Quizplus · Accepted Answer

The optic disk is the point on the retina where the optic nerve exits the eye. This is the location of the blind spot in the visual field, where there are no photoreceptor cells. A lacrosse injury could damage the optic disk, which would make the blind spot more evident. The fovea is responsible for sharp, clear central vision, the lens helps to focus light onto the retina, and the cornea helps to protect the eye and refract light. None of these structures are directly involved with the blind spot.
