LUFF Night Driving Clip On Glasses for Prescription Eyewear，4g

These glasses arrived on time and in a great little glasses case.They fit to my prescription glasses well so I’m now looking forward to trying them out at night against incoming bright lights

Wonderful clip on anti glare glasses. Easy to put on and light weight. Makes night time driving much safer.

Any attempt to flip up the unit causes them to fly off one's specs and as they are not scratch proof one has to hope for a soft landing. On the positive side they are effective when used in late winter daylight into dusk, into dark. They reduce headlight glare just enough and are quickly unobtrusive in use. In dull weather low level contrasts are lifted enough to be of use. They do, crucially reduce the lag time between peak 'blinded' and return to full night vision; age may not wither nor the years condemn, but for this older 55 years driving bloke all help is welcome.

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.

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.

Great

Whilst I accept that these glasses did reduce glare to some extent, they didn't really brighten everything as I had hoped. I struggle driving at night because dark to me is very black and I wanted something to even out the light levels, brightening the slightly darker. I have seen images of where this works well - but these glasses didn't do enough. As such, I have bought a more expensive pair from a different manufacturer and I will write this off to experience.

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.

He probado el producto en una carretera de doble sentido de noche y van muy bien amortiguan los destellos de los vehículos que vienen de frente las recomiendo

sehr gut und funktioniert gut

Je n'y croyais pas vraiment mais je les ai porté pendant 2h30 d'affilé de nuit sur nationale et autoroute : un réel soulagement au niveau de la fatigue des yeux, supprime le flash blanc des phares, clip très pratique pour mettre et enlever.

Essendo astigmatica guidare al buio è veramente fastidioso, devo dire che non fanno miracoli! Ma cmq un po' aiutano a smorzare i fasci di luce derivanti sia dalle altre macchine che dai fari!

Très bien
