Frames with lenses worn over the eyes to help you see clearly, also called spectacles or glasses.
Compound of 'eye' (from Proto-Germanic) and 'glasses' (from 'glass'); the term came into use after eyeglass lenses became common in the 1500s-1600s.
It's funny that we still call them 'glasses' even though modern ones are often made of plastic—the material name stuck around for 500 years even though it changed.
