Abstract: This invention pertains to an attachment for bifocal eyeglasses which is a dynamic frame fitted with the lens for intermediate vision which will lie in front of the middle one third of the bifocal lens during computer use providing three zones of vision at a time without changing the head position or changing to a separate computer eye glass. This attachment along with the bifocal eye glass enables the optical centers of the distant vision and intermediate vision lens to overlap with each other falling on the visual axis, coinciding with the pupillary center of the eye at the primary head position overcoming strain, distortions and aberrations. This dynamic frame is locked at the side of the main frame with the help of press locks when ‘not in use’. This invention makes long hours of computer work comfortable and helps to overcome computer vision syndrome.

Abstract: The dynamic multifocal spectacle frame is an improvement on the regular spectacle frame which is meant to enable the spectacle user to see the objects clearly which lie at the intermediate vision zone (i.e. 50 cm to 100 cm) e.g. computer monitor. This frame is incorporated with a mobile second set of frames fitted with the third power lens. This second set of frames are attached to the hinges provided on the lateral aspects of the spectacle frames, just below then hinge of the first frame. From here it is freely rotatable by 270° to the front i.e., in front of the first spectacle and back to the arms of the first spectacle. There are press locks provided near the nose pad and at the arms of the first frame to hold the second set of frames in position, while in use and while not in use respectively. This can be used for bifocal purposes also.
