D) Weber test

Accepted Answer

The Snellen eye chart is used to test visual acuity by measuring the sharpness of a person's vision. It consists of letters or symbols that are arranged in decreasing size. The person being tested is asked to read the letters or symbols from a specific distance, with each eye separately and then both eyes together. The results are recorded as a fraction, with the top number representing the distance of the person from the chart and the bottom number representing the size of the letter or symbol they were able to read.
