Point Spread Functions in Ophthalmology
PSFs have recently become a useful diagnostic tool in clinical ophthalmology. Patients are measured with a wavefront sensor, and special software calculates the PSF for that patient’s eye. In this manner a physician can "see" what the patient sees. This method also allows a physician to simulate potential treatments on a patient, and see how those treatments would alter the patient’s PSF. Additionally, once measured the PSF can be minimized using an adaptive optics system. This, in conjunction with a CCD, can be used to visualize anatomical structures not otherwise visible in vivo, such as cone photoreceptors.

“I philosophize from the vantage point only of our own
provincial conceptual scheme and scientific epoch, true; but I know no better.”
—Willard Van Orman Quine (b. 1908)
“Cows sometimes wear an expression resembling wonderment arrested on its way to becoming a question. In the eye of superior intelligence, on the other hand, lies the nil admirari spread out like the monotony of a cloudless sky.”
—Friedrich Nietzsche (1844–1900)
“Nobody is so constituted as to be able to live everywhere and anywhere; and he who has great duties to perform, which lay claim to all his strength, has, in this respect, a very limited choice. The influence of climate upon the bodily functions ... extends so far, that a blunder in the choice of locality and climate is able not only to alienate a man from his actual duty, but also to withhold it from him altogether, so that he never even comes face to face with it.”
—Friedrich Nietzsche (1844–1900)
