These glasses are designed to remove all the problems associated with visual dyslexia. This size frame fits the adult visual dyslexic. The high quality metal frame is in gold tone with spring hinges and adjustable nose pieces. Lenses are made from special optical quality rare earth metal glass, ground and polished to optical standards to assure distortion free nonprescription vision and then tempered to meet and exceed safety standards for personal use eyewear. This also yields a very hard and scratch resistant surface.
Because the frames are designed for personal wear they do not have the impact resistance required for sport or safety use and should not be used in that manner.
