20/20 measures a person’s ability to read a specific sized text at a specific distance, but vision is much more than 20/20.
Someone with 20/20 eyesight can still have an issue with their vision.
Many people believe that 20/20 vision means that vision is excellent. Unfortunately, 20/20 does not tell you the following:
- how long and how comfortably you can read that text
- how your brain interprets that information
- how well you can transfer from working on a near task to a distance task and back
- whether your eyes are tracking efficiently
- if your visual perceptual skills are strong
- that your binocular coordination is efficient
- whether you will be able to perform well in sports
Some people with 20/20 vision may still face fhe following visual issues:
- have a learning difficulty or a visual perceptual problem
- have poor eye hand coordination
- have visual difficulties which are hindering them from achieving their potential in school and sports
- see words swim or move on the page when reading
- have troubles learning to read
- reverse letters and/or numbers
- have troubles with attention
The right vision screening can help.
Dr. Juanita Collier, MS, OD, a Behavioral Optometrist who owns 4D Vision Gym in Cromwell, says children who struggle in school may have a learning difficulty that is due to a vision problem that goes undetected by standard vision tests. A developmental visual issue may be causing them to underperform or work harder with minimal results.
Dr. Collier recommends that school children be given a near-point vision screening, in addition to the standard distance vision screening, in order to reveal any visual issues that may exist. This type of screening is very different from the typical eye chart children are asked to read.
A near-point vision screening tests a child’s ability to:
- see clearly at near;
- point both eyes together on a target at the same place at the same time;
- use both eyes simultaneously; and
- perceive depth.
