an optical lens integrally formed during formation of the retainer and filling a portion of the retainer, the optical lens having an object-side surface facing toward the object-side opening, an image-side surface facing toward the image-side opening, and a lateral surface extending from the object-side surface to the image-side surface,

wherein the retainer and the optical lens are aligned along an optical axis, and

wherein the flange comprises a first oblique surface facing away from the optical lens,

wherein a distance of a tip portion of the flange to the optical axis is smaller than a distance of the lateral surface of the optical lens to the optical axis in a direction perpendicular to the optical axis.

2. The optical lens assembly of claim 1 , wherein the flange further comprises a planar surface and a second oblique surface inclined at an angle less than 90 degrees with respect to the planar surface.

3. The optical lens assembly of claim 2 , wherein the flange surrounds a peripheral portion of the object-side surface of the optical lens.

4. The optical lens assembly of claim 2 , wherein the flange surrounds a peripheral portion of the image-side surface of the optical lens.

5. The optical lens assembly of claim 2 , wherein the flange has an annular shape having a center aligned with the optical axis.

6. The optical lens assembly of claim 2 , wherein the second oblique surface is disposed opposite the first oblique surface and faces toward the optical lens.

7. The optical lens assembly of claim 6 , wherein the first oblique surface and the second oblique surface are arranged relative to each other at an acute angle.

8. The optical lens assembly of claim 1 , wherein the retainer and the flange are integrally made of a same injection molded non-transparent plastic.

9. The optical lens assembly of claim 8 , wherein the non-transparent plastic comprises a black material.

10. The optical lens assembly of claim 1 , wherein the retainer comprises an injection molded non-transparent plastic.

11. The optical lens assembly of claim 1 , wherein the inner surface of the retainer is substantially equal to the lateral surface of the optical lens.

12. The optical lens assembly of claim 1 , wherein the inner surface of the retainer is smaller than the lateral surface of the optical lens.

13. The optical lens assembly of claim 1 , wherein the inner surface of the retainer is greater than the lateral surface of the optical lens.

14. The optical lens assembly of claim 1 , wherein the object-side opening and the image-side opening have a same diameter.

15. The optical lens assembly of claim 1 , further comprising:

a lens barrel configured to receive the optical lens and the retainer along an optical axis.

16. An optical lens assembly comprising:

a retainer having a flange, a hollow space and an outer surface;

an optical lens integrally formed with formation of the retainer and filled a portion of the hollow space, the optical lens having an object-side surface facing toward the object-side opening, an image-side surface facing toward the image-side opening, and a lateral surface extending from the object-side surface to the image-side surface; and

a lens barrel configured to receive the retainer, wherein the optical lens is free from physical contact with the lens barrel,

wherein the flange comprises a first oblique surface facing away from the optical lens, and

wherein a distance of a tip portion of the flange to the optical axis is smaller than a distance of the lateral surface of the optical lens to the optical axis in a direction perpendicular to the optical axis.

17. The optical lens assembly of claim 16 , wherein the flange is annular-shaped and concurrently formed with the retainer, the flange further comprising a planar surface and a second oblique surface inclined at an angle less than 90 degrees with respect to the planar surface.
