Most groups agree that newborns should be checked for general eye health by a pediatrician or family physician in the hospital nursery. Around the age of 3 1/2, children should be screened for eye health and tested for visual acuity by their doctor.
There are some that suggest that a higher number of dyslexics have required or should have been wearing corrective lenses from a very early age. Thus suggesting that a few of the symptoms of dyslexia might be less for a child that has poor vision if they are wearing corrective lenses as early in their life as possible. (perhaps as early as 1 or 2 years of age)
The logic behind the conjecture is fairly simple and logical. While the child’s brain is developing, learning how to organized and associate images to words & sounds, etc., if the child cannot see the image, how can the brain correctly associate the object to the word? Thus creating part of the ‘cross wiring’ problem that most dyslexics display.
At this time there is not solid proof that having a child’s eyes checked at an early age and wearing corrective lenses, when needed, will stop or even reduce any of the effects of dyslexia. However, I believe having a child’s eyes checked, as early as possible, and on a repeating schedule is something that parents should do (especially parents with a history of dyslexia in their family). For a very young child does not know if they are seeing clearly or not. (If you have seen blurry images all your life it is natural to assume that everything is suppose to look that way).
Even if wearing corrective lenses as soon as needed does not help reduce the symptoms of dyslexia, it is something that is not a waste of time or money. For it will still have other long lasting and ‘visible’ results.
A short list of standard things that might suggest a child should have their eyes checked:
constant eye rubbing
extreme light sensitivity
poor visual tracking (following an object)
abnormal alignment or movement of the eyes (after 6 months of age)
chronic redness of the eyes
chronic tearing of the eyes
a white pupil instead of black
inability to see objects at a distance
does not recognize people or things at a distance
sitting too close to the TV
