Final answer:
The steps in measuring monocular PDs using the sample frame involve drawing two lines on a sheet of paper, moving away from the sheet to determine the distance at which the lines can be resolved, calculating the diameter of the pupil using a formula, and comparing it to the average pupil diameter.
Step-by-step explanation:
- Draw two lines several mm apart on a white sheet of paper.
- Move away from the sheet as it is held upright, and measure the distance at which you can just distinguish (resolve) the lines as separate.
- Use the formula d = 1.22 * λ / D, where d is the distance between the lines, λ is the average wavelength for visible light, and D is the diameter of your pupil.
- Compare your answer to the average pupil diameter of 3 mm.
