In connection with the heretofore commonly molded soft corneal contact lens, a substitute manufacturing method is used so as to embody the lens with air vent configurations which effectively resist flattening during use, the referred to substitute method including forming impressions in the lens construction material in the locations of the air vents which increases the density in the walls bounding the air vents so that these walls do not collapse, or flatten, during use.
