phil Dean Posted January 19 Report Share Posted January 19 (edited) If this is really causing people problems have a look at this website www.uksportseyewear.co.uk he was a high st optician but got into supplying specialist eyewear for the Police and special forces. Sold his shop and now just supplies specialist eyewear. I struggle after a bike ride with watery eyes what ever cycling glassesI triedI still had sore eyes. He sorted me out with some specialist cycling glasses that half look like goggles and half like cycling glasses. They are 90% efficient certainly a lot better than before. He is very knowledgeable. The glasses are made in America and Europe NOT China . I have his mobile if it’s not on his website just pm me. Phil. Edited January 20 by phil Dean Quote Link to post Share on other sites

john.r.davies Posted January 20 Report Share Posted January 20 Roger, best you scroll on down to the bottom of the page you linked to, were it says, among other legal small print that negates any value to the opinions expressed, "This is an advertisement and not an actual news article, blog, or consumer protection update. This site is owned by Seth Media. " Perhaps you can find a real, unbiased study that conforms that "Night driving glasses have any value? John Quote Link to post Share on other sites
RogerH Posted January 20 Report Share Posted January 20 I think being pedantic is the flavour of the day here. Glasses that help one drive at night could happily be described as night vision glasses. Be it removing blue glare from HID/LED head lights or reflection of wet roads However if you do want night vision assistance you could go to this extreme NIGHT VISION But they may not remove the HID/LED Blue Glare Roger Quote Link to post Share on other sites
Clarkey Posted January 23 Report Share Posted January 23 (edited) "I was taught when learning to drive look to just past the end of your headlight beam kerbside that way you dont get blinded so much by oncoming headlamps." I too was taught this as a newly qualified driver back in the day , This work because only 3 degrees of your 180 degrees of vision is in focus How can this be so you say A quick test is the wrist you have your watch on , make a fist with the back of your hand facing you, now place the thumb of your other hand against the knuckles of the fist, look at the thumb nail and try and tell the time Edited January 23 by Clarkey Quote Link to post Share on other sites

Misfit Posted January 29 Report Share Posted January 29 (edited) If anyone is still interested in this, I had the yellow night classes before my ret detachment and cataract operations, they impared my vision further, when updating my prescription classes they suggested clear anti glare, that worked well for me. Now I don’t need prescription glasses I had plan glass replaced with the same anti glare, they work and the whole world isn’t yellow.

Ralph Whitaker Posted February 6 Report Share Posted February 6 For what it is worth, I got my night driving glasses from Amazon with next day delivery and have used them. I find no difference in general vision or ability to see at night apart from there is a definite reduction in glare from LED headlights. There must be truth in that it is to do with the blue spectrum, because now oncoming cars with "normal" headlights just appear to have a yellow tinge, but you can spot the moderns coming towards you as now their headlights are pale green in colour and intensity is reduced. Felt strange when I first used them, which was on a 150 mile journey back from the lake district the day after all the snow, but after a few miles forgot I was wearing them . Definite thumbs up from me. Ralph Quote Link to post Share on other sites
BlueTR3A-5EKT Posted February 6 Report Share Posted February 6 For those who are in the know. Peril Sensitive Sunglasses Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses have been specially designed to help people develop a relaxed attitude to danger. At the first hint of trouble, they turn totally black and thus prevent you from seeing anything that might alarm you. A double-pair are frequently worn by Zaphod Beeblebrox.

For extreme danger there are electro-optical devices that can switch from transparent to opaque in nanoseconds, called Kerr Cells. Where I worked they were used as extremely fast camera-shutters. - You might get tired of lugging the 2kV pulsed-power supply around but I'm sure those could be miniaturised now. Ours were in 3-foot tall 19-inch racks. Apologies for extreme thread diversion. Quote Link to post Share on other sites
Andy Moltu Posted February 6 Report Share Posted February 6 I guess the issue with filtering out the blue end of the spectrum to avoid glare/dazzle is that it may well mean we see less of what we need to when not being dazzled. The old yellow neon street lights have a poorer road safety record than white ones because drivers could not see pedestrians as well. Street lighting went over to white light as the costs came down. Even the French accepted that their yellow headlights were less good than white. The problem is some headlights now are simply too bright and mounted (legally) too high to limit dazzle.

