Snellen Chart Test
A visual acuity examination is a fundamental assessment in ophthalmology performed to determine the sharpness or clarity of one's vision. This test commonly involves reading letters on a chart of varying sizes. The standard visual acuity chart, known as the Snellen chart, presents progressively smaller letters that patients to recognize. The results of this examination are expressed as a fraction, such as|e.g., 20/20, where the top number indicates the distance from which the patient can read the letters and the bottom number shows the distance at which a person with normal vision could read the same letters.
