The first consideration for choosing sunglasses should be the level of UV protection they offer. This can generally be found right on the lenses. Next on the list is the style of the sunglasses. Sunlight can enter the eyes both straight on and from the sides. For serious UV protection look for wrap-around styles. Finally, take a look at the material of the lens. Glass offers a minimal of UV blockage but can be treated to increase protection. Polycarbonate, on the other hand, is an ideal lens material because it blocks most ultraviolet light but UV coating can be placed on any type of sunglasses.
