UNDERSTANDING LENS MATERIAL<br />
AND OPTIONS<br />
Sunglasses selection is not just about style. In<br />
sunny climates such as the Caribbean, proper<br />
sunglasses are essential protection for your eyes<br />
from harmful UV rays, and consider polarization<br />
technology that reduces glare and heightens<br />
contrast in your vision.<br />
UV Protection<br />
Your sunglasses must provide protection from ultraviolet radiation, a <strong>com</strong>ponent of sunlight<br />
that contributes to eye disease. The FDA, the government agency that oversees sunglass<br />
manufacture and sales in the U.S., re<strong>com</strong>mends you look for sunglasses with lenses that<br />
block 99-100% of UVA and UVB radiation. The label should read either UV 400 or 100%<br />
