Your eyes are your window to the world. They are also indicative of changes in your body and probably the need for medical intervention.

Vision changes may mean your blood sugar is high. High blood sugar draws more fluid into the lens of the eye, so your vision is less sharp. The first thing to do is to check your blood sugar more frequently and bring it under better control. Temporary blurriness may also occur when starting insulin.

(Don’t rush to your friendly neighbourhood spectacle store. Some of them are not educated enough and the others plain crooks. They may just con you into a costly new pair when you may really not need one. So don’t hurry. This almost happened to me).

Here’s what you should do

In case the problem continues despite having got your glucose numbers to healthy levels, reach out to your doctor. Eyesight changes may be caused by an easy-to-fix problem like dry eyes; it could be a side effect of some medications or even computer eye strain.

Most importantly it can be a warning sign of diabetic retinopathy – when tiny blood vessels at the back of the eye swell and leak. It could also be a sign of other vision issues like glaucoma or age-related macular degeneration. All can be treated to prevent further problems.

Diabetic Retinopathy

Diabetic retinopathy you should know is a diabetes complication that affects our eyes. It’s caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness.

The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.


As the condition worsens, diabetic retinopathy symptoms may include:

  • Blurred vision
  • Spots in your vision
  • Fluctuating vision
  • Empty areas in your vision
  • Impaired colour vision
  • Vision loss

Diabetic retinopathy usually affects both eyes. Your eye-doctor is the right person to reach out to during such occurrences.
