ZILLERATENight Driving Glasses for Men & Women - Anti-Glare Night Vision Glasses for Driving, Polarised Lenses Filter Dazzling Glare from Headlights, Yellow Tinted Lens, Light Metal Frame

This review confirms and tells how to tell that, contrary to some reviews, these glasses are polarising, and shares communication I have had with the manufacturer. Bottom line, these work by mild polarisation, tinting and lens coatings. I'd say they reduce light intensity by about 15% which makes a noticable diffeence against modern LED headlights. They do not noticeably reduce ability to see detail on the road. Now to the details of what I found out.I looked into night driving glasses on finding myself increasingly dazzled at night by modern LED headlamps. Not a good thing, with the roads so full of potholes. I searched for Polaroid as that reduces scattered light. I also know from buying binoculars that lens coatings supposedly help to reduce incidental light. A third factor is that the tinting towards the red end of the spectrum (hence the yellow) cuts down the more intense blue end of the spectrum that is wearing on the eyes at night - hence why submarines would use red light.When I got my glasses, I tested them for Polaroid effect by rotating them against a pair of Polaroid sunglasses. I saw no darkening, whihc initially led me to think that other critical reviews were right, and that Polaroid was a false claim. However, my test was done in low light conditions as I'd been seeing if the glasses worked. I later repeated it in daytime against blue sky. This showed slight darkening, indicating mild Polarisation. As I looked into the matter more, I learned that heavy polarisation at night may lead to unintended optical effects with windscreens, thus, what these glasses do is seek a balance between polarising, tinting and lens coating effects.I looked into this carefully, because I saw various optician's websites suggesting that night driving glasses don't make much difference. This was contrary to what people's reviews said. It seemed that most of what I was seeing online was repeating other articles, and drawing on one study that has been criticised. Clearly, more research is needed. But in the meantime, I wrote to the manufacturers asking about their Polaroid claim and testing my suppositions. Below is their reply. I hope this helps others.They said: "Your night driving glasses use a Category 1 lens, which is designed to balance glare reduction with visibility. This means they won't achieve the complete blackout effect you might see with darker Category 3/4 polarised lenses. However, rotating them 90 degrees while facing a lit computer screen should still show a noticeable darkening effect, which verifies polarisation. While darker lenses block more glare, they can also reduce crucial light, compromising your vision at night. Category 1 lenses strike a balance, adhering to strict regulations (Directive EU 2016/425, harmonised standards ISO 12312-1:2013+A1:2015) that ensure safe night driving with a minimum light transmission of 75%. This means you get glare reduction without sacrificing clear visibility. While some may find the glare reduction mild, it adheres to safety standards and ensures clear vision at night."

So, I got Cataracts in my 30's. Two eye surgeries later (and two artificial lens implants later) I get serious haloing around bright lights and very little contrast in low light conditions.So, for me, they help a bit....basically because they cut some of the glare when driving at night without darkening my vision too much like regular sunglasses, and yellow tinted lenses do improve contrast in low-light conditions.These were also better quality than I expected from the reviews, feeling quite well made, basically your average mid-tier sunglasses.However, these are not magic. The wonders of marketing mean things like this are always massively over-sold, promising 'night vision' and 100% glare reduction, super HD vision.....and no, they aren't that. Basically, if you struggle on overcast days or driving in twilight, or you want something to cut headlight glare a bit, these help.... but they're not going to help you see better in total darkness, or completely eliminate glare because that would basically break the laws of physics.

Let’s be real. They don’t turn night into day; it would take military grade tech to do that. However, they do brighten your vision enough to make it easier to see in the dark. Headlight glare is not cut out completely (another reality check), but it is lowered to a more comfortable level. You will still have to flick your interior mirror up, or dim it, when you’ve got the idiot behind you so close that your cockpit is lit up like a torture chamber. On the plus side, if you control their speed by backing off from the driver in front to give yourself more room for reaction, they’ll be lighting up your way too, letting the night diving glasses have more light to brighten your view.An excellent product in all. They make night driving more comfortable by brightening available light, giving you more confidence, especially in inclement weather on unlit roads.

Very light and a good fit around the eyes. Comfortable to wear for long periods. Lessens the glare of LED lights but still bright enough to see everything. A tough case to put them in. You could play football with the case and I’m sure no damage to glasses !

Look great and fit well.I bought these as I cycle to and from work 17 miles each way.They are good at reducing glare from headlights not so great with high beams.Problem is when you cycle you breathe more heavily and (for me) this causes the glasses to fog up.Which makes high beams or those new cars with intensely bright headlights to near blind you making it very hard to see and hence quite dangerous to cycle when wearing when dark.Probably better suited to in car usage

I love these fantastic polarised night driving glasses. Sturdy and strong, very good quality and so far seem very durable. Spring loaded hinges on arms and very comfortable to wear. They make visibility sharper and give less glare on lights when night driving. Comes with a hard, durable, good quality zipper case, with a hook for useful storage, a one year warranty and cleaning cloth. They are lightweight, good quality and are a fantastic fit. They don’t move around so you hardly notice you are wearing them. From a woman’s perspective they are actually look very trendy and stylish to wear too and are a good unisex fit, style and size. They seem much more expensive than they really are. I am very surprised at the quality for the cost.
