The method comprises advancingly moving substrates, such as ophthalmic lenses, in a batch on a carrier through process vessels which perform respective functions, and reversingly moving the batch at one or more intervals back to at least one of the vessels to perform at least one of the functions again. The coating may be anti-scratch. The ophthalmic lenses may be organic. The functions may comprise ultrasonic cleaning, or primary or de-ionized water rinsing. Also claimed is an apparatus for applying a coating to substrates comprising a driving device for moving a carrier carrying a batch of substrates, process vessels for performing respective functions, and a control system which drives the carrier advancingly through the vessels, and at one or more intervals drives the carrier reversingly to at least one of the vessels. |
