ABSTRACT OF THE DISCLOSURE An original solution for producing a soft contact lens by a direct casting method is disclosed. The original solution contains: a component A selected from the group consisting of monomers and post cross-linkable hydrophillic polymers wherein the monomers yield hydrophillic component when polymerized; a component B selected from the group consisting of monomers and postcross-linkable hydrophobicpolymers wherein the monomers yield hydrophobic component when polymerized; and a suitable solvent C. The weight ratio of A:B is from about 85:15 to about 55:45 and the amount of solvent C is about 5 to 95% by weight, at least one of the components A and B is a post cross-linkable polymer. This solution has the advantage of providing a lens which is both optically homogenous and free from bubbles.
