Progressive Multifocal Lenses

If you are over 40 and having difficulty with your vision, chances are you are experiencing presbyopia, the common gradual loss of near vision. But there is good news: you have more choices today than ever before. You don't have to carry a separate pair of glasses for reading or wear lined bifocal lenses like your parents did. Progressive lenses offer a smooth transition from distance vision through intermediate vision to near vision, and they supply all the in-between corrections as well. This means that instead of having just two different viewing zones (near and distant), like with bifocals, progressive lenses have progressive powers of correction (from bottom to top), easing eye strain and providing the most natural vision correction.

Our office has a sixty-day non-adapt warranty on progressive multi-focal lenses. If it is determined that you are unable to adapt to your new multifocal lenses, we will remake your lenses to single vision or a lined bifocal at no additional cost.

Digital High Definition Lenses

Do you have 20/20 vision when you wear your glasses but still feel dissatisfied with how you see? You might benefit from high-definition digital lenses. Sometimes, higher-order aberrations can affect your vision. These aberrations may be due to the optical characteristics of your eyes or can be caused by the optical limitations of conventional eyeglass lenses. Digital lenses are designed to provide sharper vision in all lighting conditions and reduce glare for night time driving and other night vision tasks.

The most popular type of high-definition eyeglass lenses are called free-form lenses. The term "free-form" refers to an advanced manufacturing process that reduces higher-order aberrations such as spherical aberration that occur in eyeglass lenses created with traditional eyeglass lens manufacturing tools and processes. With free-form lenses, the fabrication of the lenses from wearer's eyeglass prescription is optimized with computer-controlled surfacing equipment that is much more precise than conventional tools. In fact, free-form technology can surface lenses in power increments of 0.01 diopter (D), compared with 0.125 to 0.25 D increments of conventional eyeglass lens tooling. Virtually anyone who wears eyeglasses is a good candidate for high-definition eyeglass lenses, but individuals with higher eyeglass prescriptions may notice greater benefits than people with only mild prescriptions. Perhaps one of the best indicators that high-definition eyeglass lenses might be a good choice for you is if you are bothered by glare or your vision seems indistinct.

If you are dissatisfied with the clarity of your eyesight with your current glasses, ask your eye care professional if high-definition eyeglass lenses might provide sharper vision.
 

Computer Lenses

Occupational progressive lens differ from regular multifocal eyeglasses in a number of ways to optimize your eyesight when viewing your computer screen. Computer screens usually are positioned 20 to 26 inches from the user's eyes. This is considered the intermediate zone of vision — closer than driving ("distance") vision, but farther away than reading ("near") vision. The occupational progressive lens is a no-line multifocal that corrects near, intermediate, and, up to a point, distance vision. It has a larger intermediate zone than regular progressive lenses for more comfortable vision at the computer. It does, however, leave less lens area for distance vision. While you can comfortably navigate your office, these lenses are not recommended for driving or other significant distance vision tasks. Multifocal computer eyeglasses put the optimum lens power for viewing your computer screen right where you need it for a clear, wide field of view without the need for excessive focusing effort or unhealthful postures. If you think you might be interested in trying computer lenses, prior to your eye exam, measure how far you like to sit from your computer. Measure from the bridge of your nose to the surface of your computer screen. Bring this measurement with you to your exam so your eye doctor can use it to help determine the optimum lens power for your computer glasses.
