DeKALB – Eyes get old, just like other parts of the body, but people can take steps to preserve vision.

“Eventually, we all develop cataracts,” said Dr. James Dillon, a Northern Illinois University expert on eyes. At the next STEM Cafe, Dillon will speak on how the eye changes with age and what people can do to slow the deterioration of vision. His talk, "For Your Eyes Only," will be held at 6:30 p.m. Tuesday, March 26 at Eduardo's Restaurant, 214 E. Lincoln Highway in DeKalb.

In addition to explaining the amazing biological process that allows us to see, Dr. Dillon will share practical advice on protecting the eyes. For instance, he says that many sunglasses on the market today do not provide protection from ultra-violet rays, which can harm vision. He will also discuss changes in vision before and after cataract surgery.
