Did you remember to apply sunscreen today? As skin is the largest organ of the human body, it is hard to ignore the effects of damaging sunlight. However, have you considered the sun’s effects on your eyes? Like the skin, the human eye is exposed to ultraviolet radiation (UVR) from the sun each day. Commonly, individuals believe standard UVR-blocking sunglasses are adequate protection against harmful radiation. However, because these lenses can reduce one’s innate behavioral aversion to bright sunlight and the squint mechanism, they can lead to an increase in a person’s dosage of UVR and result in a “sunburn” effect on the ectoderm tissue of the eye. Some frame styles, though effective at protecting the frontal optical axis, can leave one susceptible to harmful rays that affect the lateral surfaces of the eye. Dr. Jan Bergmanson, professor of optometry in the University of Houston College of Optometry (UHCO) and founding director of the Texas Eye Research and Technology Center (TERTC), has been working with Essilor International, one of the largest lens manufacturers in the world, to improve the eye’s protection against ultraviolet radiation through a rating system for protective lenses.
