Let's see, Barry. Three levels:
1. Vision correcting devices that are regulated to be deemed safe and effective by professionals and regulators (i.e.: regulated market)
2. Vision correcting devices that are barely regulated to be deemed barely acceptable by professionals and regulators
3. Vision correcting devices that are completely unregulated, and the acceptability is up to the end user (i.e.: completely free market.)

We all agree that level one exists, and level three exists, and always did on the black market and in the third world.

You're saying we need level two, because we can cut out some expense by bare-bone-sing the professional input, regulation and oversight, and that this will save consumers money, and that it's a good thing. Right?

You're saying that practicing vision care and manufacture and supply of vision correcting devices is over-regulated and you think we need freer markets. Right?

Does this apply to Pharmacy? Surgery? Cosmetology? Engineering? Law? Do you care to draw a distinction between your profession and these others?
