Type 2 diabetes is a lifelong condition that causes a person’s blood sugar level to become too high. Blood sugar levels rise due to a dysfunction in the way insulin, a hormone that regulates high blood sugar, is released. If the pancreas does not produce enough insulin or the body’s cells do not react to insulin, blood sugar levels have free rein, and this could cause a harrowing effect to one’s eyes. Experiencing either blurred vision or floaters could mean your blood sugar levels are too high.
Blurred vision is one of the earliest warning signs of diabetes, warned Specsavers’ clinical spokesman, Dr Nigel Best.
Those most at risk are people whose vision swaps between blurry and perfectly normal.
It’s caused by blood sugar levels being unstable, Best exclusively told Express.co.uk.
“Fluctuating blurred vision is the main symptom people with diabetes get in their eyes,” he said.
“People may find that one day they have blurred vision but another day they can see perfectly fine, this is down to their sugar levels not being stable.”
Blurred vision is also a warning sign of diabetic retinopathy, a complication caused by damage to the blood vessels at the back of the eye.
Diabetes patients are more at risk of developing blurred vision and changes to the eyes, according to Ophthalmic Consultants of London’s retinal surgeon, Mr Shahram Kashani.
When the condition is advanced, it can cause abnormal blood vessels to develop at the back of the eye.
These can lead to a number of complications, including floaters.
Floaters are dark spots in your vision that may appear as black or grey specks or strings.