I don`t think it makes any difference, I suggest that I can see further not dazzled than I can after having just been dazzled by a zillion candlepower. Even if the pedestrian is dressed all in blue I don`t think they would become invisible, just turn a nice shade of green . 18 hours ago, Andy Moltu said: The problem is some headlights now are simply too bright and mounted (legally) too high to limit dazzle. +1. I own up to having a car with HID lights, and all such lights have to be self levelling, but there are limits to the reaction time of self levelling units, and cars cresting a bridge or a rise in the road still dazzle. But even well adjusted lights can still be a nuisance due simply to the intensity. There was a reason why the wattage of headlamps used to be limited, and it was to reduce dazzle to oncoming vehicles, but it seems now that with LED and HID lamps that can put out 200% or more light with less wattage the old rules are not fit for purpose, and it is too late now to bring in new rules limiting the amount of Lumens Anyway, I for one will continue to wear my sunglasses when it is sunny, and my anti dazzle glasses when driving at night.

Trev Good Posted February 7 Report Share Posted February 7 Having followed this discussion for a while, especially as I wished to improve my TR6 lighting, I have previously noticed the following:- One modern addition to motor cars other than LED lighting is the auto dipping headlight. As I have recourse to drive many modern cars, I have been taking note of their dipping function.....the only one that automatically dipped it's lighting anywhere near when I would normally have flicked the dipper switch with oncoming traffic was an Aston Martin, could this delay in headlight dipping on most modern cars also add to the problem? Incidentally, I have chosen LEDs from 4sight Automotive as they supply the correct blue spectrum reduced headlight bulbs. Quote Link to post Share on other sites
Andy Moltu Posted February 7 Report Share Posted February 7 I agree, far too many of the auto dipping headlights do so far too late. Quote Link to post Share on other sites

Definite thumbs up from me. Ralph Hello Ralph I have recently obtained 2 different pairs of these yellow tinted, anti-glare, polarised lens glasses from different ebay suppliers. Last night driving in the dark and pouring rain I was able to try out the first pair. These were described by the e-bay seller as Unisex night driving glasses, anti-glare, polarised, HD yellow tinted lens. Made in UK, UV400, lens 65x40mm, bridge 15mm. Cost just over a fiver. The plus points: Like Ralph I could tell instantly which of the oncoming vehicles had 'normal' headlights and which had high intensity (LED?) lights. Most of the oncoming headlights had a yellow tinge but the high intensity headlamps were pale green. The dazzle was eliminated. Even the cars coming up behind did not dazzle via the rear view mirror so did not have to 'dip' the lever on the mirror to stop being dazzled. The minus points: The effect of wearing the glasses on visibility is best described as driving in France when yellow headlights were the norm. I have yellow beam dip adapters for the TR for driving in France. They give a yellow beam which is the same effect as wearing the yellow glasses. On well lit roads, motorways no problem but on rural roads on dip beam the visibility is slightly less. On main beam no problem. I have to say that the driving conditions during this trial were pretty bad with torrential rain so tested under less than ideal conditions. The other pair has lenses that appear to be slightly more yellow so I am guessing they might not be as good as the first pair when driving on rural roads on dip beam. I will try them out and report back on those. Conclusion: From this first trial I have to say that the glare from high intensity headlamps was pretty well eliminated. The downside being a slight reduction in visibility on rural roads on dip beam. I think that a very slight yellow tinge is enough to cut out the glare. Too much yellow would reduce general visibility. I wonder if it is possible to design glasses that just cut out the blue spike from LED lamps without the need for yellow tinting? On the whole I was quite pleased with the results with this first pair of 'night driving' glasses so will not be consigning them to the bin and will try them out again when driving conditions are better than last night.

Pedestrians and cyclists? Nah - just burn their retinas. Burn their retinas? Have you seen (not for more than a moment!) how bright are some bike lamps? This is the brightest and it's a bit bulky, but at 60,000 lumen: 'Normal' car headlamps -2-4K Lumen? But bike riders NEED this sort of illumination, as we are apparently invisible to most drivers, even in broad daylight while wearing DayGlo jackets!

RobH Posted February 7 Report Share Posted February 7 (edited) John - the vast majority of cyclists I see out at night have no lights at all, as well as wearing black hoodies with the hood pulled up ! The MAMILs are the ones with bright lights but they seem to favour strobing ones, though a large number of them also wear all-black strip.

Nah - just burn their retinas. Back to my comment about dog walkers now carrying and flashing LED pointer lights at the front of oncoming cars that are dazzling them. Cyclist that have bothered to have lights also seem to misunderstand the difference between being seen and dazzling other road users. Those not bothering to have lights maybe want to help with population control. Quote Link to post Share on other sites
