Yup, and this makes me think that the advice to put brighter light on your reading to make things sharper doesn't work because of greater light availability, but because it provokes the pupil to narrow and increase the pinhole camera effect -- or more to the point, not that the bright light doesn't itself help, but how much is due to more light vs provoking smaller pupil opening? |
