I clean my binoculars as little as possible, and as gently as possible.  I 
roughly follow the procedure described here:

Same for my glasses.  No idea if this amount of care is necessary, but it 
doesn't take that long, so why not?  I find that the dilute detergent removes 
grease that would normally get dust stuck in it again, so one needs to clean 
them less often.

I would only do that for waterproof binoculars.  I tried it carefully on a 
cheap non waterproof pair, and the water got in straight away and fogged them 
up completely

Bob also mentioned camera lenses.  Mine aren't waterproof, so I just blow the 
dust off and use a lens pen to clean them.

Regarding the licking procedure, I recall reading a book (maybe "U-boat War 
Patrol: The Hidden Photographic Diary of U-564"?) about a photographer aboard a 
U-boat.  He resorted to licking the lens to keep it clean in rough weather.

I think I need to lift my game...I clean my binoculars by licking the lenses 
and drying with an old hankie!  Works really well cos it gets rid of any grit 
and I have never scratched a lens with this method!
