No matter what your optical prescription, or how you choose to view the world, there are now prescription lenses that meet your unique lifestyle and vision correction needs. Glasses lenses that change as the light changes, from clear indoors to dark outdoors. Bifocal and multifocal lenses that provide multiple fields of vision. High-index lenses that are thinner and lighter than ever before. And progressive lenses that eliminate the traditional lines of multi-focal lenses. The point is, while glasses lenses are prescribed to correct all kinds of vision problems, prescription lenses have come a long way—offering you the opportunity to truly customise your glasses and make a statement about how you choose to look at the world.
