A recent Q&A article released by The National Eye Institute (NEI) addresses some common questions and answers about the effects of UV light on the eyes. This informational piece may serve as a helpful resource for optometry patients who wish to better understand how to protect their eyes from the sun.
Several eye problems are linked to UV exposure. Among these, a pinguecula is a protein and fat deposit in the white part of the eye (sclera). It can cause irritation and, in rare cases, affect how tears cover the eye. A pterygium (Surfer’s Eye) is a growth that extends from the sclera to the clear tissue called the cornea, which covers the iris and pupil. Prolonged exposure to UV rays modifies lens proteins, leading to cataract formation and worsening eyesight. Some studies have also suggested prolonged exposure to UV rays without protection increases the risk for AMD.
Among the questions answered are:
- What is UV light?
- Why do I need to protect my eyes from UV light?
- How do I protect my eyes from UV light?
- What eye problems are linked to UV light exposure?
- How can I protect my children’s eyes from UV?
- How do sunglasses work?
- How do I choose a pair of sunglasses?
- Should I avoid cheaper sunglasses?
- Do contact lenses provide UV protection?
The article also dives into greater detail on helpful tips for choosing UV protective sunglasses. Considerations for choosing sunglasses are also mentioned, such as lens material, fit and usage.
