How could someone with 20/20 sight still require glasses?

For some individuals, they can attain 20/20 sight acuity, but it takes their visual system A LOT of effort to maintain that clarity. For some, that will mean eyestrain or headaches, but for some, they will not experience major discomfort that they are aware of.

Let 's look at a soccer example. You can play soccer with regular running shoes, but you often can perform better if you wear cleats. Why? With the cleats you get a better push off and better traction... less EFFORT to perform the task of running and turning.

In many instances, wearing appropriately prescribed glasses for nearwork can reduce the EFFORT and visual TENSION created by such near tasks. This can help increase ENDURANCE and improve performance.

The 20/20 Myth

Many have been led to believe that 20/20 sight means that one's vision is excellent. Unfortunately, all 20/20 tells you is that you can read a certain sized letter at a certain distance. 20/20 does NOT tell you things such as:

An individual can have 20/20 sight and still have a visual perceptual problem or a learning difficulty that has a major visual roadblock contributing (if not creating) the problem.

An individual can have 20/20 sight and have poor eye hand coordination. They even can have achieved moderate to high levels of success in their athletic endeavors but still have visual difficulties which are hindering them from achieving their potential.

An individual can have 20/20 sight and see words move on the page when reading... or have troubles learning to read... or continue reversing letters/numbers... or have troubles with attention (sometimes labelled ADD/ADHD).
