Sure, it's enough to pay for the materials (frames cost pennies, and cheap lenses maybe $1?).
But someone still has to cut the the lenses to size, and fit them to the frame. This requires both equipment and skill.
I don't think I've ever paid less than $15-$20 for prescription single-vision glasses. I've paid more even in the 'wholesale' optical market in Beijing.
$2 is easily achievable for reading glasses, which are mass produced with lenses installed at the factory.
