Question

Quizplus · Accepted Answer

Refraction, convergence, pupillary constriction, and accommodation are all eye functions responsible for maintaining clear images of objects. Refraction bends light rays to focus them on the retina, convergence aligns both eyes to focus on the same object, pupillary constriction adjusts the amount of light entering the eye, and accommodation changes the lens shape to focus on objects at different distances. Lubrication, while important for eye health, does not directly contribute to the clarity of images.
