A) 20/20
B) 20/30
C) 20/40
D) 20/50

Answer 1

The law generally mandates that you must have at least 20/40 vision in at least one eye to pass a vision test, which can be determined using a Snellen chart.

Step-by-step explanation:

The law typically requires that individuals pass a vision test showing that they have at least 20/40 vision in at least one eye with or without corrective lenses. This standard is based on the use of a Snellen chart, which measures visual acuity. If someone has 20/40 vision, it means that what they can see clearly at 20 feet can be seen by a person with normal vision at 40 feet away. Visual field tests and examinations of the optic disk with an ophthalmoscope are other methods that are used to assess visual health beyond acuity.
