Cleaning lenses

I've just picked up my new spectacles and also got some liquid Coated Lens Cleaner. The little pump spray says "Cleans all coated and multicoated optical lenses" and "Non-toxic, anti-static formula, contains no alcohol or solvents".

So I thought, hmmmm....!

Up until now I've been using a lens pen (wonderful gadget, highly recommended!) but I wondered if this stuff would:

1) Be safe to use on my Nikkors (fnar!)

2) Give any better results

What do you reckon?

All the best,

Frank

IMO using anthing that can get inside the les itself(liquids,etc.)is always risky and I tend not to use anything more than a lens cloth(without anything on it).If it really needs cleaning you may want to see how much it costs to get professional cleaned rather than ruin a lens.

I'm sorry Frank-I just re-read your question.I thought you meant lenses-as for eyeglasses I'm not sure-you can always check withthe nearest eyeglaases place to make sure it won't harm your script.

Lens Cleaning...

Of all the saddest things of mice or men ... the saddest are these ... the lenses that have been massacred by constant, knee-jerk cleaning.
Occasionally,one comes across them in the "Used" areas, Beautiful Leica and Hasselblad lenses - with a central, translucent spot...

I worked, in a different life, for a company involved in the production of *Highly* sophisticated optics. I saw one on-the-spot firing: against all his training, this guy "cleaned" a lens he thought to be "dirty" with a pencil eraser. This lens was one with a special - I think it was eight- layer coating, which was immediately destroyed.

My best cleaning advice is **DON'T**!!. It takes a LOT of "dirt" to affect lens performance. What will be impacted most is contrast. If at all possible DON'T clean that lens!! Whatever - "Pens", "Miracle Cloths" - Grinding Wheels and Drano - comes in contact with that lens (actually the coating - much softer than the glass itself is most vulnerable), will have an adverse effect - to some degree.
Put "UV" or "Clear" (there's a difference?) filters on the lens, and leave it there wherever possible. Clean the filter if you must - even the most expensive Heliopan is less "dear" than the lens.

We were allowed the use of *one* "system" - distilled water and surgical cotton - with *no* pressure on the cotton. If that did not remove whatever was on the lens - it went to Technicians specifically trained in cleaning - which was most of the time, anyway.

Jim, you read it right the first time; I did mean my camera lenses. Good point, well made.

Ed, All my lenses wear Hoya HMC Skylight 1B's (almost as clear as UV's, but with a little added warmth which I find pleasing) and the only time they ever come off is to gently flick away dust particles (how the *heck* do they get in there?!) with a very soft brush.

You are of course right. Let's put this down to a temporary aberration on my part and move along!

Thanks
