Effect of diabetes on the eyes

Can diabetes affect your eyes?

Yes. Diabetes can negatively affect your vision. If you have high blood sugar, your vision may become blurry. You may experience cataracts, glaucoma or retinopathy. In severe cases, diabetes can even make you lose your sight.

Blurred Vision

If you notice your vision getting blurry and you already have diabetes, see a doctor to make sure that it is your diabetes causing this. To prevent your vision from getting permanently blurred, your blood sugar needs to be regulated and come back into the normal range.


Anyone can potentially get cataracts but if you have diabetes, the chances are much higher. Cataracts cloud your eyes with debris. This can cause blurred vision and glare. Cataracts can only be removed with surgery. Your cloudy lens gets replaced with an artificial one.


When the pressure inside your eye builds up, your eyes cannot drain fluid like it normally can. This can damage your blood vessels and nerves and cause poor vision. There are some medications that can treat open-angle glaucoma. Open-angle glaucoma is the most common type of glaucoma. This type of glaucoma does not cause significant symptoms until you have vision loss. This is why you need regular eye checkups to catch this sort of thing. Other forms of glaucoma come with their own set of symptoms like:

  1. Headaches
  2. Eye pain
  3. Blurry vision
  4. Vision loss
  5. Halos around lights
  6. Watery eyes

Treatment can include eye drops and medicine. You might even need surgery and laser treatment to get rid of the drainage.

You may even develop neovascular glaucoma. In this type of glaucoma, new blood vessels grow on the iris. This again blocks the normal flow of fluid and raises the eye pressure.glasses Mira Sunglasses

This can be very difficult to treat. Laser surgery and implants can help drain the fluid and cut the vessels.

Diabetic Retinopathy

If there is any damage to the small blood vessels in your retina, it can cause diabetic retinopathy. This is extremely serious. If not treated in time, you could go blind. The only way to prevent this from happening is to keep your blood sugar levels low.

Diabetic retinopathy has other subsets like –

  • Background retinopathy: This is the starting point. Your vision is still okay but your blood vessels are damaged. This is manageable if you keep your blood sugar levels in control.
  • Maculopathy: An important part of your retina, the macula, can get damaged in this condition. Your vision is greatly affected because of this.
  • Proliferative retinopathy: When calls at the back of your eye do not get enough oxygen, new blood vessels start to grow. These blood vessels are fragile and can bleed easily leading to a clot. This can lead to scars pulling your retina away from the back of your eye. This is an extremely serious condition. If your retina gets detached, there is nothing anyone can do. If it is caught in time, surgery can fix the issue.

If you have diabetes, make sure to visit your doctor frequently to keep these problems at bay. Even with diabetes, you can wear colored lenses like Bella Sandy Gray or Brown Shadow Bella as long as your doctor signs off on it.
