ABSTRACT:
A method and apparatus are provided for spreading monomer mixture in molds for the centrifugal casting of contact lenses, wherein the said molds containing a monomer mixture are rotated around their axis with the frequency 0.5 to 5 revolutions per minute and, at the same time, the axis of molds is periodically tilted between extreme positions, the angle to the vertical direction of which is in the first extreme position 30.degree. to 60.degree. and in the second extreme position 70.degree. to 100.degree. and the frequency of tilting is twice to ten times lower than the frequency of rotation.
