Spectacles, also known as eyeglasses, are worn to correct vision problems such as nearsightedness, farsightedness, or astigmatism. They work by bending light rays that enter the eye in a way that helps the eyes to focus properly on objects. Spectacles can also protect the eyes from harmful UV rays, dust, and other environmental particles.
