What is measured by the contrast sensitivity testing?

The retina's ability to detect colors
The ability to see at various distances
The retina's ability to detect differences in luminance
The clarity of visual images

The correct answer is: The retina's ability to detect differences in luminance

Contrast sensitivity testing measures the retina's ability to detect differences in luminance, which is essential for visual function, particularly under low light conditions or with low-contrast images. This type of testing evaluates how well a person can see and discern contrast in various light conditions, which is crucial for daily activities such as driving at night or distinguishing objects in foggy weather. Unlike color vision tests, which assess the ability to perceive colors, contrast sensitivity testing focuses specifically on how effectively the visual system can identify variations in brightness. This ability can be impaired in various conditions, including cataracts and retinal diseases, making it a vital aspect of a comprehensive ophthalmic assessment.
