed battery life of five hours continous use.

However, coming in at just under £2,000, for personal use it price strictive but for use in the workplace, this could be the answer for a lot of people with sight loss needing to read a variety of printed work.

iPhone alternative:
A much cheaper, though not quite as accurate alternative is an app for the iPhone. At on 59p the app "Image to Speech" from GP Imports Inc Software, utilies the iPhone camera to take a snap and interpret anything in the image it believes to be text and reads it back out loud. The results are very hit and miss.  Clear, large, well lit text works best but as a staring point this is a brilliant innovation.

Maybe later updates will improve it's accuracy but currently it is only really useful for reading signage or small amounts of text.

Like many apps that could be of great use to the blind and visually impaired, the developers have missed a trick and made the interface not completely compatible with VoiceOver, so some level of vision is needed (lining up the text in the camera viewfinder is obviously another issue). But apps such as this show the potential of platforms such as the iPhone being a tremendous tool for people with sight loss.

Devon in Sight - charity relaunch

The "Devon in Sight" charity celebrated it's relaunch and rebranding with the official opening of it's refurbished Resource Centre in Topsham, near Exeter. Formally known as Devon County Association for the Blind, it is based in the old Station House next to Topsham Station but covers the whole county, helping people with all forms of sight loss, whatever their age, sex or background.

The ceremony was well attended in the beautiful sunshine and the cutting of the ribbon was announced by the town cryer and performed by "Dad's Army" actor (and Topsham resident) Bill Pertwee. After speeches by Lady Devon and Martin Pallett, Director of Services for Devon in Sight the crowd were treated with refreshments and live music and shown around the new facilities by the friendly, helpful staff.

The Resource Centre is housed in the beautiful Station House, a Grade 2 listed building, which has been modernised inside to be larger and brighter than before, giving space to view assistive technology, useful household gadgets and computer equipment designed to aid those with sight loss. The impressive equipment on show can be tested hands on and advice given by staff in the centre and the charity is developing it's "Volunteer Visiting Service" as well as new centres in Torquay in Plymouth . It's also establishing new social and lesuir opportunities, countywide. They have doubled the times the centre is open each week so customers can visit throughout the day.

The charity is run by fundraising and a membership subscription costs just £12. If you would like to contact Devon in Sight for opening times, advice or to donate contact:
