Even if they are careful, the average wearer of spectacles usually ends up parking their glasses, by accident, face down on some hard surface. The high cost of anti-scratch lens coating (which never really seems very effective) can be avoided entirely by use of today’s invention.
A pair of small, translucent plastic knobs are attached to the front of one’s spectacles, using two small self-adhesive pads. These are positioned at the top outer corners of the lenses, on the opposite side from the legs.
If the specs decide to roll forward onto the lenses, the protruberant knobs make it impossible for a flat surface to come into contact with any part of the optics themselves.
