High-index Lenses If you hate thick prescription eyeglasses, try lenses in a high-index material. They offer superior optics in a thinner, lighter lens. Aspheric Lenses 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. Multifocal Lenses 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 and more, but without the lines. You should consider them if you have focusing problems at near. Lens Coatings UV coating and scratch-resistant coating are options that make lenses more attractive and longer-lasting. We can explain how they work and why you should consider them the next time you purchase eyeglasses. Anti-reflective coating Anti- reflective coating allows more light to pass through the lens and enter the eye increasing visual sharpness, rather than be reflected off the lens surface The lens below on the left has anti-reflective coating. See the glare spots on the right lens? Polarized Lenses Polarized lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. This type of lens works great for fishing, boating, driving or any other glare intensive activity. Polarized lenses are the best way to eliminate both glare and UV light. Many polarized lenses feature Anti-Reflective coating on the back of the lens for even better clarity and reduced back glare. Photochromics Photochromic lenses (also called variable-tint lenses or transition lenses) that darken in the sun are convenient for people who spend a lot of time outdoors. Polycarbonate Polycarbonate lenses are very impact-resistant, and thinner than regular plastic lenses. They're great for active people — especially kids. |
