Please don't move this page to "Aspherical lens" (which now redirects to this article). The universal term for these in the optics industry is (AFAIK) "aspheric lens" (or "asphere"). I just did a quick survey of a half dozen major optics vendors. Every single one uses the latter term.--Srleffler 12:54, 6 December 2005 (UTC)

I concur, the term Aspheric has entered into mainstream use in optometry. "The best ideas are common property." 02:16, 18 July 2007 (UTC)

This article could have sooooo much more information. I'm marking it an optics stub. Garvin (talk) 05:01, 13 January 2008 (UTC)

Stubs are by definition short. Anything longer than about a screenful of text is not a stub.--Srleffler (talk) 15:32, 13 January 2008 (UTC)

[edit] the current article is complete BS

Powerful words from someone who can't spell. I'm going to back out your change until you tell us what's behind it. Dicklyon (talk) 16:01, 27 February 2008 (UTC)
That may have been too harsh. His edit looks like it was done in good faith to me. Looking at the article, I can see that someone who primarily knows about ophthalmic optics might find it lacking. The section "Non-optical advantages of aspheric eyeglass lenses" is particularly bad, but I don't know enough about it to rewrite it. If CorvetteZ51 does know something about it, he may have a lot to add.--Srleffler (talk) 18:59, 27 February 2008 (UTC)
I thought it was harsh of him to call the article complete BS and then add unsupported claims to the lead, with a misspelling of a word that one knowledgeable in this field should be very familiar with. So I figured it was good to challenge him to fix it. Dicklyon (talk) 02:38, 28 February 2008 (UTC)
OK, most of the article is not BS. Eyeglasses only, aspherics offer a reduction in thicknesss of 20% or so, at the expense of increased off-axis astigmatism and different geometric distortion, as compared to a spherical base (front) curve.CorvetteZ51 (talk) 15:34, 28 February 2008 (UTC)
Do you know of a reference (print or online) that supports that? I don't doubt your claim, but it's helpful to Wikipedia to be able to back up the information that appears in the articles.--Srleffler (talk) 16:18, 28 February 2008 (UTC)
Apology accepted, as Stephen Colbert would say. So find us a good source and write that up. Dicklyon (talk) 16:16, 28 February 2008 (UTC)
my comments come from, reading hundreds of posts on Optiboard forum. I will try to cite something, but it is difficult, as there is much conflicting info, and lots of advertising copy. Apologies to everybody,BTW. None of my comments apply to photography lenses. CorvetteZ51 (talk) 15:56, 29 February 2008 (UTC)
That's what I was afraid of. We can't have you putting in stuff that learned from reading forums. That's just hearsay, not backed up by anything reliable. Dicklyon (talk) 18:07, 29 February 2008 (UTC)
D., you will find this interesting. http://www.opticampus.com/cecourse.php?url=lens_design/&OPTICAMP=f1e4252df70c63961503c46d0c8d8b60#asphericity

go down about 90% of the page, to 'Aspheric Lens Design'. Uf you have something more reliable, please indicate. CorvetteZ51 (talk) 11:55, 1 March 2008 (UTC)

Thanks, looks like an OK source. Dicklyon (talk) 16:04, 1 March 2008 (UTC)
