ABSTRACT:
An eyeglass system comprising sunglasses or prescription eyeglasses and a detachable ultraviolet, infrared sun shield in one combined unit. The present invention is particularly directed towards a lightweight sun shield system for people who wear prescription eyeglasses. The sun shield component attaches to a slightly modified standard-style eyeglass frame (which thus can be fitted with standard size and shape prescription lenses) and provides further protection against ultraviolet and infrared rays as well as some protection from dust, debris, etc.
