One type of specialty eyeglasses that you can buy are called transitions. Transitions are lenses that, when exposed to UV light, turn into sunglasses. This is ideal for people with sensitive eyes, and also for people who are constantly switching from clear eyeglasses to prescription sunglasses. Transitions are usually sold with a few different color options, black and brown being the most popular.
The best part about transition lenses is that the color darkens depending on how much UV light the lenses are exposed to. In other words, if it is very sunny outside, the transition lenses will change to maximum darkness. However, if it is kind of cloudy outside, they will only darken a little bit. Transition lenses are made this way so that you will not have to take them off for being too dark or light. They will change color appropriately to keep your eyes comfortable with the brightness at the time.
Another thing you may want to look at before you order glasses online is polarized lenses. Polarized lenses are tinted lenses (usually black, brown or blue) that are built to give you extremely sharp image. They can sometimes be a little bit pricey, but many consumers say that they are well worth it. If you were to look at a puddle of water or a light through a pair of polarized lenses, you would not see any glare. They are available in both prescription and non-prescription sunglasses.
Polarized lenses are the type of lenses you want if you are a person who spends a lot of time outdoors. They eliminate all glare and rainbow images, while providing the sharpest image you will find with any eyeglasses or sunglasses.
If you are going to order glasses online but want to make them just a little bit better without spending a ton of money, then you might be interested in anti-reflective coating. Anti-reflective coating (or AR coating) is yet another way you can reduce glare and rainbow images, but without entering a different price range.
AR coating is a clear coating that lens manufacturers put on the front and back of the lenses. It is invisible, however, when in the presence of lights the lenses will have a different color glare than that of the lights. It is usually a green or purple glare, and it is very slight. This glare is not seen by the person wearing the glasses, but only by someone looking at the glasses from the front. The glare is the lenses way of deflecting the light away instead of being seen by the person who is wearing the eyeglasses. AR coating has become a very popular customization for eyeglasses and specialty eyeglasses, and many people find it useful.
