Abstract
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.
