Never heard of "UV glasses"? Would anyone have a link? / Roger -----Original Message----- From: colorsync-users <colorsync-users-bounces+graxx=videotron.ca@lists.apple.com> On Behalf Of Refik Telhan via colorsync-users Sent: Wednesday, January 15, 2020 11:32 AM To: Wayne Bretl <waynebretl@cox.net> Cc: colorsync-users@lists.apple.com; graeme@argyllcms.com Subject: Re: Effects of lens implants on color vision (Was RE: Human color vision) Hi Wayne, This is the expected behavior. The UV-blocking glasses typically suppress wavelengths below 400 nm. The OBAs in the paper typically emit blue light at 430 nm in response to the UV component of the light at 330 nm. While the glasses block 330 nm, they let the 430 nm and the rest thru.

Frist, I checked that the glasses do indeed mostly block a UV led flashlight, and start to darken. Then I checked the tint on both papers under fluorescent light with the undarkened lens, and the tint was nearly equally visible to me. -----Original Message----- From: colorsync-users <colorsync-users-bounces+waynebretl=cox.net@lists.apple.com> On Behalf Of Graeme Gill via colorsync-users Sent: Tuesday, January 14, 2020 11:54 PM To: colorsync-users@lists.apple.com Cc: Graeme Gill <graeme2@argyllcms.com> Subject: Re: Effects of lens implants on color vision (Was RE: Human color vision) Wayne Bretl via colorsync-users wrote: > Before I developed cataracts, they appeared to have a slight amber > tint, especially noticeable in natural outdoor light, but also by > placing them on a piece of white paper under artificial light. If the paper was cheap, then this effect may be mostly the lens blocking the UV that triggers the paper Fluorescent Whitening Agent.
