In the last few years there has been a sudden increase of new products introduced into the optical industry. All this new technology has enabled us to satisfy various needs that we were unable to satisfy a few years ago. So if you were told that you could not get a progressive lens in the frame you really liked, odds are that now you can. For those who are not too comfortable with lenses, but need some information on eyeglasses, look no further. Many new eyeglass lenses are available today, with their own specialization.
Aspheric is perfect for strong prescriptions because they are flatter and thinner. In addition, they provide better vision than ordinary lenses and look better because they lessen farsighted and nearsighted eye magnification. Bifocals and trifocals come in many configurations, depending on whether you sit at the computer all day, play golf, or work on automobiles. Progressive lenses can do everything a bifocal or trifocal can, but without the lines. Anti-reflective finishes, UV coatings and scratch-resistant finishes are options that make lenses more striking and longer lasting.
Polycarbonate lenses are impact-resistant, and thinner than normal plastic lenses. They’re great for active people — especially children. Industrial and occupational lenses have special occupational designs which allow dispensers to customize lenses for virtually any occupational or safety requirement. Be sure to discuss with your optician the tasks you do at work, and also what you do in your spare time in order for them to judge your requirements correctly.
Computer lenses are required if you are viewing a computer video display terminal for more than two hours a day. These lenses help correct vision for the specified distance from your eye to the computer screen and its immediate surrounding area. A variety of computer-specific lenses include special filters, tints, and anti-reflective properties, which can be added to enhance eyeglass features.
