Your aging eyes

You may barely notice the changes at first. Maybe you've found yourself reaching more often for your glasses to see up close. You might have trouble adjusting to glaring lights or reading when the trouble light is dim. You may even have put on blue socks thinking they were black. These are some of the normal changes to your eyes and vision as you age.

As more Americans head toward retirement and beyond, scientists expect the number of people with age-related eye problems to rise dramatically. You can't prevent all age-related changes to your eyes. But you can take steps to protect your vision and reduce your risk for serious eye disease in the future. Effective treatments are now available for many disorders that may lead to blindness or visual impairment. You can also learn how to make the most of the vision you have.

"Vision impairment and blindness are among the top 5 causes of disability in older adults," says Dr. Cynthia Owsley, an eye researcher at the University of Alabama at Birmingham. Vision changes can make it difficult to perform everyday activities, such as reading the mail, shopping, cooking, walking safely and driving. "Losing your vision may not be life-threatening, but it certainly affects your quality of life," Owsley says.

The clear, curved lens at the front of your eye may be one of the first parts of your body to show signs of age. The lens bends to focus light and form images on the retina at the back of your eye. This flexibility lets you see at different distances—up close or far away. But the lens hardens with age. The change may begin as early as your 20s, but it can come so gradually it may take decades to notice.
