Tylec optical occluders for correcting double vision

摘要

There is provided an apparatus for treating individuals suffering from binocular diplopia. The apparatus comprises a frame, having first and second viewing lenses, and includes a mechanism for supporting the frame in an operative position relative to the individual such that the first and second lenses are in front of the left and the right eyes respectively. Each eye of the individual is considered as having a range of vision defined by left and right fields of view. A first occluding device is associated with the first viewing lens, for occluding at least a portion of the right field of view of the left eye. A second occluding device is associated with the second viewing lens, for occluding at least a portion of the left field of view of the right eye. In this arrangement, monocular vision is substantially achieved alternately between the left and right eyes as the eyes scan to the left and right respectively. Methods for treating an individual suffering from monocular and binocular diplopia are also contemplated by the present invention. One such method includes (1) supporting first and second lenses in an operative position relative to the individual such that the first and second lenses are located in front of the first and second eyes of the individual respectively; and (2) occluding an intended line of sight of the first eye by affixing an occluder onto the first lens. Monocular vision is achieved over a complementary line of sight of the second eye.
