Visual acuity is typically recorded in which type of notation?

  1. Decimal Notations

  2. LogMAR Notations

  3. Snellen Notations

  4. Fractional Notations

The correct answer is: Snellen Notations

Visual acuity is commonly recorded using Snellen Notation, which is the most widely recognized method in both clinical and educational settings. This system expresses visual acuity as a fraction, where the numerator represents the distance at which a person being tested can correctly identify the letters on the chart, and the denominator represents the distance at which a person with normal vision can identify the same letters. For example, a visual acuity of 20/20 means the individual can see at 20 feet what a person with normal vision can also see at 20 feet. This notation is intuitive and immediately conveys the level of a person's visual ability compared to the standard vision average. It serves as an effective and practical tool for eye examinations, and because of its longstanding use, it is familiar to most practitioners and patients alike.
