Eyeglass Lenses

The most important part of your eyeglasses are the lenses, and not all lenses are equal in quality and design. That is why we feature Hoya lenses, a world leader in lens technology and quality.

Corrective lenses are used to correct refractive errors of the eye and alleviate the effects of conditions such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism and presbyopia - a condition that reduces the ability of the lens in older patients to focus on objects close to the eye.



Types of Corrective Lenses

Single Vision lenses have the same optical correction over the entire surface of the lens. For more information on single vision lenses visit: Hoya Single Vision Lenses

Bifocal lenses use the upper part of the lens for distance vision, while the lower part is used for near vision. Usually, a segment line separates the two.

Trifocal lenses are similar to bifocals, except that the two focal areas are separated by a third middle area used for intermediate vision, roughly at arm's length. This lens type has two segment lines dividing the three different correcting segments.

No-Line Bifocal Lenses or Progressive Addition Lenses (PAL) eliminate the lines in bifocal and trifocal lenses. The progressive lens has a very complex design that provides a smooth transition from distance correction to near correction without disruptions, distortions or lines.

Computer lenses are progressive lenses designed to maximize intermediate range vision and are especially helpful if you spend a lot of time on a computer. The lenses reduce the chin-up posture required with bifocals and conventional progressive lenses. Computer lenses also reduce eyestrain with the use of a much wider intermediate viewing area.

Lens Performance Enhancements

Photochromic lenses change from light to dark and back again depending on exposure to the sun’s ultraviolet (UV) radiation. We feature Transitions® products, a leader in photochromic technology. For more information visit: Transitions

Polarized lenses, most frequently used in sunglasses, reduce glare and haze from highly reflective objects like bodies of water and automobile windows. This lens improves vision clarity and comfort in outdoor environments and driving.

Scratch-Resistant coating is a good investment since plastic lens material is relatively soft and susceptible to scratching during normal use. Many of our lenses come with a scratch-resistant coating. Be sure to ask about our scratch-resistant coating options.

UV Protection is strongly advised since ultraviolet rays from the sun can damage your eyes and have been associated with cataracts and retinal damage. Many of our lenses come with UV protectant and it is recommended for all lenses you wear.

Anti-Reflective (AR) coatings significantly reduce reflections on the front and back of the lens making the eyes more visible. More importantly, AR coatings improve the efficiency of the lens by allowing more light to enter the eye, improving contrast and thereby increasing visual clarity. AR coated lenses also produce less glare that is particularly noticeable when driving at night or working in front of a computer monitor. We recommend Hoya’s EX3 AR coating, a five-layer coating that is more scratch resistant than glass and comes with a two-year warranty and unlimited replacements.
