Contrast sensitivity
A key element for comfortable vision

What is contrast sensitivity?
Contrast sensitivity refers to the ability of the eye and brain to perceive differences in brightness between light and dark areas. Unlike visual acuity, which measures the ability to read letters, it assesses how you perceive details in varied environments.
Low contrast (harder to see)
Good contrast (sharper vision)
Why is it important to test your contrast sensitivity?
See better in all situations
Good contrast perception makes it easier to see at dusk, in cloudy weather, or in dimly lit environments.
More everyday safety
Contrast is essential for driving, especially at night or in bad weather, when light differences are reduced.
Detect potential problems early
A decrease in contrast sensitivity can be an early sign of certain eye conditions (cataracts, macular degeneration, etc.).
A better quality of life
Good contrast vision helps you fully enjoy your activities: reading, sports, hobbies, screen work, etc.
