Summer is almost here!

With the sun now rising and setting a little earlier each day in Edmonton, our thoughts have once again gone back to the topic of sun protection. Sunglasses provide 2 key benefits to patients: reduced exposure to harmful ultra-violet rays and improved visual comfort in bright sunlight. So what is the best option?

Basic Sunglasses

Basic sunglasses simply decrease the intensity of the light around us equally. They help to protect the eyes from the suns harmful ultra-violet rays, and are really one of the best choices for athletes looking for consistent vision during dynamic sporting activities.  Basic sunglasses will typically cost less then polarized lenses and can be found the seasons trendiest new frame styles.

Polarized Sunglasses

Polarized sunglasses decrease the intensity of the light around us, and they reduce or eliminate the reflections or glare that come off flat surfaces like snow, water and roads. By eliminating glare, polarized sunglasses improve visual contrast and help to reduce fatigue and eye strain.  Polarized lenses are best suited for less dynamic activities or flat surfaces like in driving, fishing, boating, etc.

What lens colour is the best?

Lens colour seems to come down to personal choice and fashion for a lot of people. It is a myth however, that darker sunglasses provide more ultra-violet light protection then lighter tints. Darker tints help to reduce more of the suns overall intensity, but quality sunglasses regardless of tint should all block at least 99% of UV-A and UV-B rays. Your eye doctor may recommend darker tints like grey and black during the summer months when the suns rays are far more intense. But during the winter months they may recommend brown tints, as they can add a sense of brightness to a dull flat light day. Light and dark tints are available in polarized and non-polarized sunglass styles, as well as in prescription and non-prescription style sunglasses.
