How Sunglasses Work

Are ten-dollar sunglasses as affective as hundred-dollar
sunglasses? Does price constitute effectiveness? If it is
bright and sunny outside, you may reach for your sunglasses
without even giving it a second thought.

But there are a few key things to think about when buying
those sunglasses, because they do more than just shade your
eyes from the sun.

The right sunglasses could protect your eyes for years to
come from harmful UV rays that could potentially cause
macular degeneration and blindness.

There are four things good sunglasses should do. Sunglasses
should provide protection from the harmful UV rays in
sunlight, provide protection from intense light, provide
glare protection and eliminate specific frequencies of
light.

The right sunglasses made with lenses with polarization,
photo-chromatic lenses or anti-reflective coatings are a
great place to start in protecting your eyes.

You want to select a pair of sunglasses that have a 99% or
100% UV protection. The UV protection is what keeps the
harmful UV rays out and protect you eyes. UV rays can cause
blindness and macular degeneration.

The biggest problem with some cheap sunglasses is the way
the lenses are made. Many are made with ordinary tinted
plastic that does not include the extra coatings and
protections.

If you are an outdoor enthusiast or you spend a lot of time
driving in the daytime, it is important to buy sunglasses
accordingly.

Polarized glasses protect from the glare of water, snow and
asphalt. So you don’t have to spend hundreds of dollars on
the right sunglasses, but make sure you are getting what
your eyes need to keep them safe and healthy.
