UV radiation can be harmful to your eyes year-round, whether it's from outdoor sunlight or indoor sources like welding machines. Protecting your eyes from overexposure to UV rays is essential to prevent long-term damage.
One Day of Exposure Can Cause Damage
Even a single day of intense UV exposure can lead to photokeratitis, often referred to as a "sunburn of the eye." Symptoms include red eyes, a gritty or foreign body sensation, heightened light sensitivity, and excessive tearing. While these symptoms are usually temporary, they can be painful. Fortunately, photokeratitis rarely results in permanent eye damage.
Repeated or prolonged exposure to UV radiation increases the risk of developing serious eye conditions later in life, such as cataracts, macular degeneration, pterygium (also known as surfer’s eye), or even eye cancer. Although it’s difficult to pinpoint how much exposure is harmful, it’s always wise to take precautions when outdoors. A wide-brimmed hat and high-quality sunglasses with UV protection are essential for shielding your eyes from harmful solar radiation.
To ensure your sunglasses offer proper protection, they should meet the following criteria:
Block 99 to 100% of both UVA and UVB rays.
Reduce visible light by 75 to 90%.
Have lenses free from distortion and imperfections, and properly matched in color.
Feature gray lenses for accurate color recognition.
If you engage in outdoor sports or work that could put your eyes at risk of impact, opt for polycarbonate or Trivex® lenses. These materials offer the highest level of impact resistance. For those spending significant time outdoors, wraparound frames can provide extra protection from harmful UV rays.
Children and teenagers often spend more time outdoors than adults, making them more vulnerable to the effects of UV radiation. Protect their eyes with sunglasses designed for UV protection.
UV radiation isn’t limited to the outdoors. Indoor sources like welding machines, tanning beds, and lasers can also pose serious risks to your eyes. During your annual eye exam, discuss any indoor UV exposure with your optometrist so they can assess your needs and prescribe the appropriate protection, including UV-absorbing glasses or contact lenses.
UV protection is vital for maintaining your eye health. Visit your optometrist regularly to ensure that you have the right UV-blocking eyewear for both outdoor and indoor activities. Don’t let harmful rays damage your eyes—take steps to protect them today.
