- Support The lens bodies themselves are a little dusty and worn - but that's kind of a given for seeing the phenomenon. Informative and clear. Adam Cuerden (talk) 20:07, 21 January 2016 (UTC)

- Comment – Nit — Lenses, not being sentient beings, can't "experience" anything. (Also, on my screen, the yellowing of the lens at far right isn't readily apparent.) Sca (talk) 22:01, 21 January 2016 (UTC)
- In most dictionaries "experience" can mean "encounter or undergo" applying to non-sentient entities. Also the lens on the far right (according to the file description) shows no signs of yellowing for comparison. Maybe the caption could be improved to indicate this? - Wolftick (talk) 22:41, 21 January 2016 (UTC)
- Undergo does not imply consciousness; experience does. Sca (talk) 00:56, 22 January 2016 (UTC)
- Fair enough. I would say it's in fairly commonly (mis(?) :-) )used as a synonym for "undergo" for non-sentient things though. Your mileage may vary as to how important that is. OED has [with object] and "the company is experiencing difficulties" [1] but I'd agree undergo is better. - Wolftick (talk) 01:47, 22 January 2016 (UTC)
