what is the importance of wearing sunglasses all year long
The importance of wearing sunglasses all year long is to protect your eyes from harmful ultraviolet (UV) radiation. UV radiation is present even on cloudy or overcast days and can cause damage to your eyes. Wearing sunglasses provides the following benefits:
1. UV Protection: Sunglasses with proper UV filters can block 100% of both UVA and UVB rays. Prolonged exposure to UV radiation can contribute to eye conditions such as cataracts, macular degeneration, and eyelid cancers.
2. Glare Reduction: Sunglasses help to reduce glare caused by sunlight reflecting off surfaces like water, sand, snow, or roads. This can enhance visual comfort and make it easier to see objects in bright conditions.
3. Eye Comfort: Wearing sunglasses can prevent eye strain and fatigue by reducing the amount of bright light entering your eyes. They can also minimize squinting, which can lead to headaches and wrinkles around the eyes.
To ensure proper UV protection, look for sunglasses labeled as "UV 400" or stating that they offer 100% UV protection. Additionally, opt for sunglasses that block both UVA and UVB rays. It is recommended to wear sunglasses anytime you are outside, including during the winter or on cloudy days when UV rays can still penetrate through the clouds.
