Decades of research have shown that both motion processing and pursuit eye movements are affected by age; it follows that older adults may also be less sensitive to depth from motion parallax.

Why is my depth perception bad at night?

Speaking of which, if you have persistent problems with depth perception, particularly at night, you should check with your eye doctor to make sure it isn’t a symptom of a larger issue.

What is secondary vision?

“Second sight” refers to a temporary change in vision during early cataract development. Before vision deteriorates, vision, especially close-up reading vision, improves significantly.

What does bad depth perception look like?
