When you ask your patient about his vision, he says that the last time he had it tested, it was recorded as 20/50. This means that:
1. the patient can read at 20 feet what a person with normal vision can read at 50 feet.
2. the patient can read at 50 feet what a person with normal vision can read at 20 feet.
3. the patient needs to be 50 feet from objects to see them.
4. the patient's best vision is between 20 feet and 50 feet from objects.
