1. A method for preparing a lens, comprising:
placing one or more lenses between a first substantially planar surface and a second substantially planar surface, the second substantially planar surface being substantially parallel to the first substantially planar surface;
adjusting a distance between the first and second substantially planar surfaces such that the first and second substantially planar surfaces contact opposing sides of the one or more lenses;
verifying a surface area of the first and second substantially planar surfaces contacting the opposing sides of the one or more lenses; and
coating an exposed portion of the surface of the one or more lenses between the first and second substantially parallel plates with an opaque material to form one or more coated lenses.
