I think he's talking about literal dollar priced masks or giveaway sleep masks which are usually just a tiny piece of fabric around something more solid, which attaches to you by means of an elastic band; the band however resists falling/slipping by pushing on your eyeballs.

It sounds like your mask is a bit better, and probably more expensive that the parent means. I've gotten such cheap masks as giveaways and the few I tried were indeed unbearable for sleeping as it felt like someone was crushing my face.
