Hybrid lenses are also available. Best rgp multifocal contact lenses: Unlike soft multifocal contact lenses (which move with your eyes), segmented gp bifocal contacts can be designed to stay in a certain position while your eye moves behind the lens.
Independent rgp labs optimum comfort. Segmented gp lenses are smaller in diameter than soft contact lenses and rest on a layer of tears above the margin of your lower eyelid. Visioneering technologies inc (vti) naturalvue is also this type of design, although also termed �extended depth of focus� owing to its single high add.
