Specialty Vision Testing for More than 20/20 Eyesight -

Specialty Vision Examination

Testing for More than 20/20

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? Clear sight at short distances is critical to reading, writing, close work, computer use, etc.

  • Eye Teaming Skills
    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.

  • Visual Perception or Perceptual
    How is the visual information processed by the visual system (eye, brain, and body)? Visual memory, visual spatial awareness, visual closure, figure ground perception, and other vital visual processing areas are tested.
  • 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 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.

  • Visual Motor and Sensory Integration
    How well do the eyes lead the hand and body for both gross and fine motor activities? Balance and coordination in physical activities on the playground or in sports, as well as writing and copying from the board in the classroom can be adversely affected by problems in this area.
  • 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 developmental vision exam.
