Distance between the eye and eye chart must be 6 meter during examination of visual acuity. Why?
Suppose you measure the scanning (4x) field of vision diameter with a stage micrometer and it is 2 mm. If high power is 40X, and gives 10X more magnification than scanning power, how big will the diameter of the field of vision be using high power?
The pupil of a person's eye changes from a diameter of 3.5 mm to 1.5 mm as the
illumination is increased. By what factor does the minimum angle of resolution
change?

To be able to drive safely and obtain his driving license, he needs to be able to clearly see objects up to 100 m away. In this problem, Pmin eye = minimum optical power of the patient’s natural eyes, Pmin combo = minimum optical power of the patient’s natural eyes + corrective glasses, and Pmin glasses = minimum optical power of the corrective glasses. Questions: What is the cause of the patient’s vision problems (i.e., his medical diagnosis)? What does this diagnosis mean for the patient? If the patient opted to purchase glasses, would corrective lenses create real or virtual images in the patient’s field of vision? Would the eye interpret images produced by the glasses as real or virtual images? What assumptions can be made about the size of the patient’s eyeball and their lens-retina distance (units of m)?
