Light, in general and, sunlight in particular is comprised of many units called wavelengths. Each wavelength has a different level of energy ranging from low energy at the red end of the spectrum, to high energy at the blue end. The ubiquitous UV light we hear so much about is situated next to the blue light, and has the highest and most dangerous amount of energy. It is this wavelength of light that we are most concerned with in regard to damage to the eyes.

When this high energy light enters the eye, it is absorbed into the ocular tissues. This energy then acts as a catalyst for an increase in tissue metabolism, and that is when the trouble begins. Individuals with a genetic predisposition toward Macular Degeneration can expect a dramatic increase in the severity of the condition, and a substantially earlier onset of the disease. Systemic disorders such as Diabetes will also put an individual at risk for this disorder. The natural lens in the eye is comprised of Alpha proteins; which are clear. When exposed to UV light, they undergo a chemical change that transforms them into Beta proteins which are yellow. This process is called cataractogenesis and results in cataract formation.

Choose the Sunglasses with hight quality and don't think of his price, because damage of eye is not protected will be more costly again.
