Is UV Light Bad for Your Eyes?: A Quick Guide to Protecting Your Vision from UV Rays

UV light, or ultraviolet light, is a form of electromagnetic radiation originating from the sun and certain artificial sources like tanning beds and some fluorescent lights. Prolonged or unprotected exposure to UV light can indeed be harmful to your eyes. The short-term effects may include photokeratitis—essentially a sunburn for the eye—which causes pain, redness, blurred vision, and excessive tearing. Long-term UV exposure significantly increases the risk of cataracts, macular degeneration, and even certain rare cancers of the eye and eyelids. Wearing sunglasses that block 100% of UVA and UVB rays, and using wide-brimmed hats, are both effective ways to reduce UV exposure.

From a designer’s perspective, ensuring spaces—whether residential or commercial—have adequate window treatments, such as UV-filtering window films or blinds, is not only an aesthetic choice but a health one. Thoughtful use of materials and natural light in interior design can help create safer, healthier living environments. When planning your next project, consider how effective room layout and design choices can naturally limit harmful UV exposure, while still maximizing comfort and visual appeal.

Tips 1:

Choose sunglasses labeled as offering “100% UV protection.” Incorporating light-filtering window treatments into your home or office can further reduce the risks of UV-related eye damage.
