When we say that we have blurred vision this usually means that our vision is not sharp thus we are unable to see the fine detail. For example, when we are watching a movie we can make out the actor’s face but unable to make out the eyes or the shape of the mouth of the actor.
Depending on the cause blurred vision can occur suddenly or gradually. It can affect both or only one eye. It can persist or disappear and later recur.
