Polarized Sports Sunglasses,CrazyFire UV 400 Protection Unbreakable Sports Glasses with 5 Set of Interchangeable Lens, Sport Eye Protective Glasses for Women&Men in Running Cycling Fishing Golf

First review I've written for a while. For £12.99 this glasses there is an amazing deal. I bought sunglasses without a case and similar standard for the same price. These have a really good hard case that contains everything needed. I've not tried yet but everything looks good quality also includes a sports strap which I couldn't workout to start with but once I realised you just needed to twist the arms off and similarly twists Sports strapped in it leaves you with a pair of sports glasses where you don't have to worry about them falling off. So I was thinking we'll probably be good when I do any sports stuff in the sea as I lost a few pairs kayaking etc.

The media could not be loaded.  I didn’t realise, but should have checked that these were from a Chinese company, it’s obvious when reading the instructions: not because of the American English, but because of the wording:Lens type and color: yellow: "Improve visual contrast and provide more accurate video,so called "night vision Lens", especially suitable for driver use at night."...Warning: "we doesn't recommend colorful lens be used for night driving"Basically, use any colour you like, they’re all the same :)Before I took each lens out on a sunny day to see how they performed, I wanted to be sure that they did in fact block UV light (“UV400” so they claim). 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.

Having suffered an eye injury while playing tennis and advised to wear sports glasses in future, I bought these about a year ago and have worn them since then while playing tennis (they also make good cycling glasses). They are comfortable to wear, excellent clarity, and a wide choice of different lenses for different light conditions. Changing the lenses proved a little awkward until I learnt the technique, and now, no problem. Highly recommended.

lots for your money and looks good but you have to remember its cheap crap so don't be disappointed that they are definitely not polarised.the "night vision" yellow ones do not have any benefit in the dark, in fact better without them to be safe.I find that they distort vision a bit when car headlights coming towards you which can be a little annoying.nice case and lots for your money but don't expect a good quality product.They are just safety glasses that keep the wind out your eyes and look ok.

Excellent product. Perfect fit and I have a small head. Yet to test them on the road and off road so may do a follow up. I was not expecting the case and the way the items packed inside to be so good. Fantastic. Good quality case. Robust. For the price you cannot beat it. Am glad I bought them. One person said they came with no instructions but am sure they are on line. I will check. Overall I am impressed with them. The last dedicated cycling glasses I bought was in 1994 and they cost a lot more. So hat's off to Crazy Fire.

This comes with an array of different lenses including a polarizing lens. They're held in very securely but can be changed without tools. The hard case makes it easy to carry in a pannier with other things like a lock without worrying about damage.Not the most comfortable; the frames are flexible and while you're out you forget you've got them on, but they are a little tight at the sides - they're not going to fall off your face though.

Good value for money. When you compare these to the more expensive brands, you cant complain. They feel a little cheap when you first get your hands on them. But they are. They do the job. Great for someone starting out in the cycling world

These glasses are brill. Come in a hard storage case with clothe carrying pouch, lens wipe and 5 types of lenses. They are well made and so sturdy that I think you could accidently sit on the glasses without damage. All for £10.99 ! Bargain.
