Superglue On Lenses

[Bazile]

Accidentally got superglue on spectacle lens .

Wipe it off , however it left a semi- transparent patch .

Is there any product that can get rid of the patch , or is it now engrained into the lens material ?

[bookbinder]

My bottle of Loctite super glue gives advice only if the stuff gets on skin. But it might be worth a try: use soap, hot water, and a blunt edge, e.g. teaspoon handle. Can't do any harm.

Depends a lot on the lens material. Plastic or glass?

[Bazile]

Plastic

The patch is smooth , when you run your finger over it

[woofgang]

are the glasses now ruined or can you still use them? You might contact the place you got the glasses from to get advice. If they are ruined anyway I would try the Loctite glue remover on the basis that things can't get worse

I have used surgical spirit to remove superglue from glass lenses, not sure if it would affect plastic but.

I have used nail-polish remover to get rid of super-glue.

Fender62, I think it would depend upon the type of plastic you're using it on since the remover itself comes in a plastic container.

Nail varnish remover is most likely a solvent for the lens plastic so only use it as a last resort. y
You can test the NVR by putting a very small spot on a part of the lens that you don't usually look through, leave it to dry and then see if you can wipe every trace of it of with a soft cloth. If it leaves a mark of any kind don't use it.

IMO it is worth a try as it seems a ruined lens otherwise, to me.

Of course if your lens were coated it may just be the coating damaged, and replaceable.

Nail-polish remover (which is mainly acetone) has quite a few uses other than the one it is marketed for, but it's not nearly as versatile as 10W30.

Model shops sell a product made by Pacer Industries called Zap Z-7 Debonder.
It's American but is available in the UK and even on EBay.
See item no. 121373444704. The rear label says it 'will not craze most plastics', but I would test it first. I have used it and it does soften the superglue enough to get rid of it more easily using a cotton bud. I've followed up on plastic with judicious application of metal polish. T-Cut would be too harsh. Good luck.

That sounds like a good product to have around the house, rccatnap, and they have a very informative web-site.

I'd contact your optician for advice.

[stuey]

Boxtops, I like your use of the word "I'd" in reference to an optician:)

NEVER use acetone on plastic

[stuey]

"Straight" acetone, no (as a general rule): however, nail-polish remover is a very diluted from of acetone. As always, there are no hard and fast rules: sometimes, experimentation is of the essence.

[Answerprancer]

I'm pretty sure water (eventually) softens cyanoacryllate ("super") glue.
Try leaving the affected part of your specs soaking in a glass of water for a few days.

As an aside, recently I had to buy a new bezel (the brass ring that goes around the dial) for an antique clock I was restoring as it was missing it. The new one came looking all gaudy and "blingy". So I soaked a cloth in nail-polish remover and gave it a good wiping. All of the shellac/varnish type shiny coating came off and left a nice dull finish.
