Older people still use the word spectacles sometimes. And anybody might choose the word as an occasional variant. But, on the whole, the word glasses is far more common.
Since the 1960s there has been a steady increase in 'glasses' and decrease in 'spectacles' in terms of frequency of use, both in the USA and the UK. The decline in the USA has been greater, but statistics show it is still used in the USA. (Ngram viewer by Google will give the statistics)
