Glasses as visual aids can compensate for impairments in vision such as myopia or farsightedness. Due to the special shape of the glasses, which is individually adjusted, the incident light is refracted and the focus is shifted to restore visual acuity. Depending on the extent of the ametropia, the thickness of the lenses has to be adjusted accordingly. In addition to prescription glasses, sunglasses are particularly widespread, but glasses with window glass as a purely fashionable accessory are also becoming increasingly popular these days - not least because glasses wearers are perceived as particularly intelligent by most people. In addition, glasses to protect the eyes from injuries (safety glasses) are often used, for example, in the craft and manufacturing industries. (fp)
