When you are in the dark, your eyes adjust to low light by dilating the pupils to let in more light. This can cause the red color of blood vessels in the back of your eye to become more visible, giving the appearance of red vision.

What causes red vision in the dark and how can it be treated or prevented?

Red vision in the dark is caused by the presence of a high number of blood vessels in the eye, which become more visible in low light conditions. This can be a normal physiological response and is not usually a cause for concern. To prevent or reduce red vision in the dark, it is important to ensure adequate lighting in the environment and to give the eyes time to adjust to the darkness before moving around. If red vision persists or is accompanied by other symptoms, it is recommended to consult with an eye care professional for further evaluation and treatment.
