Diabetes and Your Eye Health: How High Blood Sugar Can Affect Your Vision

Nov 1, 2023 | Eye Health Info

When we think of diabetes, we usually think about how it affects our heart, kidneys, and nerves. But did you know that high blood sugar levels can also have a huge impact on your eyes? Over time, diabetes can cause damage to your eyes, potentially causing vision loss or even blindness. In this blog post, we’ll discuss how diabetes can affect your eye health and share ways to protect your vision. 

The impact of high blood sugar on your eyesight 

If your blood sugar levels are high, it can damage the blood vessels in your retina, which may lead to a condition called diabetic retinopathy. As a result, you might experience blurry vision, dark spots, or even blindness. High blood sugar levels can also cause your eyes to swell and become inflamed, resulting in a condition called diabetic macular edema. 

Diabetes can also increase your risk of developing cataracts and glaucoma. A cataract is a cloudy area in the lens of the eye that can cause blurry vision and sensitivity to light. Glaucoma is a group of eye diseases that damage the optic nerve and can lead to vision loss. Both conditions can be treated with surgery and medication if detected early. 

The importance of regular eye exams 

If you have diabetes and notice any changes in your eyesight, like blurry vision, a sudden increase in eye floaters, or trouble seeing in the dark, make sure to book an eye exam with your eye doctor. Regular eye exams can catch any vision changes or eye conditions early on before they become serious. 

Ways to protect your eye health 

Controlling your blood sugar levels is key to protecting your eye health and preventing conditions such as diabetic retinopathy or diabetic macular edema. You can do this by following a healthy diet, getting regular exercise, taking medications as prescribed, and monitoring your blood sugar levels regularly. 

Additionally, it’s important to wear sunglasses to shield your eyes from the sun’s UV rays. Finally, if you’re a smoker, quitting smoking can lower your risk of developing eye conditions like cataracts or macular degeneration. 

While diabetes can be a scary diagnosis, it’s important to remember that there are steps you can take to protect your eye health and preserve your vision. By getting regular eye exams, keeping your blood sugar levels under control, quitting smoking, and protecting your eyes from the sun, you can greatly reduce your risk of developing eye issues associated with diabetes.
