It is important to know that a vision screening by a optician / optometrist or Paediatrician is not the same as a comprehensive eye and vision examination by a Paediatric Ophthalmologist. They may not evaluate how well the child can focus his or her eyes or how well the eyes work together. Vision screenings are a limited process and can’t be used to diagnose an eye or vision problem but rather may indicate a potential need for further evaluation. They may miss as many as 60% of children with vision problems. Even if a vision screening does not identify a possible vision problem a child may still have one. Passing a vision screening can give parents a false sense of security. Generally colour vision, which is important to the use of color-coded learning materials, is not tested. Between the ages of 3 and 5 the child should have a thorough, in-person eye examination to make sure his or her vision is developing properly and there is no evidence of eye disease. The advances in diagnostic equipment and tests have ensured that even a pre-school child who does not know the alphabet or how to read, can have his or her eyes examined.
Signs of eye and vision problems
About 10% of pre-schoolers have eye or vision problems. However children this age generally will not voice complaints about their eyes. Parents should watch for signs that may indicate a vision problem, including:
- Sitting close to the TV or holding a book too close.
- Squinting.
- Tilting their head.
- Covering an eye.
- Frequently rubbing their eyes.
- Short attention span for the child’s age.
- Turning of an eye in or out.
- Sensitivity to light.
- Difficulty with eye-hand-body coordination when playing ball or bike riding.
- Avoiding colouring activities, puzzles, and other detailed activities.
If you notice any of these signs in your child visit your Paediatric Ophthalmologist.
