Peeling, of the central anterior lens capsule in sheetlike lamellae was first described by Elschnig 
in glass blowers in 1922. The tanks of molten glass they worked with reached temperatures of 
up to 1500°C, giving off thermal radiation rich in infrared rays. Capsular peeling  require several 
decades of such exposure. The use of protective goggles has eliminated most of this problem.
