Final answer:
A result of 20/60 on a Snellen's chart means that the client can read at a distance of 60 feet what a client with normal vision can read at 20 feet.
Step-by-step explanation:
A Snellen's chart is used to test a client's vision. A result of 20/60 means that the smallest letters that the client can see at a 20-foot distance could be seen by a person with normal vision from 60 feet away. This means that the client can read at a distance of 60 feet what a client with normal vision can read at 20 feet.
