left eye. Using this information, answer the following
questions:
a. How far was the patient from the eye chart?
b. At what distance would a person with normal acuity be able to
read this line?
Homework Answers
1)A.The eye chart measures visual acuity of a person.
If a person has visual acuity reading of 20/30 then the person is 20 feet away from the chart.It means the patient can only see the letter where normal people can read it at 30 feet.It means the patient has worse than average vision.
B.At 30 feet a normal person with normal acuity can be able to read this.
2)A.If a person has a visual acuity reading of 20/10 then the person is 20 feet away from it.
B.Normal person can see it at 10 feet.

For this problem you will determine the maximum focal length of your eye. A. To determine the maximum focal length of your eye you need to establish how far you can see under ideal conditions (no fog, an...

1. Measure the blind spot by closing your right eye, fixating on the X, and move your head closer or further until you can get the circle to disappear. Then do some geometry to find the visual angle of the blind spot. Measure the distance from the X to the center of the circle. Then measure the distance of the X from your left eye when the circle has disappeared. Now compute the visual angle as seen in...
