Over time, high blood sugar can damage the tiny blood vessels in your retina, the part of your eye that senses light. That can lead to swelling in a part of the retina called the macula, new and unwanted blood vessels growing in the eye, and bleeding inside the eye.

Complications that can arise from strabismus include blurry vision, eye strain, fatigue, headaches, poor three-dimensional vision, and double vision. A lazy eye may also develop, which happens when the brain receives two images from eyes looking in different directions. In an effort to avoid double vision, the brain may ignore what the turned eye sees, causing poor vision development in that eye. High blood sugar levels cause fluid to move into your eyes, which can create swelling in the lenses. The swelling changes the shape of your eyes, which results in temporary blurred vision.

Eye allergies

A doctor can provide more details about what a person can do to address their vision issues.

If a person experiences a more severe detachment, surgery may be necessary to move the retina back into place and reattach it. Cloudy blurry vision after drinking alcohol vision, or hazy vision, also means that you can’t see things clearly. However, it doesn’t happen because things are out of focus.
