The pair of eyeglasses is normal in most aspects except for the fact that it has a pair of lens that are pivotally attached to the framework of the eyeglasses. Each lens of the pair of lens can individually be raised, if access to an eye is needed while the eyeglasses are on. The lens can then be lowered again to allow the individual to use the eyeglasses to see properly.
