CA 2151325

A method of positioning an ophthalmic lens in a holder forming a concave recess, including the steps of conducting a fluid solution containing a surfactant into the recess, placing the ophthalmic lens in the recess, and positioning the holder so that gravity forces the lens into a predetermined position in the recess. The carrier and the lens may then be transported to a lens inspection position, where the lens may be inspected to determine if it is acceptable for consumer use. The surfactant reduces the friction and the hydrophobic attraction between the lens and the surface of the holder forming the recess, helping to insure that the lens is pulled into the desired, predetermined position in the recess.
