The normal human eye has maximum visual acuity with a pupil size of about 3. For larger pupils, acuity decreases due to increasing aberrations; for smaller pupils, acuity decreases due to increasing effects of diffraction. If your pupil diameter is 2 , as it would be in fairly bright light, what is the smallest diameter circle that you can barely see as a circle, rather than just a dot, if the circle is at your near point, 25 from your eye? Assume the light's wavelength in air is 600 and the index of refraction inside the eye is 1.33.
