The depth of the center is greater than that of the periphery. The two side edges are arc-shaped, and the upper and lower edges are flat. A recess 1 4 with a greater height than the upper and lower edges is arranged in the middle of the upper edge and the middle of the lower edge of the upper mold lens cavity 1 3. The top end of the recess 1 4 of the upper edge is connected with the upper mold runner 7. A lower mold lens cavity 1 6 is arranged on the surface of the lens lower mold 1 1, which is a convex spherical surface. The height of the center is greater than that of the periphery. The two side edges are arc-shaped, and the upper and lower edges are flat. A recess 1 7 with a greater height than the upper and lower edges is arranged in the middle of the upper edge and the middle of the lower edge of the lower mold lens cavity 1 6. The top end of the recess 1 7 of the upper edge is connected with the lower mold runner 1 2. Through the above arrangement, the formed eyeglass lens forms a convex upward and downward in the middle of the upper and lower edges. Thus, the mold line 33 formed in the injection molding process can be located in the convex, avoiding the mold line 33 being located in the effective cutting range of the eyeglass lens, which is beneficial to the cutting of the lens, improves the utilization rate of the lens, reduces the waste in the cutting process of the lens, and is beneficial to saving production cost.
