Fashion and Function

With summer just around the corner everyone is out shopping for the newest shades. Though sunglasses are maybe the easiest accessory to wear with your cute summer outfit it’s important to remember that, like glasses and contacts, they are still medical devices. The intended purpose of sunglasses is to protect your eyes from the harmful UV rays.

UV Rays and Your Eyes

After UV rays have entered the atmosphere they enter the eye through the cornea. The light then passes through the cornea to the pupil and moves to the iris where light intensity is controlled. Unfiltered UV light causes damage to the eyes. UV damage is cumulative and you will be able to see and feel the UV effects over time.

Children are even more susceptible to UV damage since the lenses of their eyes are still forming.

The History

The first pair of sunglasses was sold in 1929, and the first pair of polarized sunglasses were purchased shortly after in 1936. Today they are available widely from fashion shops, to optical stores and optometrists clinics. Though we all choose our sunglasses based on how they look on us, few of us remember to look for the health and safety information when choosing this accessory. It’s important for the health of your eyes and the surrounding skin that you choose sunglasses with 100% UV protection.

Once you’ve confirmed the sunglasses will protect you from harmful light you can begin looking at the style of the frames and the type of lenses.

Polarized Lenses are one of the best options to reduce glare while increasing visual performance while wearing tinted lenses. They contain vertical polarized filters that counter reflected sunlight from surfaces such as water or car windows. Preferred by athletes who require clear vision to perform.

Mirrored Lenses are lenses with a reflective coating on the outside of the lens to make them appear like small mirrors. Essentially one way mirrors, they are available in a variety of colours.
