What this helps track

Low-contrast vision assessments use guided on-screen tasks with reduced contrast letters and shapes to help track subtle changes in visual sensitivity over time.

Why it matters

Low-contrast visual changes can be an early indicator of neurologic shifts, particularly for people living with multiple sclerosis. Repeating short, structured tasks makes it easier to notice trends that everyday vision checks may miss.
