history: I have an amazing eyesight
knowledge: Visual acuity is dependent on optical and neural factors, i.e., (i) the sharpness of the retinal focus within the eye, (ii) the health and functioning of the retina, and (iii) the sensitivity of the interpretative faculty of the brain.
response: 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
knowledge: Causes of refractive errors include aberrations in the shape of the eyeball, the shape of the cornea, and reduced flexibility of the lens.
response: Splendid.  You may know then that refractive errors include deviations in the normal shape of the eyeball, or the cornea, and also the flexibility of the lens being reduced.

Wow! that is very interesting. Sometimes other factors such as computer use may also affect vision.
knowledge: Another common impairment, amblyopia, is caused by the visual brain not having developed properly in early childhood.
response: Oh yes?  There is a common impairment called amblyopia.  That is caused by improper development of the visual brain in early childhood.

How common is it ?
knowledge: Another common impairment, amblyopia, is caused by the visual brain not having developed properly in early childhood.
response: I'm not exactly sure.  Its cause occurs in early childhood though.

Is there a cure ?
knowledge: After the underlying cause is fixed, vision is not restored right away, as the mechanism also involves the brain.
response: Yes there are some procedures which can fix it which involve dealing with the underlying cause.
