Children's Eye Disease

Children's vision and their vision development

The newborn vision is not as clear as in adult. The development of vision will become gradually clearer by the age of 4 to 5 years. The visual behaviors of children of each age range can be described as follows.

Newborn – 3 months
Children have blurred vision during this age range. They are unable to look directly or trace objects with their eyes and also turn their head away from bright light. Sometimes, it seems that they have strabismus (cross-eye / lazy-eye), but it will disappear when they grow up.
3 months or more
Children begin to look at objects in close proximity especially on the face of their parents, and their three-dimensional vision is also developed. If the children have strabismus in this age range, the ophthalmologist will be able to make a clear diagnosis.
6 months or more
Children have a stronger vision and can identify objects both near and far distance much better. They are becoming more interested in the environment around them, and can also visualize three-dimensional images like an adult.
4-5 years
Children can read numbers normally as same as an adult.
Eye Care Suggestions for Children
  1. They should read in the place where there is enough light that it should not be too dim or too bright.
  2. Do not lie down while reading (lie on your back or on your side) because the gravity will bring the book closely to the face that the eye muscles must work harder more than usual which could overexert the eyes and lead to pain.
  3. Do not read book or play video games in the car because the eyes must be focused more than usual, and the vibration of the car will cause eye fatigue easily.
  4. Do not play video games, computer, computer games and watch T.V. or video continuously for long time. They should rest the eyes periodically by looking further away.
  5. The light of the screen must not be too bright, and it should be adjusted to provide adequate lighting. Do not rely only on screen light.
  6. The children should be encouraged to play outdoors. Do not allow them to watch T.V. or play computer all day especially during semester break

Lazy Eye

Amblyopia (Lazy eye) is the loss of the ability to see clearly through one eye and can occur of over/under using it. The eyes are like any other organs and will deteriorate due to lack of usage and may eventually lead to blindness.


The cause of Amblyopia (lazy eye) may occur from:
  • Children can have unequal eyesight. For example, they may have normal right eyesight and be short-sighted on the left eye at -5.00, hence they will stress on the right side to see more clearly causing the left side to develop the condition of Amblyopia (lazy eye).
  • Children who have Strabismus (cross eye) have difficulty aligning both eyes to see and will use only one eye at the time. In fact, some of them will only use one eye, for example, the right side and have a straight vision but the left side, however, can develop strabismus (cross eye). Consequentially, if the left eye is continuously underused, this side can then also be likely to develop a form of Amblyopia (lazy eye).
  • Children with eye problems one either side (left or right side), for example, their eyelids fall until eyes are closed or affected with unilateral cataract, children will tend to use the healthy side and develop Amblyopia (lazy eye) on the other side.
The Treatment

Amblyopia (lazy eye) can be treated by encouraging children to use their eye side with affected with those vision problems. The ophthalmologist may place a patch on the good eye and/or use eye drops in order to dim the eyesight, thus enabling the children to use the lazy eye. This will help to increase the recovery and improve the eyesight more effectively. The eye closure should be done at an early age because the treatment will be more complicated, and the results will be seen increasingly slower when they are older. Especially with the children at 9 years of age, results for recovery may not be as positive.
