Abstract
A double lens includes a front lens member, a back lens member and a gasket. A back curve side of the front lens member and a front curve side of the back lens member are contraposed in parallel, and fixed together with the gasket, at least one of the back curve side of the front lens member and the front curve side of the back lens member has an antifogging film which is formed avoiding part of a gasket bonding area. This double lens provides goggles or a shield in which fogging is less likely to be generated, the gasket is less likely to be separated, and the front curve side of the front lens member is less likely to be damaged.
