Proclear® Multifocal XR monthly contact lenses are designed specifically for people with presbyopia and a prescription outside of the common range. They focus light from both near and far distances to the back of the eye, creating the clearest possible image at any focal length. Proclear® Multifocal XR contact lenses gains their incredible comfort from patented PC Technology, which creates a unique material containing molecules of phosphorylcholine (PC), a substance found naturally in human cell membranes. These molecules attract and surround themselves with water, keeping these lenses moist and comfortable all day long.
