Single Vision is a lens that provides vision correction for one viewable area. The visually corrected area can either be for distances far away or distances close up.
Multifocals are necessary when correction is needed at distance and close up. Multifocals are available in bifocal, trifocal and no-line progressive.
Bifocals have a visible line that provides a area for distance vision and and area for near vision.
Trifocals have two visible lines that provides three viewing areas. One for distance vision, one for near vision and an area for intermediate vision.
No-Line Progressives are the newest design for multifocals. They provide continuous viewing areas and have the added benefit of cosmetically not having any lines. These also tend to be easier to get used to for first time multifocal wearers.
Lenses for Work and Play
Sports Lenses are available and increase the safety and add to the enjoyment of your new glasses. They are available in many different tints, impact resistance, polarized if desired and generally are light weight.
Computer Lenses are very common now with patients desiring a lens custom designed to give the best vision while at their computer. Combining different features along with anti-reflective coatings may reduce eye fatigue.
Glass offers the most scratch resistant material available but must be treated for impact resistance. The downside to glass is that it is very heavy and cannot be used in certain frames. It is seldom used anymore.
Plastic is lighter weight than glass but must be treated with scratch resistant coatings.
Polycarbonate is a high impact resistant lens. We recommend these due to their comfort because they are light weight and due to their high impact resistance, they are safer. This type of material is recommended for children, teens or anyone wanting great protection.
Trivex is a high index lens making it the lightest of any lens material available today. Trivex is gaining popularity do to its impact resistance and great optical clarity.
Transition is a lens that when hit by Ultra Violet rays darkens into a sunglass. It is available in brown or gray. When removed from the UV rays it will lighten up again. This lens will also protect your eyes from UV Rays. Click here for a demonstration of Transition Lenses.
Anti-reflective coating is a coating that is applied to the front and back surface of a lens. The benefit to this is that it reduces irritating reflections allowing for more light to be transmitted through the lens. This allows for better optical clairity, less glare at night with lights & reduced eye fatigue. Anti-reflective coatings applied to computer glasses aid in reducing eye fatigue during computer usage. This coating comes with scratch protection on it.
Ultra Violet Protection can assist with shielding your eyes from UV rays which are harmful.
Scratch Resistant Coating can be applied to plastic lenses to protect lenses from scratching. They may still get scratched but not as quickly as they would without the coating. For prescriptions filled in our office setting, we will warranty most new prescriptions with the scratch coating, against scratching, and will replace a set of lenses once during the first year if it is not due to misuse.
