Rigid Gas Permeable Bifocal Contact Lenses

Rigid simultaneous gas permeable contact lenses have the ability to facilitate viewing of objects, which are near in all gazes but is up to the patient whether to view the distance or the nearby image as both are focused on the retina. To obtain perfect vision the patient must train his/her eyes to ignore the hazy near image while focusing on the distant view and vice versa. Also, bifocal contact lenses with an aspheric design offer very good distance as well as intermediate acuity and the near vision is rectified in straight ahead gaze. Rigid annular gas permeable designs have distance, intermediate or near powers arranged in a concentric design. In respect of greater add powers they are better than aspheric gas permeable lenses. A large zone at center provides better distance vision but compromises on the quality of near vision. The converse is also true.
