Dioptre

I undid your changes to the article Dioptre. This article is about the unit of measure of optical power. On Wikipedia, each article covers one subject. Two unrelated subjects that happen to share the same name get covered in two separate articles. I don't think we have an article on dimorphic lenses yet. You might be interested in the article Frazier lens, which seems to be similar. We have many articles on camera lenses, which you can find at Category:Photographic lenses.--Srleffler (talk) 15:48, 19 October 2019 (UTC)
