Mamy people choose to kick off the new year with clearer vision...the thought of throwing those glasses away for good is so appealing. Are you considering LASIK?
Good thing we have eyelashes...one of the duties of our eyelashes is to protect our eyes from foreign objects. However, some foreign objects seem to slip right by them. Can you imagine how many things would get into your eyes if you didn't have eyelashes?
If something does happen to find its way into your eye, do you know how to get it out?
Contact lenses are being developed that could provide a continuous supply of anesthetic medication to the eyes of patients who undergo laser eye surgery - an advance that could relieve patients of the burden of repeatedly placing drops of medicine into their eyes every few hours for several days. The research report appears in ACS' journal Langmuir.
Researchers tested whether anesthetics loaded onto this type of lens could release the drugs over time automatically. They found that adding vitamin E to the lenses extended the time of release of three commonly used anesthetics from just under two hours to up to an entire day - or a few days in some instances. The vitamin E acts as a barrier, keeping the anesthetics on the eye, right where they are needed.

A new study published in Free Radical Biology and Medicine suggests that eating grapes can slow or help prevent the onset of age-related macular degeneration (AMD). AMD is a debilitating eye disease that affects millions of elderly people worldwide.
The antioxidants in grapes may be responsible for the protective effects. "The protective effect of the grapes in this study was remarkable, offering a benefit for vision at old age even if grapes were consumed only at young age," said principal investigator Silvia Finnemann, PhD, Department of Biological Sciences, Fordham University in New York.
Note to self: Eat more grapes.
