+Sunglasses review
+I have always wanted to share more information on my experiences with sunglasses. Here is my opinion. If I had to only buy one pair, the clear winner for me from the below reviews are the Julbo Nomads. A combination I might do is the 2% lenses from NoIR in a Julbo Nomad frame; this could prove to be the best pair for me. The base curve on the lenses will fit into the Julbos. Base curve 8.
-{{tag>light}}
+Julbo Nomad frames with Spectron 4 lenses (5% light allowed)\\
+Where I Bought: I bought mine at REI, but there are a few online stores to get them cheaper, do some Googling :)\\
+Specs: Block 95% of visible light, up to 70% IR from what I can find.\\
+Comments:
+  * these provide the best fit to my face, and provide plastic side deflectors for peripheral vision.
+  * the lightest frame
+  * they do not slip easly, if ever
+  * all day comfort, I hardly notice I am wearing them most days
+  * I wear them inside, watching tv, using the computer, while at the office all day
+  * I wear them outside, for daytime driving, walking around, getting the mail, etc... I will wear them at night if I am not driving
+  * I am wearing them as I type this
+  * a darker lense could be needed on sun intense days outside
+  * more natural colors, as they do not block as much blue as NoIR
+NoIR Style #35 frames, I will review the lenses separately\\
+Where I Bought: NoIR Medical
+Comments:
+  * slip very easily, if I look down, I can expect them to slip down my nose
+  * they are noticable while wearing. I will get slight irritation where they rest on my ears
+  * they do no block as much light around my eyes, side, bottom, above, as the Julbos
+NoIR 10% lenses with Style #35\\
+Specs: Block 90% of visible light, all IR, blue light\\
+Comments:
+  * I will wear these around the house when the lighting is too dark to use the Julbo Spectron 4s
+  * I test drove these for a 2 days at the office, same lighting conditions each day. and They do not provide as much relief as the Spectron 4 lenses
+NoIR 40% lenses with Style #35\\
+Specs: Block 60% of visible light, all IR, blue light\\
+Comments:
+  * I have found these useful while driving at night to protect my eyes from oncoming headlights
+  * these stay in my car for night driving, clear winner for driving at night
+Ray-ban RB3217 frames with B15 polarized lenses:\\
+Where I Bought: Sunglass Hut (returned too)\\
+Specs: Block 85% of visible light, not sure about other spectrum, lower IR than the others\\
+Comments:
+  * I do not recommend these for the MP. They are ranked below the NoIR 10%. They do no block enough IR, and the polarized is a horrible choice for computer use. As LCD monitors do not mix well with polarization, depending on the tilt of the lense, they screen will go black.
+  * As a matter of fact, I had a heated discussion with a sales rep at sunglass hut about ray-ban, and the best they will do is block 85% of light, and not enough IR blocking. This is reasonable though, as they are tuned for a great optical experience, not for the MP :)
+  * Hands down best shades for fishing or golfing :), but not for MPers

+Welding glasses come in various shades denoted by numbers; #3 & #5 seem quite common. Permissible light transmission for each shade is governed by various standards (ANSI Z49.1-1967 in the US & EN169 in Europe).
+A few weeks ago I found out that the transmission of visible light for #3s should be 10-15%, and for #5s 1-2%, & reasoned that welding glasses would also have to block UV, IR & blue light - welding arcs are blue-white and hot.  But I wasn't able to confirm this.
+Today I found these figures from a US manufacturer (Elvex):
+UV protection 99.9%
+Blue light protection 99.7-99.9%
+IR protection 97.5%
+Visible light transmission #3: 10%, #5:1.3%
+(see http://tinyurl.com/y9e399o)
+This is significant because:
+a) welding glasses may offer equivalent (or only slightly inferior) protection to NoIRs.
+b) welding glasses are cheap (eg $7.49 for #3s here: http://tinyurl.com/yeozthu)
+c) NoIRs aren't available in China & would be considered expensive here. Lack of suitable/affordable eye protection could cause problems with the WCH trial. Welding glasses could fill this need.
+I understand that MPers develop varying degrees &/ types of light sensitivity. So until quite a few people have tried welding glasses it'll be difficult to know how well they work for us.
+But if you already have eye protection that works for you & feel like trying something different, here are some possibilities:
+- Elvex SG25-W3, SG25-W5 (Fitovers? PC mirror/NCB grey lenses offer less complete protection but might be OK for some; see link above)
+- Sperian Millenia 1006405 (#3) & 1006406 (#5) (Wraparound style - called Bacou-Dalloz in Europe I think)
+- In Europe: Lux Optical Visilux 60405 (#5* fitovers) /Soudlux 60820 (#5)
+I plan to try Millenia & Visilux models. If you try any welding glasses & have feedback about how well they work - especially compared to NoIRs (or whatever) - I for one would appreciate it.
+* Visilux 60404 transmits 3-8%, Visilux 60403 transmits 8-18% of visible light. These sound like #4s and #3s respectively, but the manufacturer's page doesn't explcitly state this anywhere I could find. See http://www.lux-optical.com ,"welding protection" & "the overglasses".
+Ok - for people in the US here are some online stores selling mainly wraparound styles in IR #5 (~2%), #3 (~10%) & #2 (~37%) from $6.15:
+http://www.safetyglassesusa.com/ir-protection.html
+http://www.safetyglassesinc.com/Safety-Glasses/Filtered-Safety-Glasses/
+http://www.discountsafetygear.com/safety-sunglasses-green.html
+If anyone finds sources of IR #5 fitovers, &/or links more convenient for people outside the USA please post them.
+Prescription lens wearers could use some Uvex products with a bit of help from an optician. "Rx inserts" are available for Uvex XCs** which come in #3 and #5. It might also be possible to retrofit Uvex Horizons*** with clear or lightly shaded prescription lenses to get a convenient (but perhaps not terribly attractive) flip-up style.
+(If you decide to buy some, please confirm the glasses are "IR3" or "shade 3" & certified for welding protection first - some vendors' websites are very vague on this.)

+  * $19 - see http://www.safetyglassesusa.com/brandnames-uvex-xc.html, near bottom. Note also availability of inexpensive IR #3/#5 replacement lenses for Uvex XCs.
