Electronic visual acuity (VA) charts are used to determine a person's visual sharpness by presenting standardized optotypes (letters, numbers, or symbols) of varying sizes on a screen. These charts offer the advantages of eliminating memorization, randomizing optotype presentation, customizing parameters like contrast and display time, and allowing remote control and even self-assessment through mobile apps. They are standard tools in eye examinations for eye prescription (refraction), diagnosing vision problems, and monitoring eye health.
