Answer :
using the Snellen chart, a vision evaluation of 20/50 mean that the patient can read at 50 feet what most people can read at 20 feet. (Option C)
In vision evaluation using the Snellen chart, the numbers represent the patient's visual acuity. The first number represents the testing distance, which is typically 20 feet. The second number represents the distance at which a person with normal vision can read the same line on the chart. In the case of 20/50, it means that the patient can read at 50 feet what most people can read at 20 feet.
This indicates that the patient has difficulty seeing far objects clearly. They would need to be closer to the object in order to see it with similar acuity as someone with normal vision. A vision of 20/50 suggests reduced visual acuity and may indicate the need for corrective measures such as glasses or contact lenses. It is important for individuals with this level of visual impairment to seek appropriate vision correction and regular eye examinations to ensure optimal visual health.
