A staggering one in 25 people in the UK have diabetes and this is on the rise as the country faces an obesity crisis.

What is diabetes?

Diabetes is caused by a lack of insulin in the body, leading to an increased blood sugar level.

But did you know that diabetes can have a long-lasting effect on all areas of the body including the eyes, and is the leading cause for blindness in the UK?

An eye test can reveal signs and symptoms of diabetes and its associated complications that have otherwise gone undetected. These complications include diabetic retinopathy, a condition that if left untreated can cause damage to vision.

Amazingly, according to the NHS, approximately 90 per cent of diabetes-related blindness could be avoided by getting an annual eye exam.

Eye tests can detect diabetes

What are some of the most common symptoms of diabetic retinopathy?

  • Blurred or double vision,
  • Unusual flashing lights,
  • Dark floating spots in one or both eyes,
  • Blank spots or streaks of red in the field of vision,
  • Scope of vision changing from day-to-day or even from morning to evening,
  • Decrease in depth perception,
  • Decrease in visual sharpness.


Diabetic retinopathy often doesn’t have any noticeable symptoms in the early stages. So, whether you’re suffering from any symptoms or not, it’s always advisable to get attend regular eye tests. 

What can I do to help avoid diabetes?

  • Get plenty of sleep,
  • Eat a balanced and healthy diet,
  • Exercise on a regular basis,
  • Take any medications prescribed to you,
  • Visit a doctor as and when needed.
