They don't outside of the US. A good portion of my eyeglasses (custom prescription, with astigmatism correction) have been <$10 drop shipped to the US from Hong Kong, frames and lenses included. The most expensive variations (Transition sunglasses, complicated plastics to be thinner, memory metal frames) were $70, frames and lenses included. Most pairs end up in the $20-$40 range shipped. All this $150-$600 nonsense in the US just pays for the retail space, the branding, the insurance bureaucracy, and rent-seeking by the Luxxotica cartel. The downside is that I don't get to try them on beforehand... but nothing so far has been totally unwearable, and buying six pairs for $200, as I did once, addresses that concern pretty well.
