The Clip is a standalone rearview mirror module that clips onto the eyewear you already own — prescription glasses, your favourite sunglasses, or safety eyewear. One glance gives you full awareness of what's behind you, without changing the glasses you love.
It's the TriEye rearview concept — born from founder Carsten Juell Fongen's near-miss cycling in the Norwegian mountains — adapted to fit almost any frame.
Built for cyclists and runners with prescription eyewear, commuters, industrial users in safety glasses, and anyone who wants to add rearview awareness to their existing frames.

Four ways to ride — one mirror that goes everywhere.
Which TriEye is right for you?
Same patented mirror, three frames.
Unfortunately I had to return the product as I am unable to see my bike computer screen anymore while wearing the clip on top of my prescription glasses.. No matter how I set the backlight on the bike computer (IGPSport 300T), the bike computer is unreadable and appears totally black.
Works well over my aviator style prescription bifocals. It took a little bit of trial and error to get the mirror aimed right but now I don't have to turn around to see what's behind me - I just have to turn my head a bit to the side and angle my head up/down a bit to clearly see everything behind me. I feel A LOT safer biking with the TriEye clip on than any other mirrors I've used on my bike.
These were everything I’ve been looking for, they fit over my glasses well, I can read my GPS without having to remove them, and I am much more aware of traffic behind me! Thank you for perfecting these!! Love them!!
When I first got them I was a little disappointed how small the mirror was, it took a little while to get it adjusted just right but now I love them, TriEye is so comfortable and works very well.
Garbage truck insecurity disorder is CURED by tri eye.wont ride without it!!!!
I purchased a pair of clip on over glasses.
Centre mounting is ok, however the clip on's tend to move around when cycling !
So when your wanting certainty about what's coming behind, you can't guarantee the mirror will be correct !
Would better to have clips either side as well as centre ??
Aweful. Total joke. Flip attachment for my sunglases. Worst customer service. No return instructions. You have been warned. Purchase a cheap rear view mirror attachment.
Hi Nancy,
We're really sorry your experience with The Clip didn't go the way it should have — that's genuinely frustrating to read, and we take it seriously.
On the return instructions: that's on us. They should be easy to find and clearly communicated, and if they weren't, we've let you down. Please reach out through our website chart or email and we'll sort the return straight away — no hoops.
The Clip is a small rear-view mirror that clips directly onto the temple of your existing sunglasses — designed to give cyclists a clear view of traffic from behind without ever having to turn their head. We'd genuinely love to understand what didn't work for you. But first things first — let's make sure you're taken care of.

The sun glasses are superb. The first time I wore them I just went “wow!” As I looked at a beautiful view the difference was amazing. I have the clip on lenses and I am still getting the hang of how to use the mirror and after 3 rides I have only now got the adjustment where I think it should be but I need more than a glance when I tilt move my head. I find the lenses work really well with a wide variety of light levels including quite low levels.
If you ride a road bike all you can see is yoyr left shoulder. Use only with upright townie bike or mountain bike. Don’t use for road bike.
That's a fair point for road cycling in an aggressive aero position! Many of our road cyclists find it works well once the mirror angle is dialed in to their riding position — it just takes a few rides to get used to. If you're finding it tricky, feel free to reach out and we'll help you find the setup! 😊
Loving the clipons, ordered a spare mirror which arrived in pieces. One email and replacement sent, excellent service and product
Really like your "TriEye" product because it's much safer seeing what's behind me rather than actually looking back. I highly recommend this to all cyclists!
Great product, does what it says it does. 👍
This is my second pair. Lost the first. And the week and a half I was without, I realized what a difference they make!!
So much safer!! Like others, it took 1-2 rides to get dialed in again, but now I hardly move my head, just a little tilt and I can see everything behind me.
Thanks, Tri-Eye!
Worked great on the very first ride. I highly recommend this product!
Very good mirror is easy to use
Only issue is lack of nose support.
As a spectacle wearer, I bought the clip-on mirror. It clips on well and stays in place while riding. It’s taken 2-3 rides to get used to it and get the mirror set properly but I am very happy with it. It is the perfect solution for me.
Having a rear view mirror is a big plus while riding my bicycle. Used it once so far riding uphill and downhill, so getting use to view was a bit different with each elevation of the ride. Although I wanted it to fit a bit higher on my glasses, the most stable position I found was fitting it all the way down and resting it on my glasses frame. Adding additional paddings on the clips might help but have not tried yet.
Overall it worked well. Have recommended it to several cyclists and rowers.
I have both the clear and polarized versions of the clip on and am extremely happy with both. I have no worries of the mirrors being knocked out of setting and checking to the side and behind me is a snap. Outstanding!
Got rid of the handlebar rear view mirror! This works perfectly over my prescription glasses
I had the regular bike Tri-Eyes, but need to ride with glasses now, so I switched to the Clip On Tri's. A little different setting up but works Great!
I have been using rear views that attached to my prescription glasses which worked okay and provided some security but the integrated ones on the clip ons are definitely an improvement, being lighter and easier to adjust.
I have the clip on version; because I need reading glasses. The Trieye works very well. I only have to rotate my head slightly to the left in order to see what is behind and to the left of me while riding my mountain bike. You have to remember to be looking straight ahead with your head up and not down , when viewing behind. The Trieye took me about 20 minutes into my usual 2 hour ride to get use to it. I would purchase the Trieye again and recommend Trieye with no reservations.
What a great solution so I don’t have to wear contacts. The mirror is decent and stays in place.
I must first say that I have been riding an old Peugeot road bike for 38 years, equipped with a Mirrycle rear-view mirror which has served me very well, both in monitoring traffic behind me and in keeping track of other cyclists on group rides. My new bike with modern brake hoods and internal cable routing will not support this mirror, so I was looking for alternatives and saw these glasses. I bought a pair of the clip-ons and also an Italian rear-view mirror that attaches to the left brake hood with Velcro. I was suspicious of the mirror mounting, but pleasantly surprised that I could get it secured tightly enough because the mounting plate matched the shape of the brake hood exactly, so there is no noticeable wobble. It does not provide quite as large a field of view as my old Mirrycle, but almost. The image seems a little darker, however. The TriEye glasses took a while to get the mirror adjusted just right. This might be easier to do with your bike on a training stand and other bikes parked in various positions behind it than under actual riding conditions, at least at first. The mirror is good at staying where you set it, even after putting the clip-ons into and removing them out of the case multiple times. Getting used to using it while riding does take some time. The information on their website warns that you will need to rotate your head about 15 degrees to the left in order to see what is coming up behind you, and I adjusted to that very quickly and easily. What I found more challenging was learning to tip my head up slightly to see further down in the mirror image, and to tip my head down slightly to see further up in the mirror image, but still, after half a dozen group rides, this became more natural. I have been very pleased with the brightness of the image in the mirror. I can see the expressions on my cycling companions' faces! However, for seeing things further behind me the mirror mounted on my brake hood is superior. I like the clip-ons because I can maintain the functionality of my regular trifocal glasses.
I ordered these over two weeks ago. Twice, I received the wrong product. I had to ask for tracking and updates. I finally received the correct product yesterday. After my first ride and getting used to them I I really like them. They work great.
