Disclosed are a CMOS image sensor capable of improving the focusing capability of light and a method for manufacturing the same. The CMOS image sensor includes a plurality of first micro-lenses formed in the upper part of the planarization layer, each of the first micro-lenses arranged over a corresponding photodiode, and a plurality of second micro-lenses formed on the planarization layer, each of the plurality of second micro-lenses wrapping a corresponding first micro-lens respectively.
