The Connection between Ultraviolet (UV) Radiation and Eye Health

Connection Ultraviolet

and Health

The sun is an important source of Vitamin D, but it also contains ultraviolet (UV) radiation that can damage the eyes and the skin. UV radiation is divided into UVA, UVB, and UVC. UVC radiation is typically blocked by the atmosphere, while UVB radiation is partially filtered out. UVA radiation has the capacity to penetrate the atmosphere and get deeper into the layers of the skin and eyes.

The Effects of Ultraviolet (UV) Radiation on Eye Health

The ultraviolet rays of the sun’s radiation can damage the eyes in several ways. These include:

  • Cataracts: The long-term exposure to UV radiation over a period of time may increase the risk of developing cataracts. Cataracts are a clouding of the eye’s lens which can lead to vision loss.
  • Macular Degeneration: UV radiation can also increase the risk of developing age-related macular degeneration, a condition in which the vision in the center of the eye deteriorates.
  • Pterygium: UV radiation can lead to an abnormal growth of the conjunctiva, the white part of the eye. This is called pterygium, and can cause redness, irritation, and blurry vision.

Preventing Damage from Ultraviolet (UV) Radiation

The most common ways to protect oneself from UV radiation are to wear sunglasses, wide-brimmed hats, and to stay out of the sun during its peak hours. It’s recommended that individuals use sunglasses with UVA and UVB protection and a higher transmission percentage to provide better protection. Additionally, national health organizations like the American Academy of Ophthalmology and the American Optometric Association recommend the use of sunscreen or other physical sunscreen protection such as window tinting to help block out the UV radiation.

Ultraviolet (UV) Radiation and Overall Health

Ultraviolet radiation can also be damaging to the skin and immune system, leading to skin cancer and other serious health issues. Exposure to UV radiation can cause DNA damage and suppress the immune system which can lead to an increased risk of infection. Additionally, UV radiation can cause damage to the epidermis, which can lead to premature aging, wrinkles, and pigmentation changes.


Ultraviolet radiation has the potential to cause serious eye damage and health issues. The best way to protect oneself from UV radiation is by wearing sunglasses, wide-brimmed hats, and using sunscreen or other physical screening methods. Additionally, it is recommended to avoid the sun during its peak hours when the UV radiation is the strongest.
