The Snellen chart is used to measure visual acuity, which is the clarity or sharpness of vision. It consists of a series of letters or symbols arranged in rows that decrease in size, allowing individuals to read from a specified distance. The results help determine the need for corrective lenses or assess eye health. It is commonly used in eye examinations by optometrists and ophthalmologists.
