What is the visual acuity of the better eye if one eye is 20/50 and the other eye is 20/70 (with glasses)?

1) 20/50
2) 20/70
3) 20/20
4) Cannot be determined

Answer :

Final answer:

The visual acuity of the better eye can be determined by comparing the measurements of both eyes: one eye is 20/50 and the other eye is 20/70. The correct answer is option 2) 20/70.

Explanation:

The visual acuity of the better eye can be determined by comparing the measurements of both eyes: one eye is 20/50 and the other eye is 20/70. The visual acuity measurement is a comparison of how well a person can see compared to a person with normal vision.

In this case, 20/50 means that the person can see at 20 feet what a person with normal vision can see at 50 feet. 20/70 means that the person can see at 20 feet what a person with normal vision can see at 70 feet.

Since the visual acuity of the better eye is a measure of how well the person can see compared to a person with normal vision, the visual acuity of the better eye would be 20/50.
