And immediately there fell from his eyes as it had been scales: and he received sight forthwith, and arose, and was baptized. There fell from his eyes as it had been scales - This was real: he had been so dazzled with the brightness of the light that we may suppose the globe of the eye, and particularly the cornea, had suffered considerable injury. The structure of the cornea was doubtless much disturbed, and the whole of that humor would be rendered opaque, and incapable of permitting the rays of light to pass through the different humours to the retina, where all the images of things transmitted through the lenses, or humours, are distinctly painted. In the miraculous cure the membrane was restored to its primitive state, and the opaque matter separated from the cornea, in the form of thin laminae or scales. This being done, the light would have as free a passage as formerly, and the result would be distinct vision.
