Heard that glass lenses for eyeglasses are somehow superior to plastic or composite lenses. Any truth to this?
I wear eye glasses. I feel that plastic glasses are a little blurry as compared to glass. Is it so?

Also the eyelashes do flick moisture onto the lenses altering clarity. You should make sure lenses fit. ...Read more
