CassandrichIs this a horrible idea? I just realized you can just, like, buy sodium lights and put them in indoor light fixtures.
Bye bye chromatic aberration. 🙃
Laurent Bercot@dalias making your world monochrome rather than changing glasses
@ska Believe me I very much want to find someone who will design & manufacture achromatic doublets or even better apochromatic tripets, and I will pay for it. Unfortunately no luck finding anyone. ðŸ˜

💲Paid@dalias You have chromatic aberrations in your glasses? That doesn't look right
@aris Yes. All lenses do; it's just a matter of (1) degree, which depends on Abbe number of the material and strength of the rx, and (2) sensitivity to noticing/being bothered by it.
@aris There are some exotic materials that would reduce it somewhat - sapphire or fluorite glasses - but nowhere near as much as achromats or apochromats would.
@dalias I'm used to the problem of chromatism in astronomic lenses of telescopes, there's it's not uncommon to have 3 or even 5 layers of fluorite (or equivalent) to reduce chromatism of bright stars or planets.
BTW light pollution filters usually help there because some of them heavily filter blue to close-uv. Maybe this blue-light-filtering fad would help on your glasses?
