Question

Accommodation refers to the

a. diminishing sensitivity to an unchanging stimulus
b. quivering eye movement that enables the retina to detect continuous stimulations
c. process by which stimulus energies are changed into neural messages
d. process by which the lens changes shape to focus images on the retina

Answer 1

Accommodation in vision is the process where the eye's lens changes shape to focus on objects at various distances, which is necessary for clear vision.

Step-by-step explanation:

The term accommodation in vision refers to the process by which the lens changes shape to focus images on the retina for clear vision across different distances. This adaptation of focal power enables a real image to be projected onto the retina, regardless of whether the visual stimulus is near or far.

Accommodation is a crucial function of the eye and involves the coordination of the skeletal muscles for convergence and the smooth muscles of the ciliary body to adjust the lens, referred to as the accommodation-convergence reflex. Over time, as accommodation ability changes with age, corrective lenses may be required to aid in focusing on closer objects.
