Abstract

The present invention relates to contact lenses which reduce indoor glare and provide improved comfort to the wearer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A contact lens comprising at least one photochromic dye in an indoor glare reducing effective amount, said contact lens having, at about body temperature, a percent transmission between 70 to 90% across the region of 420-700 nm. 
     
     
         2 . A contact lens comprising a central circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, wherein said central circular area has, at body temperature, a percent transmission between 70 to 90% across the region of 450-660 nm, wherein said central circular area comprises at least one photochromic dye in an indoor glare reducing effective amount, said contact lens. 
     
     
         3 . The contact lens of  claim 2  wherein said peripheral zone has a percent transmission in the UV range of less than about 20%. 
     
     
         4 . The contact lens of  claim 2  wherein said peripheral zone is capable of substantially blocking the transmittance of UV, blue light or both. 
     
     
         5 . The contact lens of  claim 2  wherein said peripheral zone is capable of blocking at least about 90% of the transmittance of UV light. 
     
     
         6 . The contact lens of  claim 2  wherein said central circular area has a diameter of between about 4 and about 9 mm. 
     
     
         7 . The contact lens of  claim 2  wherein said central circular area has a diameter of between about 6 and about 9 mm. 
     
     
         8 . (canceled) 
     
     
         9 . (canceled) 
     
     
         10 . The contact lens of  claim 2  wherein said central circular area comprises dots comprising at least one dye in an indoor glare reducing effective amount. 
     
     
         11 . The contact lens of  claim 1  wherein said percent transmission is between about 75 to about 90% across the region of 420 to 700 nm. 
     
     
         12 . The contact lens of  claim 1  wherein said percent transmission is between about 80 and about 90% across the region of 420 to 700 nm. 
     
     
         13 . The contact lens of  claim 1  wherein said percent transmission is between about 75 to about 90% across the region of 450-660 nm. 
     
     
         14 . The contact lens of  claim 1  wherein said percent transmission is between about 80 and about 90% across the region of 450-660 nm. 
     
     
         15 . A method for reducing indoor glare discomfort in contact lens wearers comprising applying to each eye of said contact lens wearer a contact lens comprising at least one photochromic dye in an indoor glare reducing effective amount, said contact lens having percent transmission at about body temperature between 70 to 90% across the region of 450-700 nm. 
     
     
         16 . A method for reducing glare discomfort in contact lens wearers comprising applying to each eye of said contact lens wearer a contact lens comprising a central circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, wherein said central circular area has, at body temperature, a percent transmission between about 70 to about 90% across the region of 420-700 nm, wherein said central circular area comprises at least one photochromic dye in an indoor glare reducing effective amount, said contact lens. 
     
     
         17 . The contact lens of  claim 1  further comprising a circular area centered at a geometric center of the lens and having a diameter of about 1 to about 9 mm and a peripheral zone, and wherein said peripheral zone comprises a color print, iris pattern or a combination thereof. 
     
     
         18 . (canceled) 
     
     
         19 . The contact lens of  claim 9  wherein said dye comprises at least one photochromic dye and at least one conventional colorant. 
     
     
         20 . (canceled) 
     
     
         21 . (canceled)
