An apparatus for carrying an ophthalmic lens, particularly while the lens is being inspected, including a base member and a well connected to the base member. The well is substantially transparent, and includes a frusto-conical sidewall having a constant slope, and a hemi-spherically shaped bottom portion connected to an extending downward from the sidewall. The bottom portion of the well has curvature that is about 10% larger than the radius of curvature of the ophthalmic lens.
