Sorry I meant to say "middle" layer of eye. (layers are sclera, choroid, retina in back of eye). The likelihood of turning into a malignant tumor depends on size, shape, elevation, coloration, smoothness of borders and whether fluid over it or not. It needs a MD to determine these.

a choroid nevus is a mole in the inner layer of the eye. My suggestion is hold off on the glasses and see a MD eye physician ophthalmologist for a consult on both the mole and the glasses.
Ask your family MD to refer you or go to www.geteyesmart.org and find and Eye MD near you
