Abstract
The invention relates to a method for producing embedded hydrogel contact lenses each having a magnetized insert that comprises magnetic particles and is centrally embedded in the bulk hydrogel material of the embedded hydrogel contact lens. During molding, a magnetized insert can be centered and held in position in a lens mold by using a magnet placed below the lens mold. The invention also relates to an embedded hydrogel contact lens produced from a method of the invention.
