Many variations of vision problems can be a chief indicator for a health issue. Different forms of visual impairment can be found among patients who have diabetes. Without treatment, they can even go blind. Hence, the eye is definitely related to the sugar level in the blood. Hypoglycaemia is often associated with visual disturbances. The visual symptoms during acute hypoglycemia may be caused by some metabolic disturbances in visual pathways in the central nervous system or by impairment in either the crystalline lens, cornea, or even the vitreous humor, collectively termed the eye's refractive apparatus.
The patient may lose their color vision to a considerable extent. And there could be a breakdown of contrast sensitivity. Rapid decreases in blood glucose levels have been correlated with diplopia and blurred vision. Double vision (diplopia) is a condition in which we see the object we are looking at twice. It is caused by strabismus, which is when the eyeballs are not aligned. Hence, different eyes vision problems may occur in a hypoglycaemic patient. Even though these aspects are not characteristic of the hypoglycaemic status, subtle visual dysfunction is present in the majority of patients. Hence, if we are looking for vision changes, we can indicate a low blood sugar state early.
