You assess a 15-year-old's visual acuity and note her vision to be 20/50 in the right eye. She asks you what that means. You respond:

1. You can see at 50 feet with your right eye what most people can see at 20 feet.
2. You can see at 20 feet with your right eye what most people can see at 50 feet.
3. You can see at 50 feet with your left eye what most people can see at 20 feet.
4. You can see at 20 feet with your left eye what most people can see at 50 feet.

Answer :

With 20/50 vision in the right eye, a person can see at 20 feet what someone with normal vision can see at 50 feet, indicating their visual acuity is less than what's considered normal.So, the correct option is 2) You can see at 20 feet with your right eye what most people can see at 50 feet.

If a 15-year-old has a visual acuity noted to be 20/50 in the right eye, it means that she can see clearly at 20 feet, a person with normal vision can see clearly at 50 feet. Visual acuity is tested using a Snellen chart. In this scenario, the correct response to the student's question would be option 2: You can see at 20 feet with your right eye what most people can see at 50 feet.

Testing visual acuity is a standard procedure in optometry that evaluates how well someone can see the details of a letter at a standard distance, which is usually 20 feet in the United States. With 20/50 vision, letters that should be clear at 50 feet can only be seen at 20 feet, indicating a need for corrective lenses or further eye examination.So, the correct option is 2) You can see at 20 feet with your right eye what most people can see at 50 feet.
