Why 20/20 Vision Is Not Enough
| |
If you or your child has been told “The eyes are fine – you have 20/20 sight”……well, you may still benefit with Vision Therapy!!

 20/20 simply tests your distance sight at 20 feet (6 metres).
20/20 sight tells you nothing about your eye muscles.
Students today read almost three times the number of textbooks their parents did -- plus they often work at computers.
In today’s schools and offices most of our time is spent reading or or at a computer. For these tasks you need strong eye muscles. Your eyes must have excellent efficiency and endurance for maximum performance in today’s schools and offices.
Intensive near vision tasks can stress the vision system and produce many symptoms and problems. Many children have learning problems.
People who work in offices may spend the whole day in front of computers and suffer eyestrain. The most common complaints of computer users today are vision-related.
When are Eye Muscles used?
When you read a book or work at a computer screen, you need move your eyes inwards and aim both eyes at the page or screen. This is requires the eye muscles to work.
There are three main types of eye muscle function:
1. Convergence - The eyes turn inwards to look at the book or screen. Here the eye muscles must work together effortlessly and efficiently.
2. Focusing - The eyes must focus to see the print or screen clearly. Much like a camera changes focus from close to distant objects.
3. Reading Fluency - The eyes must move easily across the page and then jump to the next line. Reading Fluency requires quick eye movements across the line to maintain a high reading speed.
Having even slight eye muscle weakness means your eyes requires extra effort to work together, stay focused and read fluently. This extra effort may fatigue your visual system, causing headaches, a pulling sensation in the eyes, blurred vision, a loss of concentration – or other symptoms requiring vision therapy.
With more severe weak eye muscles, you may be unable to keep your eyes constantly aligned. One eye might drift outwards - known as Lazy Eye. Sometimes the brain turns off the information from the drifting eye which can then develop into a severe Lazy Eye.
Can Glasses fix weak eye muscles?
Glasses can help if the focusing eye muscles are weak (see above) but might not fully help if the convergence or reading fluency is affected -- so often glasses alone might not solve the problem.
Vision therapy can be provided with the FUN computerized HTS Home Vision Therapy Program.
Upon successful completion of therapy, the eyes function comfortably and efficiently as a team. The symptoms will be eliminated or significantly reduced. Near vision tasks will become more enjoyable and rewarding.
