The ability to block the UV rays has got nothing to do with the shades and darkness of the sunglasses. Preferably a wraparound sunglass with a wide lens and close-fitting frame could prove beneficial as it will protect from every possible angle. There are contact lenses also that offers UV protection but this provides best results only when worn along with sunglasses.
While in the outdoors protection from the scorching UV rays by choosing the right sunglasses is inevitable. Long term UV rays exposure can damage the eye surface and the internal structure. Optometrists and ophthalmologists recommended brimmed hats and sunglasses while venturing out in the sun for a long duration. Moreover, even while trying to get a suntan on the beaches, wearing sunglasses is advised.
Many are of the wrong opinion that sunglasses that are highly priced offer good protection. Some sunglasses from the drugstore also prove to be effective to protect from the harmful rays of the sun. So, expensive glasses always do not guarantee the best protection. Some of the aspects to look out for while choosing a sunglass include:
UV protection label Choosing sunglasses with 99 to 100% UV block is advised. Never be deceived by the color of the lens of the cost. A dark lens does not mean it could absorb UV rays better. Certain chemicals are added to the lens to absorb UV rays. There are certain sunglasses that are labeled 400nm, this means 100% UV protection.
Wraparounds For best protection from sun’s rays, use a wraparound. Sunglasses wrapped around the temples prevent sun’s rays entering from the sides. Studies have revealed that UV rays entering from the sides of the sunglasses can cause harm and reduces the benefits of the glasses even if it is 100% UV protected.
Lens quality Buy uniform tint glasses and check for any imperfections. You can check for this by holding the glass at the arm’s length and look in the straight line. Move the lens slowly across the line, if you find any distortion or curves or unnecessary sways, then the lens is of poor quality.
Value-added features Some lens comes with specialized features for better effects. Polarized lenses can remove the reflected glare. This is helpful while driving or in the snow. Mirror coating uses thin metallic layers to reduce visible light. It can be used in high glare environment. Photochromic lens darkens in bright light and lightens in low light. Gradient lenses are permanently shaded and are designed to cut the glare.
