Question

both retinal disparity and convergence increase as an object gets closer to the individual.

please select the best answer from the choices provided

t
f

Explanation:

Analyze retinal disparity

As an object moves closer to the eyes, the difference between the images projected onto each retina (retinal disparity) increases because of the greater angle between the line of sight of each eye.

Analyze convergence

As an object gets closer, the eyes must turn inward (converge) more to keep the object focused on the fovea, which increases the physical tension in the extraocular muscles.

Evaluate the statement

Since both retinal disparity and convergence increase as an object gets closer, the statement is true.

Answer:

• (A) T (Correct answer)
• (B) F
