Abstract of the Disclosure
Eyewear for enhancing the contrast sensitivity of the human vision system through the use of lenses subdivided in areas of different light filtration properties arranged in specialized patterns, called multi-filters patterns, are provided. Of the multiple filtration areas, or filters, that compose each multi-filters patterns, one or more filters heavily reduces or totally block light arriving from some areas of the visual field of the eyes , while other filters lightly reduce or totally allow light from other areas of the same visual field. The resulting effect is to drive the auto-exposure function of the eye-brain vision system to adapt itself to areas of interest of the visual field thus improving contrast sensitivity and vision acuity in those areas while reducing or blocking light and glare from the rest of the visual field. The “multi-filters pattern” technology of the present invention can be implemented in lenses of stand-alone eyewear or as attachable “clip-on” lenses, to provide vision acuity improvement to stand-alone eyewear.
Summary of the Invention
[0025] According to the invention, optical light filtering elements of different filtration properties are disposed in a tessellated, i.e., mosaic arrangement adjacent to one another to completely cover the field of view of the eye with the result of enhancing visual acuity.
[0026] It is thus one object of the present invention to maximize vision acuity and to minimize vision problems due to insufficient contrast sensitivity in low ambient light or in scattered or backlit light conditions.
[0027] Another object of the present invention is to provide eyewear, in particular, but not limited to, eyeglasses having lenses made of specialized patterns of multiple light filters of different filtration properties, hereto called “multi-filters patterns”.
[0028] Another object of the present invention is to provide eyewear, and particularly eyeglasses, in which each lens is made of specialized patterns of multiple light filters of different filtration properties, with each pattern designed to enhance contrast sensitivity in specific zones of the visual field.
[0029] A further object of the present invention is to provide eyewear having lenses made of multi-filters patterns to enhance vision in tasks like, but not limited to, aiding work at a bench or desktop, or taking an outdoor walk under dappled sunlight conditions, or target shooting, or reading music sheets while playing an instrument, or working at a computer screen in an ambient with disturbing light sources around, or evaluating the quality of products traveling on a conveyer belt on a production floor, and in all tasks where improved contrast sensitivity in a specific part of the visual field increases productivity or safety.
[0030] A further object of the present invention is to provide eyewear having lenses made of multi-filters patterns to aid people with special vision needs due to disabilities or disease or vision decline by old age Such multi-filters patterns, customized for a specific visual need, adjusts the filters contours and properties to the vision acuity performance of the retina, to maximize the contrast sensitivity of the best performing parts of the retina of the user.
[0031] A still further object of the invention is to enhance prescription eyewear with the addition of multi-filters patterns technology.
[0032] Another object of the present invention is to provide eyewear with lenses made of multi-filters patterns in which the borders separating one filter area from the others have smooth transitions of the filtering properties yielding eyewear more esthetically acceptable.
[0033] Another object of the present invention is to provide eyewear with lenses made of multi-filters patterns in which the transitions areas, occupy most or all lens area.
[0034] In a specific embodiment of the invention, eyewear is provided in which contrast sensitivity is enhanced using lenses made of specific patterns of multiple light filters of different filtration properties, hereto called “multi-filters patterns”. An eyewear lens that mounts a multi-filters patterns, in accordance with the present invention, has one or more areas of dark filters that highly reduce or totally block light transmission, and it has one or more other areas with weak or clear filters that reduce little or none light transmission The resulting structure, when worn, forces the auto-exposure function of the eye-brain vision system to adjust itself solely, or mainly, to the areas of high light transmission, resulting in better contrast sensitivity in those areas.
[0035] Another object of the present invention is to provide eyewear, having lenses made of multi-filters patterns, that include a clip-on mechanism to attach said eyewear to standard eyeglasses, so that contrast sensitivity enhancements is added to standard eyewear, when the clip-on with the multi-filter pattern is attached to it.
[0036] These, other objects of the invention, and other intended features, will become more easily visible when reference is made to the following description and the accompanying drawings.
