# Subtle sign no. 4: You experience blurred vision
In its early stages, diabetes can cause blurred vision. Too high or too low glucose levels can lead to a lack of sharpness in vision. As a general rule, as soon as you stabilize your glucose levels, your vision will get better too.
The real problem with diabetes is when you left it untreated. Your blurry vision caused by diabetes can lead to proliferative retinopathy, which translates to blood vessels leaking into the center of your eyes.
However, blurry vision is not the only eye-related sign of diabetes. You may also experience sensitivity to light or double vision.
