Can a hit in the head leave you blind?

A hit to the head does not always lead to loss of eyesight, but there are scenarios where significant traumatic injuries can cause retinal detachment or optic nerve damage that may result in loss of vision or significant visual impairment. The consequences depend on the location and severity of the impact and individual differences in anatomy and response to injuries. If a head injury has occurred, seeking prompt medical attention is crucial to evaluate and properly manage any potential impacts on eyesight.
