Contrast Sensitivity Testing – Measures Visual Function Under Low Contrast
Contrast Sensitivity Testing is a specialized eye examination available at Desai Eye Hospital to assess how well the eyes can distinguish objects against different levels of contrast. Unlike standard vision tests that measure clarity at high contrast, this test helps in detecting vision impairments that affect daily activities like night driving, reading in dim light, or recognizing faces in low contrast environments. It is particularly useful for diagnosing cataracts, glaucoma, retinal diseases, and neurological disorders.
During the procedure, the patient is shown a series of patterns, letters, or images with varying contrast levels. The responses help in determining how well the eyes can perceive subtle differences in shading and texture. Reduced contrast sensitivity can indicate underlying eye conditions that may not be detected with a regular vision test.
The test is non-invasive, painless, and takes only a few minutes. At Desai Eye Hospital, our specialists use Contrast Sensitivity Testing to detect early vision problems and develop customized treatment plans for optimal visual function.
