Optical lens and method of making the same

摘要

An optical lens includes a lens member and two shade layers on opposite sides of the lens member. The lens member respectively has a lens portion on each side thereof. Each shade layer has an aperture above the corresponding lens portion of the lens member to serve the function of aperture. A method uses optical lithography technique to make such optical lens in a fast way, and the shade layers will have a strong bonding strength with the lens member.
