Does anybody know why solar cars and transitions lenses are actually a bad idea? 172.70.160.173 09:11, 7 May 2024 (UTC)

- The precise opposite is true. Grey lenses make all things - blue sky included - look greyer, as is perhaps unsurprising.

- I think the Transition lens issue is primarily that the bright light that can turn them dark need not be heading into the eye. With the Sun (say) off at an angle, it could be 'reacting' your lenses to dark needlesly, and reducing your ability to discern the things in front of you (which may be in shadow), working against the basic ability of the eye to adjust itself as per observed illumination.
- Conversely, a small bright light would not sufficiently darken the lenses but be still damaging to the spot(s) it falls upon in your retina (or do the "whole lens go dark" thing and still be too bright even as you can't see anything else beyond it). This might also be combined with the general secondary problem of potentially all regular sunglasses/goggles, that aren't industrial-grade or specific solar-specs, in that it might make it look safe to stare at bright things/skies through them but you cannot tell how much UV/etc is also being filtered out (some brands do have notable UV protection, but you really have to trust their claims/certifications – unless you have your own testing kit and knowledge of how much is good/bad anyway).
- I'd add that, but it needs a sharper explanation than I just gave. I'd like to make what's already there snappier, before that, plus correct the numerous typos and funny formatting (and lack of useful wikilinks), but will probably leave that to others with the time. 172.71.242.204 10:08, 7 May 2024 (UTC)
