Harmful Effects Of The Sun


There are three types of rays that the sun emits: visible, infrared and ultraviolet (UV). Generally, without added technology, our eyes can see only portions of visible light. But the most dangerous of these rays, that can cause eye damage, are the UV rays. Continuous over-exposure to bright sunlight can damage the eye including the cornea, lens and retina. If the damage to the eye is excessive it can lead to cataracts, or clouding of the lens, or macular degeneration, a breakdown of the macula.

By becoming more educated about the harmful effects of UV rays on the eyes, you will be better able to choose quality sunglasses that are capable of providing lasting protection to you from the irreversible damage to your vision that can result from prolonged exposure to the sun.

Prescription sunglasses are specially designed for people who need vision correction to see clearly while also providing protection from the sun’s rays. Many sunglass companies now make stylist, fashion-conscious sunglasses that also require a prescription.

Prescription sunglasses are designed to protect the user from the harmful ultraviolet rays of the sun. However, polarized lens can provide added protection for the eyes from glare that occurs when light is reflected off flat surfaces such as water or snow. Another great choice is photo-chromatic sunglasses because they have the ability to darken in the sun yet lighten automatically when you go indoors.

Until recently prescription sunglasses were not available in a wrap-around style. The curvature of the lens would cause vision distortion. Now with new technology, prescription sunglasses are available with wrap-around making them very fashionably.

If you require custom-made prescription sunglasses, be aware that they will cost you more and usually no refund is available from the manufacturer. Make sure you work with a reputable company that offers quality prescription sunglasses and first class service.
