Many people think their eyesight is just fine, but then they get that first pair of glasses or contact lenses and the world comes into clearer view—everything from fine print to street signs.
Improving your eyesight is important—about 11 million Americans over age 12 need vision correction—but it’s just one of the reasons to get your eyes examined. Regular eye exams are also an important part of finding eye diseases early and preserving your vision.
Eye diseases are common and can go unnoticed for a long time—some have no symptoms at first. A comprehensive dilated eye exam by an optometrist or ophthalmologist (eye doctor) is necessary to find eye diseases in the early stages when treatment to prevent vision loss is most effective.
During the exam, visual acuity (sharpness), depth perception, eye alignment, and eye movement are tested. Eye drops are used to make your pupils larger so your eye doctor can see inside your eyes and check for signs of health problems. Your eye doctor may even spot other conditions such as high blood pressure or diabetes, sometimes before your primary care doctor does.
Early treatment is critically important to prevent some common eye diseases from causing permanent vision loss or blindness:
● Cataracts (clouding of the lens), the leading cause of vision loss in the United States
● Diabetic retinopathy (causes damage to blood vessels in the back of the eye), the leading cause of blindness in American adults
● Glaucoma (a group of diseases that damages the optic nerve)
● Age-related macular degeneration (gradual breakdown of light-sensitive tissue in the eye)
Of the estimated 93 million US adults at high risk for vision loss, only half visited an eye doctor in the past 12 months. Regular eye care can have a life-changing impact on preserving the vision of millions of people.
Though people tend to have more vision problems as they get older, children need eye exams to ensure healthy vision, too. But only 39% of preschool children have had their vision tested, which is needed to diagnose eye diseases.
Amblyopia (reduced vision because the eye and brain aren’t working together properly) is the most common cause of vision loss in children—2 to 3 out of 100 children. Amblyopia needs to be treated promptly to help avoid vision loss.
● Children's eyes should be checked regularly by an eye doctor or pediatrician. The US Preventative Services Task Force recommends vision screening for all children at least once between age 3 and 5 years to detect amblyopia or risk factors for the disease.
● People with diabetes should have a dilated eye exam every year.
● Some people are at higher risk for glaucoma and should have a dilated eye exam every 2 year:
● African Americans 40 years and older
● All adults older than 60, especially Mexican Americans
● People with a family history of glaucoma
If you have any of the following eye problems, don’t wait for your next appointment—visit your eye doctor as soon as possible:
● Decreased vision
● Draining or redness of the eye
● Eye pain
● Double vision
● Floaters (tiny specks that appear to float before your eyes)
● Circles (halos) around lights
● Flashes of light
Diabetic retinopathy is a common complication of diabetes. High blood sugar damages the blood vessels in the retina (a light-sensitive part of the eye), where scarring can cause permanent vision loss.
Diabetic retinopathy is also one of the most preventable causes of vision loss and blindness. Early detection and treatment can prevent or delay blindness due to diabetic retinopathy in 90% of people with diabetes, but 50% or more of them don’t get their eyes examined or are diagnosed too late for effective treatment.
People with diabetes are also at higher risk for other eye diseases, including glaucoma and cataracts. If you have diabetes, an eye exam every year is necessary to protect and preserve your eyesight and eye health.
Due to our aging population, the number of blind and visually impaired people in the United States is estimated to double by 2030 and triple by 2050. Encouraging people to take care of their vision health as part of their overall health and wellness could significantly reduce that number and improve quality of life for millions of Americans.

If you spend a lot of time focusing on one thing, such as a computer screen, your eyes can get tired. Try the 20-20-20 rule to reduce eyestrain: every 20 minutes, look away about 20 feet in front of you for 20 seconds.
