Here is a sunglass that you can wear at anytime when outdoors. No longer do
you need to have a clip on for your regular glasses. If your in a windy, dusty
or beach environment you need not worry about having
contacts in your eyes. Just
put on your prescription sunglasses and your ready to go.
If your concerned about style you will be happy to see that the styling of
sunglasses are the same as all glasses and
frames. You have the option of
designer, celebrity and fashion glasses and
frames to choose from.
As for the lenses used in sunglasses you will find that there choices from
the basic lens to high prescriptions as well as bifocal and progressive lens
You can choose a lens that darkens when you go from a room environment to a
sunlight environment. This is known as a photo chromic lens. Be aware though,
these type of lenses do not normally have UV protection built in. To have the UV
protection you will have to ask to have a UV coating applied to the lens.
There are many materials your prescription sunglass lenses can be made from.
These include glass, regular plastic, high-index and polycarbonate. The
high-index and polycarbonate materials are ones you should look for in the
sunglasses. They are a much more lighter and stronger lens.
