Neurochromatic prescription determination

Abstract

A method for determining a lens prescription for the eye. The method includes selecting a first ultraviolet (UV) trial lens and determining whether the first UV trial lens results in improvement in visual function. The first UV trial lens may be selected for the lens prescription when the first UV trial lens results in improvement in visual function. The method includes selecting a first color group comprising a first color trial lens and a second color trial lens and determining whether the first color trial lens or the second color trial lens results in greater improvement in visual function. The second color trial lens may be selected for the prescription when the second color trial lens results in greater improvement in visual function as compared to the first color trial lens. The method may include reevaluating the first UV trial lens for improvement in visual function when not previously selected.

 selecting said second neutral density trial lens for said lens prescription when said second neutral density trial lens results in greater improvement in visual function as compared to said first neutral density trial lens. 
 
     
     
         7 . The method of  claim 1  wherein said first color group is selected from the group consisting of brown, orange, amber, yellow, green, moss green, pink, red, burgundy, rosewood, lavender, violet, royal blue, blue, sky blue, and aqua. 
     
     
         8 . A method for determining a lens prescription, said method comprising:
 selecting a first ultraviolet (UV) trial lens and a second UV trial lens;   determining whether said first UV trial lens or said second UV trial lens results in greater improvement in visual function;   selecting said second UV trial lens for said lens prescription when said second UV trial lens results in greater improvement in visual function as compared to said first UV trial lens;   selecting a neutral density group comprising a first neutral density trial lens and a second neutral density trial lens;   determining whether said first neutral density trial lens or said second neutral density trial lens results in greater improvement in visual function; and   selecting said second neutral density trial lens for said prescription when said second neutral density trial lens results in greater improvement in visual function as compared to said first neutral density trial lens.   
     
     
         9 . The method of  claim 8  further comprising:
 activating a full spectrum lighting element. 
 
     
     
         10 . The method of  claim 8  further comprising:
 activating a camera operable to record said improvement in visual function. 
 
     
     
         11 . The method of  claim 10  wherein said camera is operable to record a pupillary response to said first UV trial lens. 
     
     
         12 . The method of  claim 8  further comprising:
 selecting a first color group comprising a first color trial lens and a second color trial lens; 
 determining whether said first color trial lens or said second color trial lens results in greater improvement in visual function; and 
 selecting said second color trial lens for said prescription when said second color trial lens results in greater improvement in visual function as compared to said first color trial lens. 
 
     
     
         13 . The method of  claim 12  wherein said color group comprises a third color trial lens and said method further comprises:
 determining whether said second color trial lens or said third color trial lens results in greater improvement in visual function; and 
 selecting said third color trial lens for said lens prescription when said third color trial lens results in greater improvement in visual function as compared to said second color trial lens. 
 
     
     
         14 . The method of  claim 13  further comprising:
 reevaluating said first UV trial lens for improvement in visual function after determining improvement in visual function with said second color trial lens when said first UV trial lens did not result in improvement in visual function prior to selection of said second color trial lens. 
 
     
     
         15 . The method of  claim 8  further comprising:
 selecting a first infrared (IR) trial lens and a second IR trial lens; 
 determining whether said first IR trial lens or said second IR trial lens results in greater improvement in visual function; and 
 selecting said second IR trial lens for said lens prescription when said second IR trial lens results in greater improvement in visual function as compared to said first IR trial lens.
