Itsy bitsy contact lenses

Even in the summer, I rarely wear sunglasses, although I have in recent years purchased big giant ones that cover about 1/3 of my face and just place them over my regular glasses (I wear trifocals). Research done at Ohio State shows we should wear them even in the winter, and if you wear contacts, you can have UV blocking lenses. Little rabbits wore them to test their effectiveness. I don't even want to know how they found out they were or weren't affected. (But if you read the original, it will tell you.) From OSUToday:

"Heather Chandler, PhD, assistant professor, and a group of researchers from The Ohio State University College of Optometry found that UV blocking contact lenses protect the eyes from harmful UV rays.

According to the article (“Prevention of UV-Induced Damage to the Anterior Segment Using Class I UV Absorbing Hydrogel Contact Lenses”), 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.

“Unfortunately, people are generally unaware of when their eyes are at greatest risk for damage from UV exposure,” said Dr. Chandler. “This research involving UV-absorbing contact lenses can provide another option for protection against the detrimental changes caused by UV.

The study exposed rabbits daily to the equivalent of about 16 hours of exposure to sunlight in humans — enough to induce UV-associated corneal changes. The rabbits who wore UV-absorbing contact lenses (Senofilcon A) were not affected by the UV exposure."

Looks like I should be paying more than five bucks for my sunglasses, too. Yes, and we should be wearing sunblock year around, however, in Ohio, we are so thrilled to see sunshine, we rarely think about blocking it.
