What is the consequence of having poor contrast sensitivity?

Having poor contrast sensitivity primarily impacts a person's ability to distinguish objects from their backgrounds. This means that individuals may struggle to identify items that do not stand out well against certain environments, particularly if the colors are similar or the lighting is poor. For instance, a person with diminished contrast sensitivity might find it challenging to see a dark object on a dark surface or a light-colored item in bright lighting. Contrast sensitivity is essential for daily visual tasks, including reading, driving, and navigating spaces, making it a critical aspect of overall visual function.

The other options do not accurately reflect the implications of poor contrast sensitivity. While depth perception and visual acuity are important aspects of vision, they are separate from contrast sensitivity. Enhanced visual timelines do not pertain to contrast sensitivity and instead relate to temporal aspects of visual processing.
