Certified Ophthalmic Assistant Practice Exam

In an accommodated emmetropic eye, parallel light rays from a distance source are focusing precisely on the retina. This means that the lens of the eye has adjusted its shape to ensure that the light converges directly onto the retina, which is essential for clear vision. Therefore, option D, "on the retina," is the correct answer. Options A and B can be eliminated because if the light focused either behind (A) or in front (B) of the retina, this would result in a refractive error (either hyperopia or myopia). Option C, "on the cornea," is incorrect because the cornea plays a role in the eye's focusing system, but it is not the final destination for the focused light rays. The ultimate goal is to have the light rays converge onto the retina for optimal vision.
