Patient Helmut Sechser cleans his old glass eye with water before being fitted for a new one at a medical equipment shop in Munich December 11, 2012. Shop owner and ocularist Gerhard Greiner produces individual hand glass-blown human eye prostheses for people who have lost an eye or eyes due to a trauma, illness or accident. Each glass eye takes about one hour to make, with constant reference to the patient for the right colour and for detailed drawing of the veins. A bespoke glass eye prostheses cost from 350 euros (US $457).A typical modern glass eye is a hollow half sphere that fits over the non-working eye, if it is still there. Otherwise it goes over a ball that has been surgically implanted into the eye socket and attached to the eye muscles. Sechser, 72, got his first glass eye in 1960. Picture taken on December 11.
