If you wear varifocal glasses. I bought these from Aliexpress. They "Claimed" they were progressive lens. They were so cheap I thought what the hell, give it a go - expecting them to not work at all. But, colour me shocked, they really do. My presciption is +1.25 with +1.75 addition. So i ordered the +3. Far, mid and reading - all work. I mean, they probably no substitute for proper prescription, but as a spare pair, a change of look, they really worked, for 3 quid. https://www.aliexpress.com/item/1005007506952580.html?spm=a2g0o.order_list.order_list_main.15.36be1802nvX9n8
