If you hate thick prescription eyeglasses, try lenses in a high-index material. They offer superior optics in a thinner, lighter lens. Aspherics are ideal for strong prescriptions because they are flatter and thinner. They also provide better vision than ordinary lenses and look better because they lessen farsighted eye magnification and nearsighted eye minification.
Eyeglass Lens Coatings
Anti-reflective coating, scratch resistant coating and UV lens treatments are options that enhance your vision and appearance, increase the durability of your eyeglasses and protect your eyes from the sun's harmful rays.
The lens at left has anti-reflective coating.
Bifocals and trifocals come in many configurations, depending on whether you sit at the computer all day, play golf, work on automobiles, etc.
Progressive Addition Lenses
Progressive lenses can do everything a bifocal or trifocal can do, but without the lines.
Polycarbonate and Trivex Lenses
Polycarbonate lenses are very impact-resistant, and thinner than regular plastic lenses. They're great for active people — especially kids.
