LUFFNight Driving Glasses Clip On | Polarized Anti Glare Night Vision for Men & Women | Over Prescription Glasses to Reduce Headlight Glare and Brighten Vision

Really impressed,with the delivery, packaging and the product. Delivery was as promised, the product well packaged in a strong cardboard container, small enough to fit through my letterbox.The lenses came in a smart hard backed case with a cleaning cloth.They didn’t fit so well on an aviator style of frame due to the design of the frame but they fitted perfectly onto a different pair. The clip is hinged to allow easy fitting.The lenses reduced a lot of glare from on coming headlights, the halo effect was much less. Much safer for night driving.

These are not truly polarising glasses, as I have demonstrated by rotating a proper linear polarising filter in front of them. What happens is that the yellow colour appears and disappears, in other words it is only the yellow filter that is acting as a weak block to polarised light in one direction. I would expect true polarised glasses to completely block when tested in this way, though I have no experience of other glasses. These come with a little test card that you rotate as a demonstration, though it does not say what it is supposed to demonstrate as, again, the image just goes from neutral to yellow! Some say these work well for night driving, and as they are cheap I will try them for this as they are not very dark and may well reduce glare, but I note that they come with no guarantee that they reduce UV - a requirement for sunglasses if they are to reduce risk of cataract formation. PS. A report in New Scientist this week (10th Aug 2019) says that research has shown that when tested in a simulator against oncoming headlights most people said they could see better with yellow glasses on (they are supposed to cut out blue light which scatters in the eye more than longer wavelength light) but were found to miss dangerous events more than without them. The researchers concluded that yellow glasses for night driving confer false overconfidence but make drivers less safe. The problem of 'glare' is one that most people become more aware of as they age beyond 50 and which becomes a real problem for many at age 70. Young people are apt to think that 'glare' is a psychological thing - a desire to look away that can be resisted. Older people know that this is not the issue - scattering of light within the eye masks detail in dark areas, giving a 'washed out' view which can make it impossible to see, for example, a curb that is not painted white when faced with headlights at the same time (and some headlights are worse than other). Prince Phillip's recent accident in which he pulled out in front of a car that he did not see was probably caused by this - I wonder if he has had lens replacements. Unfortunately, most opthalmologists don't seem to understand this problem properly as they have not experienced it, and what they do not realise is that while it is often blamed on 'cataracts' it is in fact also caused by translucent floaters - blurry areas drifting across the field of vision that result from the breakup of the gelatinous body in the eyeball. In my own case I notice that glare around headlights often shimmers, a sign that it is caused by moving collagen fibres that are left by the breakup of the gelatinous body (which happens in all of us after about 50). These floaters are quite different from the black speck type floaters that are caused by tiny leaks of blood as the gelatinous body pulls away from the edge of the retina (usually ok but to be treated seriously as it can signal a detaching retina). The shimmering effect is particularly noticeable on rear lights, and orange streetlights, probably because the longer wavelength corresponds to the size of the collagen fibres causing interference patterns. Another common problem is 'ghost' images, often starting in one eye and caused by the lens in the eye starting to 'split' into sections that focus in different places on the retina. Though just referred to as catatact, this splitting does not cause cloudy sight as might be expected, but a double image in one eye when the other is closed. These splits tend to start at the edge of the lens (cortical cataract) as spokes that progress to the centre. If they affect the centre of the lens, then focus can become blurred when the iris is small, as when dazzled, and the nature of the double image can change according to light level and which parts of the lens are in use. The bottom line: not much you can do about light scattering to improve night driving, apart from lens replacement, which, though it can restore sight greatly, may or may not not eliminate all scatter depending whether you have bad floaters. There is no cure for floaters.

These anti glare clip ons exceeded my expectations. They fit perfectly on my glasses & don't look out of place. They are easy to use. They are good quality & make night driving so much better. The price was good. I would recommend.

These are a well-made product, nicely presented and packaged, in their own little case. There is a nice cleaning cloth as well so it altogether looks good when you open it.When driving in the daytime, I found it improved the contrast of darker colours helping draw attention to things that were moving and overlapping on the road and I was very pleased with that.However, there was very little polarising effect from the lenses, and when there was reflection from water on the road, the reflection remained as bright with or without the lenses clipped on. At dusk, the glasses worked well, but at night they didn’t limit the impact of oncoming headlights, and I could see more detail without the glasses than with them.So on a dull day on a long drive these clip on lenses might make the journey easier. But I found them not helpful for minimising reflections or or headlights.

As the days are getting shorter, my commutes are now more in the night time.I don't like travelling at night because of the ridiculously high colour temperature led/xenon lights modern cars are fitted with. Even though the drivers are using standard beam, the light from oncoming vehicles (and in motorways) dazzle me and sting me eyes.I needed a blue light filter, similar to apps like F.Lux etc.I came across these, had it delivered next day and boy what a pleasure it is to drive at night!!It is easy to clip on, lightweight and looks very good especially if you have rimless prescription glasses.I wish I came across this product 2 years ago, seriously this product is so much more valuable to me than the damn ps4!It has made my driving at night so much more comfortable!Thank you so much for this product!

These really do lower the glare from on-coming vehicle headlights.

As the description says, very good for night driving, the glare isn't quite 100% removed from headlamps, but a large chunk of it is, certainly takes the edge off bright lights. They are also super lite-weight!My only problem with these is that the lenses aren't Anti Reflection lenses. So you do get reflections especially when driving in built up areas with lots of street lights. The reflections aren't that bad though as the tint does take the edge off them.Excellent product for the price, would give it 5 stars, but the lack AR knocks a star off. Having looked around though after I bought these. I could not find a set of clip on lenses with Anti Reflection coating anywhere on amazon so don't let that stop you from buying these clip on glasses as they are decent for a low price.
