Question

You need saccadic eye movements when you are reading this sentence in order to:

a) Maintain steady fixation on the text.
b) Constrict your pupils for better focus.
c) Process peripheral visual information.
d) Adjust the lens curvature for near vision.

Answer 1

Saccadic eye movements are required for maintaining steady fixation on the text while reading, as they allow the eyes to quickly jump from word to word.

Step-by-step explanation:

You need saccadic eye movements when you are reading this sentence in order to maintain steady fixation on the text. Saccadic movements are rapid, conjugate movements of the eyes that help in quickly scanning visual stimuli, such as text on a page or a screen.

Saccadic eye movements are required for maintaining steady fixation on the text while reading, as they allow the eyes to quickly jump from word to word.

This allows us to focus on different words and move along the sentence efficiently. While doing so, saccades are not involved with adjusting the lens curvature for near vision, which is called accommodation, nor are they responsible for pupil constriction or processing peripheral visual information.
