Diabetes affects more than just blood sugar—it has a major impact on eye health, too. In fact, diabetes is one of the leading causes of vision loss among working-age adults. The good news? Most diabetes-related vision problems can be caught early—and even prevented—with regular eye exams.
High blood sugar levels can damage the tiny blood vessels in your eyes, leading to a condition called diabetic retinopathy. Over time, this can cause:
Blurred or fluctuating vision
Dark spots or “floaters”
Poor night vision
Vision loss if left untreated
Diabetes also increases the risk of other serious eye conditions, including glaucoma and cataracts.
Diabetic retinopathy is a progressive condition that damages the retina—the light-sensitive tissue at the back of the eye. In early stages, there may be no noticeable symptoms, which is why yearly exams are essential.
A comprehensive dilated eye exam allows your eye doctor to detect early changes before symptoms appear. Early treatment can slow or stop the progression of vision loss.
Even if your vision seems fine, an annual exam is crucial if you:
Have Type 1 or Type 2 diabetes
Are prediabetic
Have a history of high blood pressure or cholesterol
Manage your blood sugar, blood pressure, and cholesterol
Quit smoking (it worsens diabetic complications)
Exercise regularly and eat a balanced diet
Get your eyes checked once a year—without fail
Diabetes doesn’t have to mean vision loss. With proper care and annual eye exams, you can protect your sight and stay ahead of serious complications.
Don’t wait for symptoms—early action saves vision.
