Whether or not the blurred vision can heal itself after being hit in the eye needs to be determined according to the injury, if the symptoms are mild and belong to transient blurring of vision, it can be healed by itself, if the symptoms are serious, it usually cannot be healed by itself. If the injury is minor, such as corneal epithelial contusion or blunt contusion of the eyeball, and there is no other discomfort, it is usually a transient blurring of vision, which can be cured by itself. If the injury is more serious, such as retinal damage, rupture of the eyeball and hemorrhage in the fundus of the eye, etc., it is usually more difficult to heal on its own, so it is necessary to go to the hospital in time and actively cooperate with the doctor to carry out the relevant treatment, such as medication or surgical treatment. Therefore, if a patient’s vision is impaired after an eye injury, he or she must go to the hospital in time to seek medical treatment as soon as possible.
