How Sunglasses Protect Your Eyes
Sunglasses are more than just a fashion accessory, they are essential for maintaining good eye health.
Ultraviolet (UV) radiation is harmful to both the skin and eyes. UVA and UVB are both dangerous types of UV rays that cause sunburns and skin cancers. The main source of UV radiation comes from the sun, but artificial sources such as welding machines and tanning beds can also be dangerous.
Why It’s Important to Protect Your Eyes
Too much exposure to UV radiation can lead to various eye conditions and vision problems. Photokeratitis is the most common eye condition caused by excessive exposure in a short period of time without eye protection. It is referred to as “sunburn of the eye” since it includes red eyes, sensitivity, and pain but is typically only temporary. However, permanent damage is a possibility. According to the American Optometric Association (AOA), the longer the eyes are exposed to solar radiation, the greater the risk of developing cataracts or macular degeneration later in life.
Benefits of Sunglasses
- UV protection: The UV coating is the most important feature for sunglasses. They block the harmful rays to protect your eyes from the harsh sunlight.
- Clearer vision: Polarized sunglasses block reflected light from surfaces such as water, snow, and metals to increase clarity and reduce squinting.
- All-around protection: Not only do sunglasses protect the eyes, they also shield the skin around the eyes which can help prevent sunburns and wrinkles.
Sunglass lens technology has greatly advanced over the years, but it is still important to know how often to replace your sunglasses. Coatings on lenses break down over time and will absorb less UV rays. Stay protected with all the latest styles.
