A correctly fitted contact lens rest coultable one thee eye, moves appropriately with each blink, and allows approvate oxygen transmissionon to the rovery. Achieving this requirets consideration of multiple anatomical and physiological factors, including corneal curvature, tear film dynamics, and eyelid anatomy.
