摘要

A method for determining whether a sealing area of a primary packaging container for an ophthalmic lens is unacceptable for properly sealing a foil to the sealing area is disclosed. The method involves comparing the temperature of an infrared image of the sealing area to a reference temperature to determine if the difference in temperature exceeds a predetermined threshold.
