An apparatus for fabricating a lens includes an injection port to inject a source material, a molding frame filled with the source material and including a plurality of forming molds adjacent to each other, and a light source or a heat source to cure the source material filled in the forming molds. The forming molds include at least four connection passages connected to the forming molds. A method for fabricating a lens includes injecting a source material through an injection port of a molding frame which includes a plurality of forming molds adjacent to each other and at least four connection passages connected to the forming molds, filling the source material in the forming molds and discharging the source material out of the forming molds through the connection passages, applying a pressure to the source material, and curing the source material.
