I wear glasses for reading & driving, and recently changed my glasses.

The thought occurred that glasses come with a cleaning cloth (silk I think?) could you use this and the glasses cleaning fluid to clean camera lenses.

Has anybody tried it, and what do people think about it.

Colin

I wear glasses that come from Spec Savers. They provide a cleaning cloth with the Pentax logo on it. I have tried this on my Tamron and it seems to be OK. Spec Saver use Pentax lens I think.

Yeah the cloths are certainly okay, don't know about the fluids though but the coatings shouldn't differ so much I think.

Spec Savers use Pentax lenses, although they're not all glass, my reactions are plasti but work OK.

I use computer monitor cleaning spray if I buy a lens which is really grubby, it doesn't seem to harm the coatings. I've also used glasses cleaning spray although that stuff is a bit expensive.

The main thing is to make sure that the cloth you use isn't abrasive and has no dust or grit on it. I tend to use a fresh cotton bud for wet cleaning of lenses then follow up with the lens pen to polish off any watermarks left by the fluid.

I doubt I'd use the same cloth for glasses and lenses though - have you seen the state your glasses get into after wearing them while cooking with a frying pan?

No. I can't see a thing after frying!

These days, I try to avoid cleaning lenses unless absolutely necessary. When I have to, a product I have found to work well with filters and lenses is 'Calocoat' which can be used with 'Calocloth' or any other high quality microfibre cloth. I always spray a little onto the cloth and not directly onto the filter/lens when cleaning and always use a 'blower' to remove dust/particulates first. Unlike so many other cleaning products I have had the misfortune to buy/try, this combination does not leave residual 'smears'; even on Hoya Pro-1 filters, which in my experience are a real bugger to clean.

Both the cleaner and cloth are remarkably inexpensive and can be obtained from 7dayshop.com

Regards,

Jon

The Pentax lens cloth is the best I've ever used to clean my spectacles. I went to get a couple every time I went to Britain. Now SpecSavers have opened shops in Norway, so maybe I can get the cloth locally hereafter.
Best regards
