The kafka-esque part is that they're well aware of the issue, because many of the lens companies (hoya, zeiss) have come up with "myopia control glasses" which are basically just minus lenses but with reduced power on the periphery, which they'll gladly sell you for added markup. It's no surprise that these are better than full-on minus lenses for close work, but you know what would be even better? Telling children to remove their glasses when using the computer or reading. But that doesn't bring in any profit.

Special scorn should be directed towards those that prescribe glasses for young kids for something as low as 0.25 diapers. And those that prescribe unequal power two both eyes rather than advising patching to equate both eyes.
