What causes bad eye sight?

A doctor has provided 1 answer

Asymmetrical eyeball: To see well, in the absence of disease or abnormality of the eye and its components, your eyeball needs to be round and your cornea needs to be smooth. If your eyeball is taller or shorter than it is long or if your cornea is not smooth, your vision will be affected and you will need corrective lenses.
