Abstract
An optical lens has a light sensing die integrated into the optical lens. The optical lens is extended compared to a spherical optical lens such that the optical lens is elongated in order to allow for placement of the ambient light sensing die without causing any blocking or distortion of the optical lens. The shape of the optical lens and the placement of the ambient light sensing die is compensated for the change in shape compared to a spherical optical lens thus allowing for correct focal length parametrics.
