According to the present invention, there is provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens and a connecting portion connecting the flash ring to the contact lens, wherein the thickness of the connecting portion is less than the thickness of the outer edge of the contact lens. There is also provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens, and a connecting portion connecting the flash ring to the contact lens wherein the mass of the flash ring is at least forty times greater than the mass of the contact lens, suitably at least sixty times greater than the mass of the contact lens. There is also provided a contact lens injection molding apparatus comprising first and second molding parts moveable relative to each other between a compressed and an uncompressed position, wherein in the compressed position, an outer edge of the first molding part is disposed 1 to 50 nm from an outer edge of the second molding part.
