Now add in the fact that wearing minus lenses for close works restarts this process of hormesis, and you begin to realize that the entire optical industry ends up worsening a problem that they conveniently offer a "solution" to. Any minus lenses you purchase need to come with a big warning that they should not be used for distances closer than the focal plane.
- allisdust 5y agoYou will never see that happening. A $100 billion industry exists solely because of it. I feel sad whenever I see kids doing near work with glasses.
- krackers 5y agoThe 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.
- allisdust 5y agoSpecial 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.
