Abstract

A means for attachment of a sight corrective lens (19) adjacent the eyepiece (4) of a respirator includes a lens mount (10) and a lens surround (2), the surround (2) having blind recesses (6b,7b) therein into which engage tabs (9,18) on the mount (10), the tabs (9,18) and recesses (6b,7b) being of different dimensions at different positions around the frames so as to assure a unique orientation of the lens mount (10) in relation to the surround (2) when they are engaged. At least one tab (9,18) may have spaced-­ apart protrusions (15) for interfitting with a lug (7a) projecting radially from its associated blind recess (7b).
