Why do People Wear SPECS ? Why does image get blurred when people don't wear specs ???

Asked by Jaysankar Jayasoman Nair 25th December 2011, 12:00 AM

Image gets blurred when people having eye defects are not wearing specs because
without their specs, the eye can not focus the light rays on the retina. Due to this
defect in their eye, they can not see normally. When they wear specs, then the
lens focuses the incoming light rays on to their retina.
