I've found the best quality, high-index lenses to be what works for me. For me, polycarbonate lenses have a very narrow focus (i.e., like a yagi's beamwidth) so I was always turning my head to center in my lenses what I was looking at.
My monitors (two 19" 4:3 1280 X 1024) are on an Ergotron double swing-arm mount above my K-Line, which is on a shelf 4" (~9 cm) above my desk. I use Shamir Office lenses but I want to get a different pair that is optimized for the distances from keyboard to the monitors. Check out http://tinyurl.com/oa8erwf . I was recently diagnosed with a neck disk problem that is permanent. I don't know if staring at computer monitors for the last 33 years (accountant and ham) or bicycling was responsible, but I think this subject is very relevant. 73, Jim N7US -----Original Message----- I must also concur with Dale, et al. I also have a set of glasses I had the Optometrist prescribe, and I can not use my bifocals anymore, too much head movement... That was th best money I have spent in a long time. One thing you might consider is adding an AR coating to them. I use ONLY glass lenses, (no polycarbonate), and have them AR coated. The coating is finally coming off my bifocals after 5 years of heavy cleaning. The AR coating is wonderful if you have specular lighting events around your OP area. With an AR coating, if you clean your glasses right, (ultrasonic cleaner), you will not even see them... -- Thanks and 73's, For equipment, and software setups and reviews see: NK7Z ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
