Protecting Eyes: UV Exposure Risks and Safeguards
Your eyes need protection from the sun just like your skin.
UV rays can harm your eyes, causing problems like cataracts and macular degeneration.
The damage isn't always obvious at first, but it can lead to vision loss.
Sunglasses that block UV rays are super important, even on cloudy days.
Kids and older people's eyes are more sensitive.
Make wearing sunglasses a daily habit to keep your eyes healthy and seeing well.
Eyes lack natural defenses against UV rays, and damage is often unnoticeable until vision loss occurs.
UV-B rays damage the cornea and lens, while UV-A rays affect the retina and can lead to macular degeneration.
Sunglasses should be chosen based on their UV filtration capabilities rather than lens darkness.
Children and older adults are at higher risk from UV exposure due to clearer lenses and cumulative damage, respectively.
Wearing sunglasses daily, just like sunscreen, is recommended to protect against UV radiation.
