There are various types of glasses, including prescription glasses, reading glasses, and sunglasses, each serving distinct purposes. Prescription glasses correct refractive errors such as nearsightedness, farsightedness, astigmatism, and presbyopia.
Modern advancements have introduced additional features like blue light blocking lenses, which reduce eye strain from digital screens, and photochromic lenses, which darken in response to sunlight. Frames for glasses are made from materials like metal, plastic, and acetate, offering a range of styles to match personal preferences and face shapes.
Glasses are optical devices worn on the face to correct vision or protect the eyes. They consist of lenses mounted in a frame that holds them in front of the eyes.
