People ages 20 to 30 should have an eye exam every two years, unless visual changes, pain, flashes of light, new floaters, injury, or tearing occurs. Then, immediate care is necessary.
Yearly exams become important in the late thirties when changes in vision and focus along with eye diseases are more likely to develop. People with diabetes are at risk for several eye disorders, including diabetic retinopathy, glaucoma, and cataracts, and should have eye examinations every year.
Squinting, blinking, rubbing eyes frequently, headaches, changes in vision and difficulty with visual concentration within arm's length may be signs of eye problems and should be checked immediately by your optometrist.
When it comes preserving your vision, early detection is the solution.
