Most of the time, if you see blurry, it’s a sign of fatigue. However, it can also indicate certain ophthalmological disorders.
Depending on the problem, blurred vision can occur in one or both eyes, and it can affect a part of the vision or the entire visual field.
Find out what causes blurred vision and how it is treated.
