Can a person become blind with hit in the head?

Yes, a person can become blind with a hit in the head. There are a number of ways that this can happen, including:

- Direct damage to the eye itself. A hard blow to the head can cause the eye to rupture, or it can damage the delicate tissues inside the eye, such as the retina or the optic nerve. This can lead to permanent vision loss.

- Swelling around the eye. If there is a lot of swelling around the eye, it can put pressure on the optic nerve, which can lead to temporary or permanent vision loss.

- Bleeding inside the eye. A hard blow to the head can cause blood vessels in the eye to rupture, which can lead to bleeding inside the eye. This can cause blurred vision or, in severe cases, blindness.

- Stroke. A hard blow to the head can also cause a stroke, which is a sudden loss of blood flow to the brain. A stroke can damage the optic nerve, which can lead to vision loss.

Vision loss from a head injury can be temporary or permanent, and the severity of the vision loss will depend on the type of injury and the extent of the damage. In some cases, surgery may be necessary to repair the damage and restore vision.
