Diabetes and Your Eyes: What You Should Know

Diabetes affects millions of people in the UK, and one of its most significant complications involves the eyes. Diabetic eye disease is a leading cause of preventable sight loss among working-age adults, yet with proper monitoring and management, much of this vision loss can be avoided.

High blood sugar levels over time can damage the tiny blood vessels in the retina, the light-sensitive layer at the back of the eye. This condition, called diabetic retinopathy, develops gradually and often without obvious symptoms in its early stages. By the time vision is noticeably affected, considerable damage may have occurred.

The good news is that diabetic retinopathy can be detected long before it affects your sight. This is why everyone with diabetes is invited for annual diabetic eye screening through the NHS. This screening looks specifically for signs of diabetic changes in the retina.

However, screening focuses only on diabetic retinopathy. People with diabetes are also at increased risk of other eye conditions, including cataracts and glaucoma. A full eye examination assesses all aspects of eye health, complementing the diabetic screening programme.

Keeping blood sugar levels well controlled is the single most important thing you can do to protect your eyes. Blood pressure and cholesterol management matter too, as these factors affect blood vessel health. Not smoking, maintaining a healthy weight, and staying physically active all contribute to reducing risk.

If you have diabetes, don't skip your annual screening appointments. If you notice any sudden changes in your vision, such as new floaters, flashing lights, or sudden blurring, seek urgent attention. These could indicate more advanced problems that need prompt treatment.
