SIX THINGS TO CONSIDER WHEN BUYING SUNGLASSES

Everyone knows sunglasses make it easier to see on a sunny day and also a great fashion accessory. However, wearing the right sunglasses is also a great defense against ultraviolet (UV) rays that can cause short- and long-term eye damage or discomfort.

These are the most important factors to consider when buying sunglasses.

1. Make it 100 percent.
The most important thing to look for when buying sunglasses to protect your eyes is a sticker or tag indicating that they block 100 percent of UV rays. Most people buying sunglasses do not bother to check whether the lenses protect the eyes from ultraviolet light.
The eyes behind the lenses are fully exposed to UV light from the sun because the pupil becomes wider, therefore allowing more light (including UV rays) get into the eyes which exposes the eyes to conditions like cataracts, pterygium and macular degeneration.

2. Bigger is better.
The more coverage from sunglasses, the less sun damage inflicted on the eyes. Consider buying oversized glasses or wraparound-style glasses, which help cut down on UV entering the eye from the side.

3. Darker lenses don’t protect better.
While very dark lenses may look cool, they do not necessarily block more UV rays. They are only helpful for reducing the intensity of light getting to the eye.

4. Color doesn’t matter.
Some sunglasses come with amber, green or gray lenses. They do not block more sun but can increase contrast, which may be useful for athletes who play sports such as baseball or golf.


5. Polarized lenses cut glare, not UV.

Polarization reduces glare or reflection coming off reflective surfaces like water, road or pavement. This does not offer more protection from the sun, but can make activities like driving or being on the water safer or more enjoyable.

6. Cost shouldn’t be a factor.
Sunglasses don’t have to cost a lot of money to work well. Less expensive options marked as 100 percent UV-blocking can be just as effective as more expensive options.
