PROGRESSIVE (No Line Bifocals): These lenses provide all the benefits of bifocals and trifocals, but add the feature of continuous clear vision at all distances, including mid-range distance (arm's length). Progressives have the cosmetic advantage of having no lines, so they never reveal the user is wearing multifocal lenses. Progressives are available in all lens materials. Because of their many benefits, they are the most convenient for patients and most recommended by doctors. Just like the electronics industry, there have been great leaps forward in progressive lens technology in the past few years, giving us the ability to provide the type of "High Definition" vision to our multifocal patients that they experience with their new televisions at home.

SINGLE VISION LENSES: Single vision lenses function as all purpose glasses for persons who have one prescription to see at all distances. People who normally wear bifocals or trifocals can use single vision for "distance only" or "near vision" (reading only) lenses. These types of lenses can also function as specialized occupational glasses for certain types of work or hobbies. Single vision lenses are available in all lens materials.

FLAT TOP BIFOCALS: This is the "original" bifocal form (invented by Benjamin Franklin over 200 years ago!) and is still available today. The user looks above the visible line for "distance" vision, and below the line to read or do close work. The bifocal portion is available in a variety of widths to help with various close up tasks. Flat top bifocals are made in every type of lens material and, of all bifocals, offer the widest area of optically pure vision.

TRIFOCALS: Trifocals are bifocals with an added section in the middle for intermediate distance, providing clear vision at arms length distance. Bifocal wearers will sometimes move up to a trifocal because they need correciton in this area. The user looks through the middle lines to see at an intermediate distance, above the top line for distance, and below the lower line to read. Trifocals come in a variety of designs and widths. Trifocals are available in all lens materials.

OCCUPATIONAL REQUIREMENTS: Many occupations (or hobbies) impose demanding visual requirements on those who wear bifocals or trifocals. Special occupational designs are available to solve these specific needs. If the visual activities of your job fall into this category, let us know and we’ll explain what will work best for your individual needs.

COMPUTER GLASSES: There are a variety of options for those who use computers, including lined and no-line varieties. These lenses are made for intermediate and near vision are and most often recommended with anti-reflective coatings to reduce glare and fatigue associated with computer use.

SPORTS GLASSES:
All sorts of special lens designs are available for the special needs of sports enthusiasts. Polycarbonate is the material of choice for active sports. Vision Park carries "Libery RecSpecs", which can be ordered in team colors. We also make prescription swim goggles (AquaSpecs). Package pricing is available for sports glasses.

Digital Precision for the Best Vision (Without All the Added Hardware)

As you can see, lenses come in countess varieties and combinations! Our opticians will customize a lens solution to meet your lifestyle and needs, based on an individual consultation and our Doctor's recommendations for your best vision.

NON-GLARE LENSES: Your prescription is individually formulated by your doctor using high tech, professional equipment that features non-glare lenses. This "best vision" can be easily reproduced in your glasses by using non-glare lenses, like Crizal Avance. These types of lenses are readily available in all prescriptions. Anti-reflective lenses are particularly effective for reducing eye fatigue from daily activities and driving at night. And think of all the devices you use on a daily basis--phones, computers, gaming devices, blackberries, whiteboards, fluorescent lightling--the list is endless. All of these things produce glare. Non-glare lenses remove distracting reflections and let you get on with your life. And, of course, they enhance appearance by removing all unsightly reflections from the front and back of the lenses, both in person and in pictures. As an added benefit, our premium non-glare lenses carry a 2-year scratch warranty. These are the very best lenses that we can recommend to all of our patients to give them the clear vision they deserve!

POLARIZED LENSES: Polarized lenses are considered the "gold standard" for quality sunwear. They reduce white glare reflected off of shiny surfaces like cars and water, and offer a true, even, "fade-free" tint and total UV protection. Options available include gray or brown color choice, non-glare, and various mirrored coatings. Premium sunwear such as Oakley, Maui Jim and Costa Del Mar all feature non-glare, polarized lenses.

TINTS: Some lens materials can be tinted tinted in-house. Tints are combined with a UV treatment to block out harmful rays. Many color choices are available, in both sun tints and cosmetic tints. Tints come in solid and "gradient" versions.

