Does a child wearing minus numbers means the eyes are “weak”?
A. NO. Minus numbers is referred to as ‘myopia’ or short sight. This means that the child can see well for near but has problems seeing for distance. This is because the focusing system of the eye i.e. the cornea and the lens bend the rays of light too much so that they focus in front of the retina. Hence myopia means the eye is too strong or powerful and certainly not weak.
