 I added an explanation of spherical aberration and the tendency of light to distort around spherical objects, as well as the idea of how fisheye lenses use this principle to do their thing. [[User:Darkwolf0218|Darkwolf0218]] ([[User talk:Darkwolf0218|talk]]) 01:01, 16 May 2023 (UTC)
 : Thank you, the spherical aberration discussion is much better than before.  Much better than the optics course I took where they consistently failed to notice that spherical aberration is because the '''lens is the wrong shape'''; it is an engineering problem not a physics problem.[[Special:Contributions/172.70.111.153|172.70.111.153]] 16:32, 21 May 2023 (UTC)

 Well, of course wizards have trouble with spherical aberrations. Spherical aberrations have antimagic fields from the central eye, that's a big problem for wizards. [[Special:Contributions/2A0D:6FC7:607:410:322D:24B6:5B43:618F|2A0D:6FC7:607:410:322D:24B6:5B43:618F]] 20:53, 23 July 2025 (UTC)
