Answer :
Final answer:
A Snellen chart result of 20/50 indicates that the patient has worse-than-average visual acuity, meaning they can see at 20 feet what a person with normal vision can see at 50 feet.
Explanation:
A result of 20/50 on a Snellen chart test means that what a person with normal vision can see at 50 feet, the tested patient can only see clearly at 20 feet. This result indicates that the patient has lower visual acuity than the average person. The Snellen chart is typically used in an optometry office to determine visual acuity by having the patient read letters of decreasing size from a standard distance of 20 feet.
Such vision testing is crucial for diagnosing and managing vision problems. If necessary, additional testing can be performed to assess peripheral vision and inspect the optic disk through an ophthalmoscope for further understanding of the visual health of the patient.
