From these prescription glasses, are born prescription sunglasses. All a person needs to do is shop for a frame, add a lens to it according to the prescription and then choose the best lens tints and coatings as per his fantasy.
Purpose of Prescription Sunglasses
Prescription sunglasses are a boon for people with defective vision. These glasses do not just protect a person's eyes from harmful ultraviolet rays, glare and other toxic particles in the air but also enable him see to see correctly. The prescription sunglasses can be conveniently worn outdoors. They save people from the trouble of putting sunglass clip-ons or put contact lenses while skiing, on beach and doing other activities.
How are Prescription Sunglasses made?
Basically, the prescription sunshades differ from the non-prescriptive ones in case of lens. The prescription sunglasses are available with prescription lenses that are produced and manufactured in a way to include all the customary characteristics of a prescription lens. Prescription sunglasses can be made with single vision, bifocal or progressive lenses (also known as tri-focal lenses with no visible lines). In this the lens material as well as the color can vary from person to person. Similarly the type of lens is also at the discretion of the person. For instance an individual might prefer a high resin and high index lens that can be easily tinted to any color and tint density while other may go with a polycarbonate lens that cannot be easily tinted.
Whereas the frames are concerned, all the designer and celebrity options are open for the prescription glasses. The prescription lenses can be fitted in any trendy frame to complement your attire and over all personality. For instance Penny and Oakley frames accept prescription lenses very well. In order for a frame to accept prescription lens, it should be RXable. Usually the lower quality sunglass frames are non-RXable i.e. they are not designed to hold a prescription lens.
