What Are the Possible Causes of Blurred Vision In One Eye?

When you see blurry vision in just one eye, it could be due to several reasons. One possibility is an infection like conjunctivitis, which can make the eye red and vision blurry. This type of infection might happen if viruses or bacteria get into the eye and cause swelling and discomfort. Another cause can be a cataract that develops. Also, changes at the back of the eye, like age-related macular degeneration, can sometimes affect one eye more than the other, leading to blurred central vision. Complications of high blood pressure and diabetes can also blur vision in one or both eyes. When any of these problems occur, they change how light is processed in that one eye. If you notice that one eye is suddenly not as clear as usual, it is very important to visit an eye doctor. They can check your eye and help decide on the best treatment to clear up your vision.
