"Glasses, also known as eyeglasses or spectacles, are vision aids, consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person´s eyes, typically utilizing a bridge over the nose and hinged arms (known as temples or temple pieces) which rest over the ears.
Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness.
Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash." - (en.wikipedia.org 02.09.2020)
