Sanpaku Know How Many Holes It Takes To Fill The Albert Hall", which may be found in "Demon Box" (Methuen, 1986, p. 297). Sanpaku According to Chinese medical face reading, when the white part of the eye, known as the sclera, is visible beneath the iris, it represents physical imbalance in the body and is claimed to be present in alcoholics, drug addicts and people who over-consume sugar or grain. Conversely, when the upper sclera is visible it is said to be an indication of mental imbalance in people such as psychotics, murderers, and anyone rageful. It was held that stress
Aberrations of the eye converge to a perfect point, the wavefront emerging from the optical system must be a perfect sphere centered on the image point. The distance in micrometers between the actual wavefront and the ideal wavefront is the wavefront aberration, which is the standard method of showing the aberrations of the eye. Therefore, aberrations of the eye are the difference between two surfaces: the ideal and the actual wavefront. In normal population the dominant aberrations are the ordinary second-order spherocylindrical focus errors, which are called refractive errors. Higher order aberrations are a relatively small component, comprising about 10% of the eye's total
