Lazy eye
When the brain does not properly acknowledge the
information it receives from one of your eyes, this results
in a lazy eye, or "amblyopia." This condition normally
occurs only in children and usually affects just one eye,
which may "wander" around. It can cause serious vision
damage if it goes untreated.
Pterygium
Pterygium is a benign, noncancerous growth that develops
on the mucous membrane on the white part of the eye.
Although they usually don't need treatment, they can be
removed if they cause vision problems.
Diabetic retinopathy
Diabetic retinopathy causes vision problems as a result of
type 1 or 2 diabetes, which can damage the blood vessels
of the eye's retina. It may start as minor visual problems
but it can eventually cause blindness.
