ABSTRACT:
A portable electronic device includes a main body, a camera positioned in the main body, a fill-in light emitting unit positioned in the main body adjacent to the camera, and an optical lens positioned between the fill-in light emitting unit and outside of the main body. The optical lens includes an incident surface facing the fill-in light emitting unit, a light emitting surface opposite to the incident surface, and a plurality of elongated V-shaped ridges formed on the incident surface. The elongated V-shaped ridges are substantially parallel to each other and symmetrical about a central portion of the optical lens. Vertex angles between symmetric elongated V-shaped ridges progressively increase along a direction away from the fill-in light emitting unit.
