UV sunglasses are eyewear protection that allows only 15% visible light to pass through and block up 99% solar radiation like UVA and UVB from entering your eyes. Many studies indicate that they can cause short-term damage and long-lasting effects to your skin, especially to your delicate eyes.
Exposure under the sun without wearing sunglasses can cause sunburn on your cornea, eyelids and skin around your eyes. The good news is that your body can heal the sunburn in a couple of days without medication. The bad news is that skin damage can be cumulative through years of your life. If your daily activities are usually exposed to UV rays, you may be at risk of developing certain types of diseases like macular degeneration and cataracts sooner or later.
When it comes to fashion, UV sunglasses can elevate your look and pair with other clothes to create stylish outfits. They are a fashion accessory for you to express your personality.
