Sun Protection For Your Eyes

This image is no longer available


It is well known that exposure to the sun can be very harmful to our bodies and causes irreversible damage if proper care is not taken. While many people understand the need to protect their skin from the sun, the eyes are often neglected.

Among many factors that contribute to the formation of eye diseases, prolonged sun exposure is proven to speed up the progression of cataracts and age related macular degeneration.

One of the best ways to protect your eyes is by wearing sunglasses. They act like sunscreen for the eyes. Unfortunately, not all sunglasses are created equal. It can be hard to know what to look for when trying to pick the right pair.

7 Features Of A Good Sunglass:

  1. 100% UVA/UVB protection
    • Check packaging to confirm quality 100% UVA/UVB protection.
  2. Blue and Violet Light Blocking Filter
    • Blue light may not be as harmful as UV rays but shows increasing evidence of damage to the eye.
  3. Polarization
    • Is one of the best options to reduce glare while increasing visual performance & preserving eye health.
  4. Back Surface AR Coating
    • By adding Back Surface AR to the inside of your shades; you can minimize glare and prevent reflection back into the eye.
  5. Selective Color Filtering
    • Selectively blocks some wavelengths of light while allowing others through. This is useful if you suffer from light sensitivity.
  6. Full Physical Wrap
    • Decrease the amount of “light leakage” caused by light entering from the top or sides of your sunglasses.
  7. Distortion Free Optics
    • High quality materials and high-level lens technology will minimize the amount of distortion a lens can have when trying to fit a specific sunglass frame.

Quick Fact:

A poor pair of sunglasses may actually increase the risk of eye damage. Sunglasses by their nature dim the light reaching the eye, causing the pupil to open. If the sunglasses being worn fail to block the proper light rays, there is a larger opening for light to travel through and an increased opportunity for tissue damage.
