The following is a list of some of the more specific enhancements that can be done to your glasses. Some individuals prefer glasses that get darker in the sun, some like a light tint in their glasses all the time. Other folks want glasses to help them see better for fishing. Whatever the task, there are lots of enhancements that can be done to your plain old glasses to maximize your visual performance. Some of these enhancements can be combined and used in your day to day glasses.
Transitions® or photochromic lenses
These lenses darken when they are exposed to outdoor light. Previously they were entirely activated by the non-visible Ultraviolet or UV light. Now the technology has improved to allow a combination of UV and visible light to darken the lens, which produces better results behind the wheel of a car. More recently these lenses can now come in a polarized version, which greatly reduces reflected glare.
Also called “no-Glare lenses”, these lenses dramatically reduce the amount of reflected glare the person sees when looking out of their glasses. They also prevent reflections for those that are looking at the person as well. This is a must for newscasters or anyone working with the public because it removes the reflections you would normally see coming off of that person’s glasses lenses, which tend to be distracting to the viewer. Anti-reflective lenses also help with night time glare while driving, helping to make driving more comfortable.
These lenses are typically used for sunglasses. Polarized lenses work by blocking light that is reflected off of a surface from entering the eye, but they allow some light to pass through. This effectively reduces glare from the dashboard of your car, blinding glare from water or snow on the road, and allows fishermen to see fish below the surface of the water.
Colored or tinted lenses
Did you know that lenses can be made into almost any color? Shooters like to have specific colored lenses for different lighting conditions. This gives them an advantage to see their target by increasing contrast. Some light colored tints can be used for people who are light sensitive especially to indoor fluorescent lighting. There are a variety of tints that can be used in different situations to enhance visual performance for sports or for special jobs.
Digitally made lenses
Digital lenses are those lenses that are made on special equipment that can process digital information. The advantage of digitally surfaced lenses over traditionally made lenses is that the measurements can be more precise to allow your prescription glasses to give you the best possible vision. That means the machine that grinds your lenses will be able to use a combination of front and back surfacing to give you a more precise correction, thinner lenses, and a wider field of clear vision. Digital lenses are especially good for bifocal wearers, those with astigmatism
, or those with higher prescriptions.
