Curable adhesive compositions

Abstract

Curable adhesive compositions are provided that exhibit a high refractive index.

1 - 44 . (canceled) 
     
     
         45 . A device, comprising:
 a) a first ophthalmic component,   b) a second ophthalmic component, and   c) a curable adhesive composition disposed between the first and second ophthalmic components, wherein the adhesive composition comprises
 at least one high index-high viscosity component having a refractive index, before curing, of at least 1.56 at 25° C., and a viscosity, before curing, of at least 15,000cP at 25° C., and 
 a photoinitiator, 
 wherein the refractive index of the adhesive composition, after curing, is:
 i) about equal to the refractive index of at least one of the first ophthalmic component and the second ophthalmic component, 
 ii) between the refractive index of the first lens and the refractive index of the second lens, or 
 iii) about equal to the average refractive index of the first ophthalmic component and the second ophthalmic component. 
 
   
     
     
         46 . The device of  claim 45 , wherein the refractive index of the adhesive composition, after curing, is within 0.03 of the refractive index of at least one of the first ophthalmic component and the second ophthalmic component. 
     
     
         47 . The device of  claim 45 , wherein at least one of the first ophthalmic component and the second ophthalmic component has a refractive index of about 1.67.
