Bifocal contact lenses are for people suffering from presbyopia or astigmatism. Each bifocal lens must be customized to each patientâs needs. A doctorâs method of fitting can either be monovision or multifocal, and they can choose from silicone hydrogel, soft, or GP lens materials. Use a toric single vision soft contact lens on the dominant eye, and a multifocal on the non-dominant eye. 2  If only the non-dominant eye exhibits blurriness, try using a multifocal soft lens in both eyes, or try a toric, single-vision lens in the non-dominant eye.
