I have an amazing eyesight
Visual acuity depends on three things, sharpness of the retinal focus, eye health, and sensitivity of the brain.
Yes I know. I've done a lot of research about it in the past
Do you know why people have poor eyesight? Commonly they are refractive errors like the shape of the cornea and reduced lens flexibility.
Wow! that is very interesting. Sometimes other factors such as computer use may also affect vision.
Yes although there is a common impairment which is caused by the visual brain not growing enough in early childhood.
How common is it ?
It is called amblyopia and apparently is it very common and happens in a large number of children.
Is there a cure ?
Yes there are some procedures which can fix it which involve dealing with the underlying cause.
