The trouble with talking books - a heart felt description

On a daily basis I listen to  many people describe how precious their eyesight is. As an optometrist I am interested in establishing a picture of what is important for the person sitting in my consulting room. Reading is a very common pastime. A keen reader myself I can relate to the simple pleasure found in books. Lynley Hood's account of the problems with talking books, and her grief over the loss of reading will resonate with anyone with a love of reading.

Here is her description of what happened;

"On 20 December 2009 I was reading in bed when my left eye went blurry. "Time to put the light out," I thought.  Next morning it was still blurry. I had lost the central vision in my left eye, suddenly and permanently. Then the vision in my right eye began to deteriorate. 

"The cause turned out to be a rare retinal disorder that goes by the acronym azoor (acute zonal occult outer retinopathy). There is no known effective treatment for azoor. The prognosis is uncertain. 

In the weeks following that first episode, I considered my priorities and made a bucket list ("things to do while I can still see to do them"), but in those anxious early days a single desperate thought possessed me: "Gotta read all those books on my bedside table while I still can!" "

Lynley Hood

Award-winning author Lynley Hood is a Dunedin-based scientist, independent scholar and writer. Following her vision loss she has become an advocate and voice for New Zealanders with Visual Impairment. She writes clearly about the shortfall in services for people like herself - read Absence of Vision. Lynley is one of the founding trustees of Vision Impairment Charitable Trust Aoteoroa (VICTA). VICTA describes itself as an energetic new trust working for New Zealanders with uncorrectable vision loss.

Lynley's writing about living with vision loss has included an eloquent description of all her bugbears about talking books. She describes the suggestion that audio books are a substitute for reading print books as an empty platitude.

As both a keen reader and listener to audio books I am taken by her description of all the things she misses now she is no longer able to read print. She describes her grief and her longing to read books. It is sad to hear her describe her loss - I found her description of what she misses in print so eloquent.  She describes the experience of reading books in a way which will connect with all book lovers.

All Lynley's writing gives those of us with good sight a keen awareness of the loss associated with vision impairment. If you are having a tough day read her piece on Becoming Illiterate. It will give you pause for thought and a reason to be grateful.

 

An Optometrist's Thoughts on Vision for Driving

According to a recent proposal by the Ministry of Transport NZ Drivers may soon be renewing their licences online. Convenient and undoubtedly a huge saving, but with the important change that drivers would renew without vision tests. So what does an optometrist think?

This new proposal will still require first time licence holders, and those over the age of 75, to take an eye test. This seems sensible to me. But for the years in between drivers would make a declaration that they are not aware that their vision has deteriorated since their last renewal, or any deterioration is being managed by wearing corrective or contact lenses. 

It is quite common for people to present for an eye examination and be unaware of deficits in their eyesight. Changes occur gradually so can easily go unnoticed. If we accept there should be a standard for eyesight for drivers, then I think it should be checked at regular intervals. Remember the majority of drivers are tested successfully at AA using a vision screening test. This is straight forward, and when carried out by trained AA staff, it is a cost effective way of testing vision across the general population.

Driver licensing is a key element of road safety. To get a licence, we have to prove we know how to drive safely and follow road rules. Good vision is important for safe driving and most other countries similar to ours require a vision check before you get onto the road. This seems fair and reasonable!

What is under review is the need (and benefit) of checking vision every ten years; apparently we in New Zealand are unique in this requirement. Good vision is important for safe driving but requirements for repeated vision testing may be unnecessary? Policies about re-testing vision at licence renewal vary. New Zealand is one of four places in Australasia that requires vision testing at every licence renewal. Many others only have age-related vision testing starting between ages 70 and 80. 

There were two studies to examine the safety benefits of vision testing. In the first study we examined the crash rates of a sample of over 7,400 drivers who failed a vision check at a licensing agent and were then required to wear contacts or glasses while driving. The crash rates of these drivers before and after failing the vision check and being required to wear contacts or glasses were virtually the same. In the second study the crash rates of drivers in the three-year period before they renewed their licences was studied. Again there was no difference between the crash rates of drivers who failed the eyesight test at renewal and those who passed. For more information see Eye Sight Crash Test Study.

 Like all reform we have to weigh up the risks of reducing regulation. I think testing eyesight before we get onto the road is sensible, and re-testing when we renew our licence is a smart idea as well.

Helping Your Child Develop Good Vision Habits - How Behavioural Optometry Works

Vision is more than eyesight – it is how your child interprets, understands and acts upon the information coming in through their eyes. Many children have normal 20/20 eyesight yet struggle in the classroom. This can be due to problems with:
● Eye movements
● Eye teaming
● Eye-hand coordination
● Visual form perception
● Long-sightedness

Visual skills normally improve over time as a child develops. If there are areas where your child is not progressing or school performance is declining, we recommend a full vision assessment with Sally Adams. Sally has completed three specialized Behavioural Optometrist Extension courses. Behavioural Optometry is described as special interest in vision beyond the eyeball. An assessment  with Sally can identify vision problems which can be improved with glasses and Vision Therapy. 

What you can do to help your child develop good vision habits:

● Check your child keeps both eyes the same distance to the page or screen, at a distance at least a forearms distance from their chin for reading, or arms distance for computer screens. 

● Reading or writing is best on a 20 degree slope rather than flat on the desk.

● Encourage your child to look up and refocus in the distance after every page they read, and at regular intervals when using a screen.

● Sit in a balanced upright position, both feet on the floor; this reduces distraction from fatigue and discomfort while doing homework, reading, drawing, using a computer or tablet.

● All students of all ages and abilities work better in short bursts of 10 minutes or less, especially those with vision problems. Make sure your child gets up and moves around, ideally goes outside to play after each 20 - 30 minutes of reading, writing or computer / screen time.

● Encourage your child in sports and outdoor activities. This improves eye-hand co-ordination, spatial and other visual skills as well as improving concentration.

FAQ - Progressive Lenses

You don't have to go far to hear a bad story about how difficult it is to get used to progressive, or graduated lenses.  People might tell you about having to lift your chin, or they have difficulty when you are reversing a car. Yet many people successfully use progressives every day, ourselves included.  Here are some of the FAQs about progressive lenses.

Zones in a progressive lens.

What will I notice when I start to wear my progressives?  You will notice areas of soft focus at the edges of your vision.

Most people will move their head more in the first few days wearing progressive lenses. This quickly becomes more natural as you adjust into the correct position automatically.

We recommend tucking your chin when walking down stairs.

Will I have to lift my chin in order to read with the progressives? Once you are used to your progressives you will look through the correct zones without having to adjust your chin. Looking down will be clear for reading, and when you look into the distance you will be looking through the upper portion of the lens.

How should I use my lenses to help adapting to them?  Ideally you should wear your new progressive lenses every day from the very beginning - morning until evening. Avoid switching back and forth between your new glasses and older prescriptions.

Do I have to wear my progressive lenses all the time?  No. Many people successfully wear their progressives only part time, e.g. at work, or indoors at home. It is useful though to wear new glasses all day for a few days while you are adapting to the new prescription.   

I am aware of blur to the sides? Remember to point your nose at what you want to look at. You will become less aware of the vision at the sides as you use the lenses more.

Should I drive in my new progressives?  To begin with take care when driving. When you are adapting to progressives in the early days it is best not to drive with them - wait until you are confident.
