>I just came up from a dive and one of my eyes has a bright red spot on it. What could cause this? Do I need to see an eye doctor?
>The most common cause of a red spot on the eye after a dive is a subconjunctival hemorrhage. This is a collection of blood over the sclera (white part) of the eye. It is usually caused by a mild mask squeeze and does not require any treatment. A more severe squeeze could result in other injuries to the eye, however, so it is a good idea to see your eye doctor just in case. It is absolutely essential to see your eye doctor if you have eye pain, double vision, blind spots in your field of vision, or decreased vision after a dive or if you have a history of eye surgery in the past.
