I hadn't thought of the cost, but the article does a good job of highlighting that. What I had noticed (in the UK at least) is how limiting the styles are by not being modular: opticians stock an impressive array of glasses, but it's incredible how inflexible it can be as countless times you find a pair that go well but then find there's some random flourish that ruins it - were the pieces modular (or better yet made to order by 3D printing) you'd get exactly what you were after - and then maybe I could just about stomach the pricing!
