Answer is given below
Step-by-step explanation:
we consider here gap in character size is 0.75 mm
and distance is 300 mm
so minutes of arc is = 0.85944
and
visual acuity is express as
V = standard view distance D รท distance at which each letter D' ................1
- There is visual acuity under the eyes, on which the object cannot be determined
- Factor factor mainly determines refractive error and contrast angle brightness or brightness and duration of contrast and exposure
- The target resolution threshold is expressed as a small angle, which can reduce the distinction between important elements of the stimulus pattern such as a pair of dots.
- Relaxation is specified in terms of its angular size
