1 - 21 . (canceled)  
   
   
       22 . An auxiliary spectacle apparatus, comprising: 
 (a) two auxiliary lenses;    (b) a hole in each lens;    (c) an auxiliary bridge extending between and connecting said auxiliary lenses to each other;    (d) an attachment for attaching said auxiliary bridge to a primary spectacle; and    (e) lens rivets extending from said auxiliary bridge through said holes to secure said lenses to said bridge;    wherein said lens rivets extend rearward from said auxiliary bridge.    
   
   
       23 . An auxiliary spectacle apparatus as claimed in claims  22 , wherein said auxiliary bridge is Polyflex™ plastic or memory plastic.  
   
   
       24 . An auxiliary spectacle apparatus as claimed in  claim 22 , wherein said lens rivets terminate in a bulb.  
   
   
       25 . An auxiliary spectacle apparatus as claimed in  claim 22 , further comprising at least two holes in each lens and at least two lens rivets extending from each side of said auxiliary bridge through said holes to secure said lenses to said bridge.  
   
   
       26 . An auxiliary spectacle bridge as claimed in  claim 22 , wherein said lens rivets terminate in a cap.  
   
   
       27 . An auxiliary spectacle bridge, comprising a bridge having: 
 (a) lateral ends;    (b) an attachment for attaching said auxiliary spectacle to a primary spectacle; and    (c) lens rivets extending horizontally from said lateral ends;    wherein said lens rivets extend rearward from said auxiliary bridge.    
   
   
       28 . An auxiliary spectacle bridge as claimed in  claim 27 , wherein said auxiliary bridge is Polyflex™ or memory plastic.  
   
   
       29 . An auxiliary spectacle bridge as claimed in  claim 27  wherein said lens rivets terminate in a bulb.  
   
   
       30 . An auxiliary spectacle bridge as claimed in  claim 27 , wherein said lens rivets terminate in a cap.  
   
   
       31 . A spectacle bridge and lenses comprising: 
 (a) two lenses;    (b) a bridge having: 
 (i) lateral ends;  
 (ii) lens rivets extending horizontally from said lateral ends;  
   wherein said lens rivets have a distal end of said lens rivet spread against said lenses.    
   
   
       32 . An spectacle bridge as claimed in  claim 31 , wherein said lens rivets extend rearward from said bridge.  
   
   
       33 . An spectacle bridge as claimed in  claim 31 , wherein said bridge is a bridge for auxiliary spectacles.  
   
   
       34 . A spectacle apparatus, comprising: 
 (a) a primary frame adapted for fitting on a wearer's head, said primary frame having a primary bridge medial in said primary frame;    (b) a ridge extending forward from said primary bridge;    (c) two auxiliary lenses;    (d) an auxiliary bridge extending between and connecting said auxiliary lenses to each other;    (e) an upper projection extending rearward from said auxiliary bridge and a lower projection extending rearward from said auxiliary bridge;    wherein said upper projection and said lower projection of said auxiliary bridge are configured such that there is an upper face, a lower face, and lateral faces, collectively configured to form a snug interference with said ridge which is correspondingly configured.    
   
   
       35 . A spectacle apparatus as claimed in  claim 34 , comprising said protrusions on both said projections, said protrusions configured for releasably engaging said primary bridge.  
   
   
       36 . A spectacle apparatus as claimed in  claim 34  wherein said ridge has a ridge face which extends laterally and said auxiliary bridge has an rearward auxiliary bridge face which extends laterally and said faces are configured such that an interference fit between said faces prevents rotation between said primary spectacle and said auxiliary bridge.  
   
   
       37 . A spectacle apparatus as claimed  claim 34 , wherein said protrusion is beveled.  
   
   
       38 . A spectacle apparatus, comprising: 
 (a) a primary frame adapted for fitting on a wearer's head, said primary frame having a primary bridge medial in said primary frame;    (b) a ridge extending forward from said primary bridge;    (c) two auxiliary lenses;    (d) an auxiliary bridge extending between and connecting said auxiliary lenses to each other;    (e) an upper projection extending rearward from said auxiliary bridge and a lower projection extending rearward from said auxiliary bridge and at least one said projection is elastic; and    (f) at least one protrusion on at least one of said projections;    wherein the lateral shape of said projections and the corresponding lateral shape of said ridge prevents horizontal movement of the apparatus when assembled.    
   
   
       39 . A spectacle apparatus as claimed in  claim 38 , comprising said protrusions on both said projections, said protrusions configured for releasably engaging said primary bridge.  
   
   
       40 . A spectacle apparatus as claimed in  claim 38  wherein said ridge has a ridge face which extends laterally and said auxiliary bridge has an rearward auxiliary bridge face which extends laterally and said faces are configured such that an interference fit between said faces prevents rotation between said primary spectacle and said auxiliary bridge.  
   
   
       41 . A spectacle apparatus as claimed in  claim 38 , wherein said protrusion is beveled.
