Abstract
A molding apparatus for generating toric contact lenses, comprises a convex inserter, a front convex inserter carrier, a rear convex inserter carrier, and a first and a second fasteners. The convex inserter, used to form a convex outer surface of toric contact lens, has positioning lines on its convex head. It is embedded in the front convex inserter carrier which also has positioning lines on its upper brim, jointing with the convex inserter, and an angle pointing line on its cylindrical surface. A first fastener is used to helically tighten the convex inserter to the front convex inserter carrier while a second fastener joining the front convex inserter carrier with the rear convex inserter carrier. The front convex inserter carrier is embedded in the rear convex inserter carrier which has a number of lines representing angles of astigmatism on its cylindrical surface.
