Abstract

Apparatus for colouring the peripheral regions of spectacle lenses comprises a basket with longitudinal shafts rotatable at adjustable speeds located near the bottom of the basket. Pairs of adjacent shafts are spaced apart less than the diameter of the lenses which are supported vertically in annular grooves in the shafts. The basket is raised and lowered vertically relative to a dye bath so that the rotating lenses are immersed to a predetermined depth in a heated and stirred dye bath to dye the peripheral edges. In the production of two colour lenses for spectacles or sunglasses. High output of coloured lenses with controlled colour variation from the periphery to the centre.
