A new study reported in Investigative Ophthalmology & Visual Science found that UV-blocking contact lenses can reduce or eliminate the effects of the sun’s harmful UV radiation.
According to the article, “Prevention of UV-Induced Damage to the Anterior Segment Using Class I UV Absorbing Hydrogel), overexposure to UV radiation can lead to harmful changes in the cornea, conjunctiva and lens, including cataracts, the most common cause of visual impairment around the globe. According to the researchers, some estimates say that by the year 2050, there will be 167,000 to 830,000 more cases of cataracts.
Dr Ashraf adds that UV light exposure not only puts your skin at risk but also the eyes. Certain eye diseases have been implicated to UV exposure including cataracts, pterygium, and macular degeneration. This study shows that UV blocking contact lenses are beneficial in decrease your risk to UV exposure to the eye. In patients that do not wear contact lenses, such as ones that had LASIK surgery, good UV blocking sunglasses and hats also aid in decreasing UV light exposure. Dr Ashraf adds that these preventative measures are important not only in the summer but also during winter activities such as skiing in which the sun light gets reflected off the snow and can enter the eye.
