Sunglasses – Strength and Protection

At this time of year we spend more time outdoors and for that reason it is important to protect our eyes from the potentially harmful rays of the sun. One of the ways we can do this is by wearing the right sunglasses.

Don’t be fooled by the price tag when purchasing sunglasses. Just because sunglasses are expensive doesn’t always mean that they are the best at blocking the UV rays. Always check the label first.

For sunglasses to be completely effective they should:

  • Block out as close to 100% of the UVA and UVB  rays as possible
  • Block out 75 to 90 percent of the visible light
  • Have gray lenses for proper color recognition

If we are exposed to too much UV rays, over time, it can cause cataracts and can also harm the cornea and the retina. Short term exposure to UV radiation can cause photokeratitis, an inflammation of the cornea. It is temporary in the short term but can have serious consequences long term.

It is also important that sunglasses fit properly. They shouldn’t be worn so close that they touch the eyelids yet not too far off that they let sun get in around them.

A good rule to follow is if you are wearing sunscreen you should also be wearing sunglasses.
