Answer:
While eye testing, systems of lens are used to find out the power of the eye. However, a plane mirror is used to make the alphabets seem at a further distance from the patient.
In case of mirror angle of incidence (i) is equal to the angle of reflection (r).
Linear magnification means the apparent increase in size of the image after refraction by a lens.
In case of a lens angle of incidence and angle of refraction can never be equal.
