Shopping for Sunglasses

When shopping for sunglasses look for a label that specifically promises 99% to 100% UV protection.  it is especially important to wear sunglasses at midday and at any higher altitude where the UV light is more intense. UV rays have to pass through haze and thin clouds. Sunglasses should  be able to block both UVA and UVB radiation. A label that reads "UV protection up to 400nm" usually means 100% UV protection.

Choose polarized lenses that eliminate any reflected glare -- sunlight that bounces off smooth surfaces like pavement or water. You can buy a good quality pair of sunglasses with UV and glare protection for  from $35 to $50. A higher price doesn't always mean the sunglasses are better quality.

A medium-tinted lens is good for usual day-to-day wear, but if you use the sunglasses for very bright conditions, select a dark tint. Gray and green-gray are popular general-purpose tints that reduce glare while still maintaining natural colors.

Choose large-framed, close-fitting, wraparound glasses that are comfortable.  Make you feel that they look good on you. Wraparound sunglasses are shaped to keep light from shining around the frames and into your eyes. 

Plastic lenses are less likely to shatter than glass lenses. Some sunglasses use polycarbonate plastic, which is a special material that is strong but they can be easily scratched. So look for polycarbonate lenses with scratch-resistant coatings. All sunglasses must meet impact standards set by the FDA for safety, but absolutely no lens is truly unbreakable.

Shopping for sunglasses shouldn't be difficult when you know what to look for.
