A mold assembly for manufacturing ophthalmic lenses which comprises an anti-tilt feature that prevent relative movement of one half of the mold assembly relative to the other half of the mold assembly. The anti-tilt feature ensures that the edges of the ophthalmic lenses are symmetric around their periphery.

Reduced-tilt back plastic feature for a contact lens mold

The present invention provides molds useful in contact lens production, which molds incorporate a centering and spacing feature in the form of tabs on one of the mold halves. The spacing feature both centers the mold halves in relationship to each other and permits free flow of excess monomer from the mold. Additionally, the spacing feature aids in height control of the one mold half in relation to the other mold half.
