Purchasing The Right Sunglasses
By By Tim Gorman 

Sunglasses come in many different styles shapes, colors and even Designer Brands. They can be purchased for as low as $5.00 and go as high as the upper hundreds. But it is not all about personal preference and making a fashion statement. The true function of sunglasses is protection from Ultra Violet Rays.

There are different lenses to choose from when out on the hunt for sunglasses.

* Blue blockers are usually found in amber colors. They are popular with skiers, boaters and especially pilots due to the fact that they block out that blinding blue light.

* Photo chromic lenses are the lenses that adjust the levels of darkness according to the level of Ultra Violet Rays that are being exposed.

* There are also Mirror coated Lenses; they are the best for limiting the amount of light in.

Gradient Lenses are another type of lens that you find on sunglasses. They are darkest on the top and gradually get lighter as the tint reaches the bottom of the lens. They are extremely helpful to people who drive for a living. The other Gradient lens is called double gradient. These lenses are darkest on top and bottom with lighter tint in the center of the lens. They are also not recommended for driving.

The next dilemma in choosing a pair of sunglasses is choosing the color of the lens. They have green shades, blues, reds, browns, greens and even clear. Despite what people might think about the darker colors being more protective against Ultra Violet Rays, as long as they indicate that they are UV protective, you're safe.

Children should also be protected from Ultra Violet Rays. They are out in the sunlight more than adults seem to be, their eyes are more sensitive than and adults and most important, UV damage accumulates over time, so we need to start protecting out eyes as early in life as possible.
