Aging eyes bring more than crow's feet and wrinkles. It's what you can't see—the health of your eyes—that is the bigger concern, doctors say. By the age of 40, many people may begin coping with vision problems they didn't have before. These might include dry eyes and presbyopia, or an inability to focus on objects that are close up, and can leave people feeling fatigued and headachy by the end of the workday. Genetics largely determines how our eyes age. But new research suggests that nutrition and environment can lessen some of the risks to eye health and vision. As people get older, "The lens of your eye gradually loses the ability to focus in and out the way it used to," said Julia Haller, ophthalmologist-in-chief at Wills Eye Institute in Philadelphia. "Some people refuse to wear reading glasses…and really fight it. They may hold out a little longer but eventually we all succumb to the inevitable." While we can't win against Mother Nature, some strategies can minimize the damage.
