An attachment for eyeglass frames which permits the wearer to quickly replace lenses without the use of optical hand tools or equipment, and which does not require the dexterity usually associated in working with miniature optical parts. The invention is permanently affixed to the eyeglasses, eliminating the possibility of loss, damage or disconnection. The invention is designed for use in instances where changing light conditions necessitate the need for tinted or sunglasses but where carrying additional frames is neither practical or desireable.
