Potential Effects of Diabetes on Your Eyesight


Diabetes can harm your eyes over time, resulting in vision loss or blindness. The good news is that managing your diabetes and routine eye checkups by Adelaide eye surgeons can help prevent visual issues and halt their progression.

Diabetes patients are susceptible to developing diabetic retinopathy, macular edema, cataracts, and glaucoma. All these conditions can cause vision loss, but early detection and treatment can greatly improve your chances of protecting your eyesight.

Effect of Diabetes on Your Vision

There are several possible consequences of diabetes, such as-

  • Blurry Vision:

Do not instantly buy new glasses if you are experiencing blurriness in your eyes. It is only a minor issue brought on by high blood sugar. Your lens can swell, which would impair your vision. To fix it, you must bring your blood sugar back to the recommended levels, between 70 to 130 milligrams per deciliter (mg/dL) before meals and less than 180 mg/dL one to two hours after eating. Your vision may not fully reach normal for up to three months.

  • Cataract:

The natural lens in your eye allows it to perceive and focus on a picture, just like a camera. If the lens gets cloudy, a cataract starts to develop. Anyone can get them, but people with diabetes are more likely to get them early and for longer. When a portion of your lens is blurry, your eye cannot focus correctly. You’ll lose vision. Symptoms include glare and impaired vision. Surgery is required to remove a cataract. Adelaide eye surgeons will replace the foggy lens with an artificial one. You can also get an anti-glare sunglass to relieve the symptoms of cataracts. If you can successfully manage the symptoms of a cataract, surgery doesn’t have to be an immediate choice or even necessary.

  • Diabetic Retinopathy:

It is among the most common causes of blindness in working people. High blood sugar damages the retina’s blood vessels, which causes diabetic retinopathy (a light-sensitive layer of cells in the back of the eye). Blood flow may be halted, or eyesight may become fuzzy due to swollen, leaking, damaged blood vessels. New blood vessels can occasionally form, but they aren’t always healthy and can worsen existing visual issues. Both eyes can be affected by diabetic retinopathy.

  • Glaucoma:

Glaucoma can occur in various ways or forms; it is more common in people with diabetes. When fluid cannot drain properly from your eye, pressure builds up inside it. In addition to nerve and blood vessel damage, vision changes may result from this. The most prevalent type, open-angle glaucoma, is treatable with medication. They ease eye strain, hasten drainage, and lessen ocular fluid production. Diabetes is a contributing factor in neovascular glaucoma. The blood vessels in the retina may become damaged by high sugar levels, or aberrant new blood vessels may form. The coloured area of the eye, the iris, can develop new blood vessels, raising eye pressure and leading to glaucoma.

  • Swollen eye lens:

Diabetes might also cause the eye lens to enlarge, resulting in hazy vision. Your eye’s lens may change shape, and your vision may become blurry if your blood sugar levels go from low to normal quickly. After your blood sugar levels have stabilised, your vision returns to normal. To acquire the most precise glasses prescription, controlling your blood sugar levels before your eye exam is crucial.

Manage your diabetes ABCs (A1c, blood pressure, cholesterol), stop smoking if you smoke, and maintain healthy blood sugar levels to prevent or slow the progression of eye diseases.

It’s best to start managing your diabetes and other health concerns as soon as possible. Taking better care of yourself now helps safeguard your eyes for the future.

When to Call the Doctor?

If you experience any of the following symptoms, then consult an Adelaide eye surgeon as soon as possible –

  • Black spots in your vision
  • Light flashes in your vision
  • Holes in your vision
  • Blurry vision

There are usually no symptoms at the early stages of diabetic eye disease. When damage starts to occur inside your eyes, especially with diabetic retinopathy, you might not even experience any pain or changes in your vision. However, if you have diabetes, visit an Adelaide private hospital for regular eye checkups.


Diabetes has an overall impact on your body. Most people are aware that having diabetes raises your chance of developing heart disease and stroke, but many are not aware that it can also impair your vision. Therefore, to maintain your eye health and detect the various problems early on, visit Adelaide private hospital for routine comprehensive eye checkups.
