Most avoidable glasses damage happens off your face, not on it. A few storage habits prevent most of it.
The single biggest factor in preventing scratches, bent frames, and lost glasses. A hard case protects against drops and pressure.
If you must set glasses down without a case, place them lens-side up, resting on the temples, never face-down on the lenses.
Never leave glasses on a car dashboard or near direct sunlight -- heat can warp plastic frames and degrade lens coatings.
Taking glasses off with one hand stresses and gradually loosens the hinges asymmetrically over time.
Pushing glasses up onto your head stretches the temples out of shape faster than almost any other habit, and setting them on top of a bag or in a pocket without a case invites both scratches and bent frames from being sat or leaned on.
