Type 2 diabetes means a person either resists the effect of insulin, a hormone that regulates the movement of sugar into the cells, or doesn’t produce enough insulin to maintain normal glucose levels. Left untreated, the high blood sugar could affect various cells and organs in the body. Complications could include kidney damage, often leading to dialysis, eye damage, which could result blindness or an increases risk for heart disease or stroke. Spotting the early signs is vital and there is one major early warning that lies in a persons eyesight.

Normally after a person eats or drinks, the body will break down sugars from the food and use them for energy in the cells.
To accomplish this, the pancreas need to produce a hormone called insulin.
Insulin is what facilitates the process of pulling sugar from the blood and putting it in the cells for use, or energy.
When a person has type 2 diabetes, the insulin can’t be used effectively.
This allows blood glucose levels to rise while the rest of the cells are deprived of much-needed energy.
This can lead to a wide variety of problems affecting nearly every major body system, including the eyes.
When blood sugar levels are high it can lead to problems like blurry vision, cataracts, glaucoma and retinopathy. In fact, diabetes is the primary cause of blindness in adults aged 20 to 74. The damaged blood vessels in the eyes causes visual disturbances like floaters and left untreated, this can lead to blindness.
High blood sugar causes the lens of the eye to swell, which changes the ability to see.
To correct this kind of blurred vision, a person will need to get their blood sugar back into the targeted range.
Blurry vision is often one of the first warning signs of type 2 diabetes.
A person’s vision may be blurry because fluid is leaking into the lens of the eye and this makes the lens swell and change shape.

What is diabetic retinopathy?
Diabetic retinopathy is a term that describes retinal disorders caused by diabetes.
Some of these disorders include macular edema and proliferative retinopathy.
The NHS added: “Diabetic retinopathy is a complication of diabetes, caused by high blood sugar levels damaging the back of the eye.
“It can cause blindness if left undiagnosed and untreated.
Type 2 diabetes can be effectively managed when caught early.
To minimise the risk of the condition a person should ensure their blood sugar levels are under control by managing their diet and lifestyle properly.
Attending a diabetic eye screening is an annual screwing offered to all people with diabetes and to help treat any problems early on.
