All about Eyeglasses
Eyeglasses were invented in Italy around the 1280s to help people see clearly, especially those who had trouble reading. Early glasses were held in front of the eyes or set in frames, and they used simple convex lenses.
Lenses bend light so that it focuses on the back of the eye, the retina. Concave lenses help people who are short-sighted, and convex lenses help people who are long-sighted. Glasses have improved greatly over time and are now light, comfortable and stylish.
