Well, I just so happen to have a TANK-007 (395nm wavelength) torch so I could check to see if the 400nm spectrum was absorbed, making a video demonstrating that all included lenses *did* effectively block the 400nm UV lightwave!A good start, now how do they look in real life?Not so fast, first I had to figure out how to dismount the lens from the frame, unfortunately the instructions were no good. I searched online but I couldn’t find a step-by-setp video, so I figured it out and made a video that I hope helps people unsure with the process (it is at the end of the UV test video as Amazon only allows one video to be uploaded per review).YellowLiving in the countryside I found the yellow lens made everything more vibrant, the greens really pop out and that is about 90% of everything, so if you live out of town then be prepared for that. Alternatively, what little greenery there is in the towns and cities of today it should really bring it out - generally it lightens the emotions, inspiring a positive look to everything.BlueFar more subtle it just makes things look a little darker than usual, and works well on sunny days without distorting the surroundings too much.ClearLikely the last “colour” to be used once the others have cracked or gotten lost, like the Quality Street chocolates left in the tin that nobody wants at Christmas. The slight yellow tinge soon fades after adjusting to them, best for the easily confused.Brown (rainbow-coloured lens)I don’t know why this lens is referred to as brown because it’s every colour of the rainbow and doesn’t dim the view to brown at all. It gives everything that washed out vintage look that photographs from the 50s-60s-70s had, which might be the mood you’re in - it’s a favourite of mine as the colours uniformly distort; rather than heighten in any specific spectrum. However, with blinding overhead sunlight reflected from the pavement below, you’ll clearly see the perimeter of the lens in your peripheral vision, while other less dark lenses seem to not be as obvious.PolarisationThis one was the odd pick of the lot, but when you look at your computer screen (so long as you’ve not got the dark theme enabled in a beta release of macOS Mojave) you’ll immediately be aware of its effect. It just makes everything look a lot more blue and dark, and very useful if you need your wits about you on two wheels.The frame construction is quite sturdy and light weight and well padded on the top nose ridge. The lenses never slipped out of place, I doubt there’s any chance of that. However, I did notice a slight pinch behind the ears at the tips of the arms, after wearing them for short periods, but I’m not used to wearing specs.For the money I think they’re good value, ultimately a stepping stone to something more expensive if you want to take it further later on. Even if one lens breaks, four others take it’s place before you *really* need to buy a replacement.I don’t ever wear specs on my face, I usually look daft (I certainly don’t want to look like PC Principal), these have a universally appealing look to them, and I found that the blue ones suited me best. I made the choice for safety reasons as I’m usually blinded by the bright sunlight outdoors and don’t want to be dazzled on my bike, when the internet isn’t working.Good buy.

I was looking for a pair of clear glasses for running and cycling when the sun has gone in but I don't want flies in my eyes. I bought these and based on reviews and the extras you got with them and i wasnt disappointed. They arrived today and I've already been out for a cycle with them. I can't pretend they look great on me. They look a bit wide for my face but they serve a purpose so I'm not overly bothered about that and they still fit securely on. The case along is impressive with it's sturdiness as well as being big enough to store all of the spare lenses in because I half expended the case to just be big enough for the glasses and not all the extras. I also like the strap to fit around your head if you prefer to have that rather that the arms over the ears. The lenses are tricky to change until you get the hang of them but then they're no trouble. Likewise with swapping the arms for the elasticated strap. You just need to twist them out and twist them back in. Overall, a great product which is well worth the £12.99 I paid and i look forward to trying out the other lenses.

Sunglasses arrived on time, so prime delivery once again proving its worth.. the sunglasses are pretty good quality, they seem quite sturdy. Item arrived with the lenses as expected. Two of which state they are polarised, the other three state they are UV400. The set also arrived with a neck cord and an elastic head band. What surprised me is the case. As you can see in the photo, it is very good quality with foam inserts for the spare lenses to prevent them getting damages.. Very impressed!!

Wow... My wife bought some and I tried them on, liked the idea of a prescription insert and thought I’d buy a pair. When I did, they were on lightning sale so I paid £11 instead of £15Let’s be honest. At this price, it’s not bad for a sturdy case, two socks, strap and neck cord, let alone decent quality glasses, five different lens and a prescription insert..I had prescription lens put in from an Internet optician for £25 and these have become my regular never mind cycling sunglasses...

In the past I've always paid top dollar for Oakley sunglasses but have become disillusioned at paying over the odds for glasses which still seem to scratch so easily. You're basically paying fortunes for the brand name. Bought these cycling sunglasses on the basis of good reviews and price. They arrived on time and having used them several times on rides already I can't speak highly enough of the quality and amazing value for money. I could buy a new set of these every year for the next 10 years and still have change for the price you pay for one pair of Oakleys! Not that I anticipate having to replace them for several years yet.

Wasn't sure what to expect, but these glasses are pretty much perfect. They're a little bulky on the arms and certainly not the highest quality plastic (these aren't Oakley), but the fact that I didn't pay £160 for them gives them a lot of wiggle room. The carrying case is a surprising benefit, I can just clip it onto my beach volleyball bag. The different lenses are great, because it keeps the sand/rain out of my eyes even on cloudy days. The glasses are secure on my head, if a little long on the sides (not a significant problem at all). I've recommended this to teammates, as the product will fit pretty much any head type.In terms of return on price, I'd give this 6 stars if I could. Really excellent purchase.

For the price there are lots of things to like about these glasses. There is a good variety of interchangeable lenses which can be changed quickly. I don't need glasses but I can also see the prescription add in being very useful. Storage case is sturdy and will protect them well. They are a quite tight fit round the head, which they are supposed to be in fairness, but if you have a large sized head they might get a bit too tight at times. Can't really argue with them for the price against branded ones.
