Feb 21, 2024 · Testing for contrast sensitivity and visual acuity is also different. The test measures how well you can distinguish between light and dark. Your doctor will use a chart where the characters gradually fade from black to gray. Visual acuity is measured when you read the eye chart during an exam.
Jun 17, 2020 · Visual acuity (VA) and contrast sensitivity (CS) characterize different aspects of visual function. Whereas VA is a standard test in routine eye exams and clinical trials, CS is often not included.

Contrast sensitivity measures two variables, size and contrast, while acuity measures only size. Contrast sensitivity is very similar to auditory testing, which determines a patient’s ability to detect the lowest level of loudness of various sound frequencies.
Jun 11, 2023 · Contrast sensitivity (CS) is the ability to perceive sharp and clear outlines of very small objects. It is also defined as the ability to identify minute differences in the shadings and patterns. CS helps detect objects without a clear outline and distinguish them from their background contrast.

Dec 31, 2016 · Least amount of contrast required to make a target visible is called C ontrast Threshold. Its reciprocal is called Contrast Sensitivity. TYPES: Spatial CS- is given by stationary striped patterns or letters (Most of the times we measure only spatial CS)
Oct 18, 2021 · The Functional Acuity Contrast Test is designed to identify vision loss from a variety of disorders, many of which are not detected by high or low contrast Snellen Acuity tests.
When performed using standardized methodologies, contrast sensitivity testing is capable of measuring aspects of visual function that may not otherwise typically be measured by visual acuity, color vision or visual field. When testing for toxicity purposes, multiple different levels of contrast should be included. View chapter Explore book.
