Question

multiple choice 2 points

which of the following is not considered an optical component of the eye?

cornea

vitreous body

retina

lens

aqueous humor

Explanation:

Define optical components of the eye

The optical components of the eye are the transparent media that admit light, bend (refract) light rays, and focus images on the retina. These components include the cornea, aqueous humor, lens, and vitreous body.

Identify the non-optical component

The retina is not an optical component; rather, it is a neural component. It contains the photoreceptors (rods and cones) and neural circuitry that convert light energy into electrical signals to be sent to the brain.

Evaluate the given options

• Cornea: Transparent anterior cover that refracts light. (Optical)
• Vitreous body: Transparent jelly filling the posterior cavity. (Optical)
• Retina: Neural layer containing photoreceptors. (Neural, not optical)
• Lens: Transparent structure that adjusts focus. (Optical)
• Aqueous humor: Clear fluid in the anterior and posterior chambers. (Optical)

Answer:

• Cornea
• Vitreous body
• Retina (Correct answer)
• Lens
• Aqueous humor