MIRRORED COATINGS: Mirrored coated lenses give a shimmery appearance to clear lenses, or a metallic or colored mirror effect on sunlenses. Your eye is not visible to others through a mirrored lens. Lenses with this type of coating may be special ordered through our office.

TDII: TDII is a super-tough coating that can be added to most lenses. It is great for kids' glasses or anyone who is "hard on glasses". It is really great for sunglasses, which tend get treated a lot worse than regular glasses. TDII carries a 2-year scratch warranty.

ALL OF OUR LENS PRICES INCLUDE A SCRATCH PROTECTION COATING. (Excludes value collection)

There are more options than ever available for total sun protection. Protecting your eyes from UV rays should be a daily concern, but most of us are guilty of associating sunglasses with summer, when we are participating in outdoor activities. Eyes need protection from UV light 365 days a year. It is that simple. Melonamas can occur in the eye area, just like the rest of your skin. Cataracts have been linked to UV exposure. Eyes are the only part of your body you cannot apply sunscreen to, so use your sunglasses! In addition to polarized sunglasses and clips, Transitions (photochromic) lenses can be a godsend for the sunsensitive. Transitions offer 100% UV protection, whether they are activated or not. They are perfectly clear indoors, but change to dark lenses when activated by sunlight. Transitions are very popular, and available in combination with virtually every material, and anti-reflective lens style. If you would like more information on Transition lenses, or to see a demonstration, visit our optical department.

POLYCARBONATE and TRIVEX: Polycarbonate and Trivex lenses are the most impact resistant lenses available and are always the lens of choice for those under 18 and other active lifestyle patients. If you are at risk from flying objects or physical impacts , this material is the safest choice for you. Polycarbonate is also the least expensive of the "thinner" style lenses, and includes a scratch coating and UV protections at no additional cost. In addition, the lenses we most often use (Airwear lenses by Essilor) are made using environmentally conscious practices such as 100 percent recycled water and 100 percent recyclable packaging. We stock a wide prescription range of these single vision non-glare polycarbonate lenses (our most popular) in-house, so many of these jobs can be done in about an hour.

PLASTIC/CR-39 (Hard Resin): "Basic" plastic lenses come in every prescription and lens combination, including non-glare. They can be tinted for sun with a UV treatment. Most plastic lenses have a "factory scratch" coating applied. Our office does not recommend plastic lenses without scratch coating. One advantage to plastic lenses are the lower price. The disadvantages include less impact resistance, and looking "thick" in higher prescriptions.

LIGHTER, THINNER LENSES: Modern technology has created "compressed" lenses so that higher prescriptions can have a thinner result than those made with conventional materials. These lenses are called "high index". Stronger prescription lenses made with these types of materials are more attractive because they are thinner, lighter weight, and reduce the appearance of "shrunken" or "magnified" eyes in the higher prescriptions.

GLASS: Glass was the first and only lens material available for many years,and still offers superior optics. Glass is also the most scratch-resistant material. The disadvantages of glass are its weight, (generally twice the weight of plastic), it takes longer to manufacture, and can shatter more easily. You cannot use it in a rimless frame style. Due to the wide use of thinner, lighter modern lenses, glass has fewer lens style choices and is expensive.

PHOTOCHROMIC (Transitions): These are lenses that darken as you go from indoors to outdoors. They are available in almost all lens materials. The lenses darken to a moderate shade of gray or brown and will lighten to perfectly clear again when you return inside or are out of direct sunlight. Ask an optician for a demonstration of photosensitive lenses.

Drivewear LENSES are a relatively new high-performance sun lenses (not clear indoors) made especially for those who are always on the road. They are a hybrid of POLARIZED SUN LENSES and TRANSITIONS. Drivewear varies in darkness and tone according to light conditions. The lenses change from pale yellow to dark amber when exposed to UV or visible light, so they work well behind the wheel of a car, unlike Transitions , which is activated only by UV (sun) light. Drivewear is available in single vision, line bifocal, and progressive lens styles.
