Your sunglasses should protect 100% of UV rays and also filter out UVA, UVB and UVC. should also remember that despite the colour or darkness of the lens, it is the cr outer coating that filters the rays and not the colour.

However, the colour of the lens and the construction of the glasses can affect your vision in different ways. range of for which people require their sunglasses is probably some with interchangeable lenses such as the Birdz Hawk sunglasses kits.

For example, some tints can elicit colour distortion that can affect driving performance. Driving glasses need to kp you alert and kp your eyes comfortable causing headaches. Look for polarised lenses for driving, preferably with a grey tint as this is neutral and would not affect contrast or distort colour.

If you are a golfer, yellow is the colour of choice as it enhances contrast and depth perception. cycling, you really need a tougher lens as you should consider the increased airflow to the face, you will also need to protect the peripheral vision and consider the fit of the cycling helmet with the glasses.

There are a few sports that demand particular safeguards for sunglasses. example, for mountaineering and other hh altitude sports, you should consider the possibility of extremely bright conditions as well as the altitudes. Altitude sports gy require a category 4 lens that take these conditions into account. Glasses or goggles required for water sports such a surfing or kayaking etc., should be shatter-proof, should not mist up, have a nose cushion, be buoyant and have a means of fixing such as a strap. example, Electric and Oakley have a reasonable range of quality sunglasses and goggles.
