Will sunglasses offer any added protection against cateracts vs normal glasses?

A decent pair of polarized sunglasses will be far more comfortable on a bright sunny day (pretty much every day all year round here 😉), but I would suppose that the only extra protection they provide against UV would be greater coverage due to their generally more 'wrap-around' nature?

Of course, I could be 100% wrong in that supposition, enlighten me 😉

It really depends on what the hell sunnies are.

Regular glasses can protect from UV, but only if they have a UV coating or they are a certain material like polycarbonate. Regular CR39 plastic lenses have no UV protecting properties. You can have a UV coating put on to lenses, but you would probably be aware of this because you would have to pay extra for this feature. Also the material polycarbonate it is known for its impact resistance and it provides UV protection.
So regular eyeglasses can protect from UV if they have a special coating or if they are made out of a material with UV protecting properties. Although keep in mind most regular glasses do not provide the same coverage that sunglasses have, and when spending time outside nothing beats a pair of 100% UV protected polarized sunglasses!

That's what I had figured, thanks 🙂

As far as I am aware my lenses have the fancy UV coating (they're a kinda greenish/purplish depending on the light).

That's the anti-reflection coating - not necessarily UV protective.
