Many of us have gotten with the program and use sunscreens to protect our skin from harmful rays and reduce the risk of skin cancer and aging of the skin. But research is now showing that we need to protect our eyes too. Though sunlight is good for us, stimulating the production of vitamin D–when our eyes are overexposed to sunlight, eye discomfort, blurred vision and even permanent vision loss can result.
The following eye problems are related to this overexposure: sunburn of the front surface of the eye or photokeratitis, cataracts and macular degeneration.
Ultraviolet rays are classified as UVA, UVB and UVC. Only OVA, and UVB reach the earth’s surface. Though UVA are less intense then UVB, they are prevalent and have the power to penetrate deep into the eye. HEV rays (high-energy visible) are also called blue light. These rays also penetrate deep into the eye and may increase macular degeneration.
To protect your eyes and your vision, purchase quality sunglasses that block 100 percent of UVA and UVB rays and filter HEV. An added benefit comes with polarized lenses as they give you extra protection from glare. Children should also wear sunglasses as eye damage accumulates over time. When playing sports, gardening or working outside, glasses provide the additional protection of shielding the eye from flying or protruding objects. Enjoy the sunshine and protect your vision at the same time.
