Vision Acuity Testing Chart Set

Vision Acuity Testing Chart Sets are a type of ophthalmic instrument used to assess a person's visual acuity. These sets typically include a series of charts or cards with different letters, numbers, or symbols of varying sizes. The charts are designed to be displayed at a specific distance from the patient, usually 20 feet or 6 meters.

During a vision acuity test, the patient is asked to read the characters on the chart from a designated distance. The smallest line or character that the patient can accurately read determines their visual acuity. This measurement is typically expressed as a fraction, such as 20/20, where the numerator represents the testing distance and the denominator represents the distance at which a person with normal vision can read the same line.

Vision Acuity Testing Chart Sets are commonly used by optometrists, ophthalmologists, and other eye care professionals to assess and monitor a patient's visual acuity. They are an essential tool in diagnosing and managing various eye conditions, such as nearsightedness, farsightedness, and astigmatism.

These chart sets can be found in the supply class Ophthalmic Instruments, Equipment, And Supplies, which is part of the larger supply group Medical, Dental, And Veterinary Equipment And Supplies. They are available in various formats, including wall-mounted charts, handheld charts, and digital charts displayed on computer screens.
