This is a Snellen Eye Chart. It is used to test visual acuity by having the client stand 20 feet away from the full-sized chart and read as far down as they can. The client can be asked to read lines backwards as well to prevent them from memorizing the letter on a line. Note: it is not full-sized and should not be used to assess anything at this size.

action should the nurse take? •Tests the right eye, then tests the left eye, and finally tests both eyes together. • Assesses both eyes together, then assesses the right and left eyes separately. • Asks the client to stand 40 feet (12 metres) from the chart and read the largest line on the chart.. • Asks the client to stand 40 feet (12 metres) from the chart and read the line that can be read 200 feet (60 metres) away by someone with unimpaired vision.

A patient's visual acuity was tested using a Snellen chart. The results indicated that her vision was 20/50. What does this result mean? Following eye surgery, a man was required to wear an eye patch over his right eye. What effect will this patch have on the man's vision? During a test for near-point accommodation, Subject A had an accommodation distance of 15 cm in both eyes, and Subject B had an accommodation distance of 30 cm. Which one is likely the younger person? Explain.
