Polarized Unisex Clip on Sunglasses for Prescription Eyeglasses-Good Clip Style Sunglasses for Myopia Glasses Outdoor/Driving/Fishing

These sunglasses are exactly as described in the product description.Unlike some cheap sunglasses, they ARE polarised. They fit my glasses well, with just a small overlap on all sides (although anyone considering purchasing will obviously have to check the dimensions of their own glasses. They are easy to put on and remove, with just a small, unobtrusive button to 'release' the arms that fit over the lens. The arms are also unobtrusive and do not appear as a distraction in the corner of my vision, as is the case with some other clip on sunglasses that I have tried.The construction seems to be pretty good but, like all other clip on sunglasses that I have seen, I would not expect them to survive any significant trauma - try not to sit on them!One thing to note: These glasses DO NOT flip up (as is claimed in an earlier review, but not in the product description). It seems that, if you want clip on sunglasses that will flip up, you will currently have to put up with having a much larger clip over the bridge of your nose.

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.

Have had real issue at night with dazzling headlights (they seem so much brighter than they used to be, and so many appear mis-aligned) with a developing cataract in one eye. These have sorted it... There's significant reduction in the dazzle effect now, not 100%. .. I'd put it at 90%. Feels so much safer now. Easy to put on / take off. Useful hard case and soft cloth. Recommend if finding night driving a problem... For price (less than a tenner) it's worth a try anyway, and if they work for you too they're way cheaper than what a optician would provide via prescription tinted glasses, I'm sure. Worth a punt therefore.

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!

Excellent!I got these clip-on sunglasses today and I am really pleased with them.I drove home (20 miles) in bright sunshine today with these on, and they did a great job. They really cut down the glare reflecting off other vehicles, and made a big difference.They are lightweight.Easy to put on.Stylish - I think they are the most stylish that I've seen. They don't have that (very) naff big hinge in the middle like others do. This is why I chose these.When fitted they are barely noticeable as clip-ons.My prescription glasses are rimless, low profile varifocals. These fit perfectly - see the photo's.Very glad that I bought them.

I bought these to keep in my fishing bag so I could see under water with the polarised lenses. Having to wear specs, I didn't want to buy separate frames and lenses, so clip-ons were the way to go. But I also didn't want to look like I was wearing clip-ons....uncool! These have a very small clip system which is virtually hidden once clipped on, so I bought a pair.They arrived quickly and well packaged in a protective plastic case with microfibre cloth. The lenses are light, easy to clip on and do a great job allowing me to spot fish. The clip-ons are fairly secure on my specs, but can be knocked off by a careless hand if not careful, but in normal use they are fine. I also don't look uncool. Well, at least I don't think so...Highly recommended. Now, where's that trout....
