Glass, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person’s eyes, typically using a bridge over the nose and arms which rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. But Sunglasses are for the safeguard of our eyes from extreme rays and extra disturbing lights. Sunglasses can improve visual comfort and visual clarity by protecting the eye from glare.
Sunglasses offer protection against excessive exposure to light, including its visible and invisible components. The most widespread protection is against ultraviolet radiation, which can cause short-term and long-term ocular problems such as photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer. Medical experts advise the public on the importance of wearing sunglasses to protect the eyes from UV.
