Bought some sunglasses

[Musicgold]

Hi,

I read the following sentence in a book. I know that a possible variation could be 'a pair of sunglassses' or 'a few pairs of sunglasses'.
However, I am not sure if one can use 'some' even when they bought just one pair of sunglasses.

'I bought some sunglasses at the new store'

Thanks,

MG.
