3Blurred Vision
Blurred vision is a very common eye issue. Any problem with the optic nerve, retina, or cornea, would lead to sudden blurry vision. People with glaucoma would experience this symptom. However, it tends to occur over the long run rather than suddenly after a single event. Blurred vision would affect how you see and look. The symptom is quite like wearing a filter over the eyes, which makes surroundings look dim and clouded. Everything seems to be not in focus as well. Some cases can affect parts of the vision, while others might have effects on the whole line of sight. [3]
