Many people think of eye problems as something that happens to older people, but in fact, there are many eye conditions that can affect people in all stages of life — even childhood.

Some of the eye conditions that can threaten a child's vision are hard to detect, so children should have an eye and vision screening before age 5.

Early detection and treatment of childhood eye conditions such as strabismus and amblyopia can help ensure a lifetime of good vision.

Most young adults have healthy eyes, but accidental injury is one of the leading causes of vision loss in this age group.

Sports, yard work, harsh chemicals — even jump-starting a car — can be hazardous to the eyes. Make sure you always wear the appropriate protective eyewear during these activities.

Some of the eye problems that harm the vision of older people actually start much earlier. Many of them can be effectively treated and vision preserved if caught early enough. Ask your Eye M.D. if you may be at risk for problems like glaucoma or diabetic eye disease, and how often you should have an eye exam.

Some vision changes are natural as we get older. Most of these can be adequately corrected with glasses, contacts or refractive surgery. However, sudden or frequent changes may signal a problem and should prompt a visit to the Eye M.D.

Because seniors are at increased risk for serious eye problems, they should have more frequent eye exams. Please check with your Eye M.D. about a schedule that is right for you.

In general, from ages 40 to 64, you should have an eye exam every two to four years. After age 65, you should increase that to once every one to two years, and even more frequently if your Eye M.D. recommends it.

People sometimes accept eye problems like decreasing or cloudy vision, or dry or teary eyes as an unavoidable condition of aging. Most of these problems, however, can be corrected and improved with the right treatment. Talk to your Eye M.D. if you have any eye problem that bothers you.

Even if poor vision can't be improved, you can still enjoy an active and independent lifestyle. Many Eye M.D.s offer low vision rehabilitation or can refer patients to these services.
