Testing for More than 20/20

So What is 20/20 Vision Anyways?

20/20 just means that the person can clearly see a certain letter on the standard eye chart (equivalent to what a person with normal vision should be able to see at 20 feet). There's so much more to healthy vision than 20/20!

Our comprehensive vision exam goes beyond 20/20 to evaluate many important visual skills, such as:

  • Visual Acuity at Near: Is vision clear and single at close distances? The clear sight at short distances is critical to reading, writing, close work, computer use, etc.
  • Eye Teaming:  Do the two eyes aim, move, and work as a coordinated team? Weaknesses in binocular (two-eyed) vision and eye teaming skills can cause numerous difficulties, including convergence insufficiency and poor depth perception.
  • Eye Focusing Skills: Do the eyes maintain clear vision at varying distances? Rapid, automatic eye focus adjustment is critical to learning, reading, writing, sports, etc. Deficiencies can cause visual fatigue, reduced reading comprehension, and/or avoidance of close work or other activities.
  • Eye Movement Skills: Do eye movements show adequate muscle control, tracking, fixation, etc.? In the classroom, normal eye movements allow rapid and accurate shifting of the eyes along with a line of print or from book to desk to board, etc.  In sports, efficient eye movements contribute to eye-hand coordination, visual reaction time, and accurate tracking.
  • Reversal Frequency:  Is confusion or reversal of letters or words (b, d; p, q; saw, was; etc.) within the normal ranges for a given age?  Past the age of seven, frequent visual and written reversals might indicate a visual perceptual dysfunction.

Above are just a few of the many visual skills evaluated during our comprehensive vision exam.  In addition, the health of your eyes, inside and out, is carefully evaluated for such problems as cataracts, glaucoma, hypertension, diabetes, etc. Contact us at our Lake Grove and Huntington Station eye care offices to schedule an eye exam!
