If you leave in warm soapy water for long enough it should soften it, and may come off. Hope that helps.

 

Not wanting to contradict mrtrout, but: If they are glass lenses, use superglue remover - if they are plastic, best take more care with your next pair.

 

If they're glass use small drops af acetone, but make sure it doesn't run onto plastic frames; also a razor blade might help if you're very careful. But if it's plastic, then a long or even several soaks in the warm soapy water or a trip to Specsavers for a reglaze.

Try using a different make with a better dispensing & application method before you start making the same mistakes again.

 

A rather drastic means of stopping your specs sliding down your nose!

Would also reccomend soaking in warm soapy water then rub with a pencil eraser. Worked when I accidently left my thumbprint (and some thumb) on a wine glass.

 

If the above don't work, nail varnish remover will but may damage a plastic lense not sure.

 

Many thanks for the replies. I will let you know the final results of your suggestions once I have had a go at removing the superglue.
This type of problem is an age thing....... I was tying some minkies when I put my hand up to wipe some excess dinner from my chin, missed and smeared some glue on the lense. It will come to you all one day.
