    Yes. You should plan to make regular eye doctor visits when you have diabetes. High blood sugar can lead to problems like blurry vision, cataracts, glaucoma, and retinopathy. In fact, diabetes is the primary cause of blindness in adults ages 20 to 74.

    Blurry Vision

    Don't buy new glasses as soon as you notice that things look blurry. It could just be a small problem caused by high blood sugar. Your lens could swell, which changes your ability to see.

    To correct it, you need to get your blood sugar back into the target range (70-130 milligrams per deciliter, or mg/dL, before meals, and less than 180 mg/dL 1 to 2 hours after a meal). It may take as long as 3 months for your vision to fully get back to normal.

    Do tell your eye doctor. She can let you know if this is a symptom of a more serious problem.


    The lens allows your eye to see and focus on an image, just like a camera. Cataracts cloud your normally clear lens with debris. Anyone can get them, but people with diabetes tend to get them earlier, and they get worse faster.

    When part of your lens is cloudy, your eye can’t focus like it should. You won't see as well. Symptoms include blurred vision and glare.

    You’ll need surgery to remove a cataract. The doctor replaces the cloudy lens with an artificial one.


    Pressure builds up inside your eye when fluid can’t drain like it should. This can damage nerves and blood vessels, and cause changes in vision.

    Medications can treat open-angle glaucoma, the most common form. They lower eye pressure, speed up drainage, and reduce the amount of liquid your eye makes. (Your doctor will call this aqueous humor.)

    This type of glaucoma may not cause any symptoms until it’s further along and you have major vision loss. Your doctor can catch it earlier, during an annual exam.

    With less common forms of the disease, you might notice:
