Experts recommend that everyone get a regular eye check up, and two local medical entities are hosting eye screenings for those who can't afford them otherwise.

Through the University of Arizona College of Medicine, the Sight Savers program, medical students are able to provide those who are under-insured or who don't have health insurance with free eye screenings.

"We specifically target communities of people, who are under-insured, don't have insurance or don't have the means to afford care," said Trent Bowen, coordinator of the UA's Sight Savers program. "People can partake in these free eye screenings by calling the UA's Department of Ophthalmology...and they can make an appointment to come to St. Elizabeth's (Health Center)."

He said Sight Savers visit St. Elizabeth's the third Saturday of every month.
