Understanding UV Rays and Their Impact on Eye Health
Ultraviolet (UV) rays are a type of electromagnetic radiation that comes from the sun. These rays are invisible to the naked eye but can have damaging effects on the skin and eyes. UV rays are divided into three types:
UVA: These rays penetrate deep into the eye and skin. Prolonged exposure to UVA rays can lead to long-term damage, such as cataracts and macular degeneration.
UVB: These rays are more intense than UVA rays and can cause immediate harm, such as sunburn. In the eyes, UVB exposure is linked to photokeratitis, also known as “sunburn of the eye.”
UVC: These rays are mostly absorbed by the Earth’s atmosphere and do not pose a significant threat to humans.

What Is UV400 Protection?
UV400 protection means that the lenses block wavelengths up to 400 nanometers, which includes all UVA and UVB rays. Sunglasses labeled with UV400 offer nearly 100% protection from harmful UV radiation.
At YMO Eyewear, our sunglasses are designed with UV400 technology to ensure the highest level of protection for your eyes. Our lenses block all harmful rays, protecting your eyes from damage caused by long-term exposure to UV light.
Why UV400 Sunglasses Are Essential
Here are the top reasons why UV400 sunglasses are crucial for protecting your eyes:
Prevention of Cataracts and Macular Degeneration: Prolonged UV exposure can lead to the development of cataracts and macular degeneration, both of which are major causes of vision impairment in older adults.
Reduced Risk of Photokeratitis: This painful condition, often described as sunburn of the eye, is caused by overexposure to UV rays. UV400 sunglasses help prevent this by shielding your eyes from both UVA and UVB rays.
Protection of the Retina and Cornea: UV rays can penetrate deep into the eyes, damaging delicate tissues like the retina and cornea. UV400 sunglasses provide full-spectrum protection to keep these parts of your eyes healthy.
