I live in north Manchester where they are referred to as specs (obviously)and gigs.

Are there any other regional slang words? And an explanation would be nice. Sorry I can’t explain gigs!

Bins. Have no idea why.

Midlands BTW.

gregs – gregory pecks – specs

Ah yes neilsonwheels – bins also in Manchester.

Isn’t bin’s a reference to ‘binocular’ as a source?

Gems. With a hard “g” like goat, not “jems”. Nope, no idea.

Also hear “bins” used here in Yorkshire.

Binoculars

In Glasgow I’d have said “gegs” rather than gigs.

I thought bins was as in bin lids

Sids, as in ‘Sid Littles’ in honour of the hilarious comedian – another North Manc one.

brakes – bin lid is rhymimg slang for a quid where I come from “can you lend us a bin lid ’til tomorrow.”

gogs here from goggles

Although having worn glasses from quite an early age I can assure you the most common phrase is “You speccy four eyed tw*t” and is usually accompanied by a thorough beating.

I can confirm that some 20 miles North from the OP it’s still ‘gigs’.
