  • Publication number: 20040179167
    Abstract: Methods of manufacturing hybrid contact lenses using a mold are provided. The methods include pouring liquefied resin of a substantially rigid material within an inner section, curing the substantially rigid material, pouring liquefied resin of a substantially flexible material within an outer section and curing the substantially flexible material. In some embodiments, a wall disposed between the rigid and flexible materials is angled and/or bent to increase bonding strength between the rigid and flexible sections. The curing steps involve the application of heat, UV light, or a combination of both heat and UV light.
