Spectacle lenses can be made from glass or plastic. Ninety-nine percent of our customers have plastic lenses because they're lighter and safer than glass ones. Plastic lenses come in different densities (called the refractive index) and the higher the refractive index, the thinner the lens is. Thin lenses are lighter and more cosmetically appealing. Westerham Eye Care will advise you on what refractive index will produce the best result for your prescription and chosen frame. We also have lens designs available that give you flatter surfaces and less distortion through the edge of the lens.
