Abstract: In a method of handling an ophthalmic lens contained in an inspection cuvette and immersed in an inspection liquid the lens is arranged at an actual position relative to a concave inner surface of a bottom glass of the inspection cuvette;
The method comprises the steps of: positioning the inspection cuvette in a handling position without pivoting the inspection cuvette; through the viewing glass obtaining an image of the lens; from the obtained image determining a deviation of the actual position of the lens from a set transfer position; comparing the deviation with a predetermined maximum deviation; determining that the lens is arranged at a proper transfer position when the deviation is less than the maximum deviation, in case of the proper transfer position, transferring the lens from the inspection cuvette to the primary packaging container.
