Anti-Reflective Coating Normal lenses often create glare, reflections, and “ghost images.” Now that can be eliminated with an anti-reflective coating.
What we see is a result of light being sensed by our eyes. With normal glasses much of the light reflects off the lenses. This produces glare. It also reduces the wearer’s visual acuity. In other words the light reflections are a cosmetic and visual problem. Anti-reflective coatings increase light transmission through the lenses to 100%. It makes it easier to see and easier for others to see you. These coatings are especially useful for those viewing computer screens and driving at night. High-IndexHigh index materials are named because they have a higher index of light refraction. When speaking about high index lenses, you may hear many unfamiliar numbers and terms. Here are a few things to remember. High index lenses, such as 1.6, 1.67, 1.74, 1.8 and 1.9, are much thinner than regular glass or plastic. Talk with one of our Opticians to decide which high index lens is right for you. Progressive LensesProgressives provide a smooth transition from focusing on nearby to focusing on distant objects because they do not have a distinct line which separates the focusing powers. Instead, a gradual change in power allows the wearer to focus on objects at all distances. Distant objects are viewed through the upper portion of the lens while near objects are viewed through the middle or lower portion of the lens. Specialty LensesThere are many lenses available for different tasks and for just about anybody. No matter what your particular need there is a specialty lens designed for you. For example, a specialty lens that is becoming increasingly useful is designed for computer users. Computer lenses have specific areas designed for viewing your computer screen, documents on your desk and anything else within a close range. PhotochromicsIf you’ve ever felt frustrated at needing prescription glasses and prescription sunglasses to accommodate an outdoor lifestyle you should consider photochromic lenses. Photochromic lenses darken when exposed to UV rays. When the wearer goes outside the lenses darken or tint. When the wearer goes back inside the glasses become clear. There are a variety of photochromic options available. Depending on what you choose, you can customize the lenses to your needs. Polarized Lenses Glare from water, wet roads, light reflecting off other vehicles and glare from your own windshield can be annoying and dangerous. To eliminate this glare we offer polarized lenses. Polarized lenses are the most effective way to reduce glare, eye strain and increase visibility.
Polarized lenses can make a world of difference for any outdoor enthusiast. Fisherman and water sport enthusiasts can eliminate the bright reflections from the water and actually see into the water more easily than with any other sunglasses. Golfers can see the green easier and joggers and bikers can enjoy reduced glare from the road. In addition, drivers can enjoy the safety and comfort that polarized lenses provide while driving. Bifocal LensesFor many people different lenses are needed for seeing at different distances. Bifocal lenses allow the wearer to look through two areas of the lens. One area focuses on distant objects. The other is used for reading. Trifocal LensesBifocals allow the wearer to read through one area of the lens and to focus on distant objects through another area of the lens. As the eyes age though a stronger prescription is needed to read. The stronger prescription required for reading makes it difficult to focus on objects at intermediate distances such as grocery items on a shelf or your speedometer. Thus, trifocals are necessary for a third prescription for intermediate focusing. One of the main problems with bifocal and trifocal lenses is the problem of eye fatigue. It is difficult to switch from one focusing power to another. It can make your eyes tired and can lead to a headache, sore neck and sore back. Scratch Resistant CoatingIf you have hard resin lenses you should consider getting a scratch resistant coating. Resins and plastics are more susceptible to scratches than glass. Scratches damage the cosmetic look of the lenses as well as their performance. With a scratch resistant coating, you don’t have to worry so much about minor scratches on your lenses. They are a great investment to prevent minor scratches. However, it is important to remember that scratch resistant does not mean scratch-proof. All lenses are susceptible to scratches.
