The Invisible Man is a science fiction novella by H.G. Wells published in 1897. Wells' novel was originally serialised in Pearson's Magazine in 1898, and published as a novel the same year. The Invisible Man of the title is Griffin, a scientist who theorises that if a person's refractive index is changed to exactly that of air and his body does not absorb or reflect light, then he will be invisible. He successfully carries out this procedure on himself, but cannot become visible again, becoming mentally unstable as a result.
Russian writer Yakov I. Perelman pointed out in Physics Can Be Fun (1913) that from a scientific point of view, a man made invisible by Griffin's method should have been blind, since a human eye works by absorbing incoming light, not letting it through completely. However, Wells briefly addresses this in Chapter 20. In the passage describing the experiment on the invisible cat Wells wrote "there remained two little ghosts of her eyes" meaning that its eyes (and retinas presumably) were just visible, and thus able to function by absorbing light.
