the video tutorial suggested it would take three rides to get used to using the trieye mirror. i got used to it on my tri bike in one ride. it is true that it is hard to use while in aero position, but out of aero, it is easy. i have tried other rear view mirrors mounted on handle bars and helmet without success, for me the view from those rearview mirror mounts just ends up being a vibrating mess. the trieye provides a surprisingly stable view behind you.

I have many super high tech premium sunglasses that I wear everyday and for jogging and cycling including 5-6 d bike 🚴‍♂️ tours. Let’s name drop a few: Oakley, RayBan, Roka, Revo; some 200$+ a pair. An 18 yr old pair of Oakley Jawbones’ (Lance model) just decoated of late and had to be tossed after many, many 🚴‍♂️rides and races.
So I decided to give a pair of Tri Eye a spin. Have been wearing them for 2 weeks, was easy to get used to the mirror setup, have been very impressed w the quality, sharpness, and contrast of the lenses on 2hour bike rides. The mirror view is excellent and especially bright on late afternoon rides in low light conditions.
Previously, I have used a very good bar end Cateye mirror on my road bike; but on late rides, w leafed out trees on the road and dark colored cars wo the head lamps on, the vehicles are hard to see. Not so w the Tri Eye glasses; nice bright view, much safer for me. Will definitely get another pair, maybe the chromatic option……. esp. if the company could see their way to floating me a coupon… ha ha.
Thx, you folks have a super great product.

I've been a bicyclist for over 30 years. As a safety precaution, I always wore a rear view mirror mounted on my sunglasses. I want to see what's going on behind me whether it is cars or bicyclists approaching me. My TriEye eliminated the need for that setup. My TriEye works great. Thank you.

I feel safe and secure with my TriEye. I'm the guy calling out "car back" and when I'm on the front I can make sure I'm not riding the group off my wheel. I started using it for road biking but now use it commuting too because I feel blind without it. The photogray lenses are great for rides that start at dawn or for randonneuring rides into the night.

I have gone on several rides now using the TriEye sunglasses. After the second ride I got them adjusted just the way I wanted and the rear view visibility is great. I feel much safer on my rides knowing what is coming up behind me.

Great rear view mirror. So steady and easy to adjust. But another important feature is the nose piece. It is so comfortable and doesn’t slide down!

I've ridden for years with a mirror attached to my sunglasses. Trieye solves a couple problems with that.

1. At the of day, it gets too dim for sunglasses, but the photochromatic lens on these glasses works great, while preserving my mirror.

2. The attached mirror is bulky and I kept banging it into things. The Trieye is smooth and built-in.

Admittedly the external attached mirror gave a little broader view, but I'm ok with the trade-off.

I purchased TriEye based on the recommendation of ‘Cycling About’ one of the best YouTube commentators for bicycling. However, TriEye is even better than I had hoped as I added the spectacle insert which is inexpensive and works very well. The mirror is also high quality and works well. Overall a first rate purchase.

Takes a bit to get used to the new glasses, but worth the effort

I have been using different versions of TriEye since my participation in the Kick Starter Campaign. I have been satisfied with each of my three pairs I have purchased since then. All cyclists should own a pair.

Outstanding solution. Especially since I have neck issues. After a bit of trial and error and practice, it becomes second nature to check your 6 with a glance.

Work as advertised and didn't take long to get used to them. Much better than trying to crane my neck to see what's coming from behind. I was also able to apply stick-on bifocal lens to the glasses.

It was effort to find these, and expense to purchase them, and effort to learn how to use them, but worth every bit. They are great. I tried all the other rear view options on my mountain bike and this is the one that works best for me. Great quality, great fit, and of course the rear view mirror works perfect. Thanks!!

These are the best mirrors I’ve ever had

Exceptionally clear mirror. I feel much safer riding knowing I can see what is behind me at all times.

bought them for my wife and she loves them.

These glasses are amazing, clear rear view, gives you confidence in what is going on behind you on the road. Once you’ve set the little mirror it gives you a completely clear view of what’s approaching your bike, the mirror doesn’t move around much once it’s set. I can honestly say these glasses are a game changer. I bought clear lenses for night cycling and sunglasses for daytime , very easy to change over. Can’t recommend them enough

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.

Been a user for a while. The ability to replace scratched lenses is a great way to extend the life of the glasses.
I feel naked when I don’t have mine on.

Best thing I’ve done in a long time. Tried several different types mirrors and this by far in the best, clearest, easy to use mirror ever. Going to order another pair once the wife gets back on her bike.

It’s an additional tool … The view finder is fairly small. It’ll take a ride or two to gauge adjusting it so you’re not looking at your facial/skull line, nor the other side of route. It will never surpass your own riding instincts of hearing or anticipating a vehicle, but if you do anticipate, it will allow you to look up and out slightly (less degree than your own glance back) to hopefully anticipate an oncoming hazardous driver from behind.

I have been using a mirror on my glasses for eons, as a cyclist who rides 10,000+ miles a year, it is important for me to ensure visibility of my surroundings and be able to keep a defensive position on the bike. In addition to the mirror on my previous glasses, I also run mirrors on my bar ends and a radar system to detect things that I may not otherwise be able to see. A friend of mine pointed out these glasses to me. I wasn't in the market for new glasses at the time. However, last year with the mirror mounted to my glasses, the worst thing happened to me - I was hit on a trail with a blind driveway crossing and foliage covering it. All of the mirrors and radars in the world couldn't help me there. What was eye-opening, however, was that my clip-on mirror gouged a little bit into my head when I went down. I thought "good thing this didn't go into my eye". The glasses and mirror survived that incident, though my leg did not. I previously wore two different glasses - one with entirely clear lenses and ones which were photochromatic that didn't go fully clear, for pure daytime sunny rides. When I found that there was a photochromatic option for these, and they actually go to pure clear at night, I decided to give them a try. A week into using them, I had adapted to them so well that I had entirely forgotten that I changed my glasses. They fit so comfortably on my face, they are incredibly light, the clarity is amazing. They have worked so well in several Seattle-area riding conditions - sunny, rainy, day and night. People have asked me about them, and I enthusiastically recommended them. It's an absolute game-changer if you want the versatility and viewability of a mirror, without the liability of something dangling out in front of you. Moreover - and I can say this with pure confidence - with the photochromatic effect of these, I actually forget they are photochromatic. The reason I say this is because they are always at the right transparency level that I need given the conditions. If it is partly cloudy, they are less tinted. If it is very sunny, they are more tinted. In pitch darkness, they aren't tinted. They're always at the level I need to "see". The bonus is that they look absolutely great and are SO comfortable. I have the single-sided mirror, but knowing what I know now, I would have also enjoyed the dual-sided option as the mirror is not obtrusive at all. The lenses are huge. They are great at doing something that some of my other lenses have not - keeping bugs from flying straight into my eyeballs over the frame. I haven't had a bug go into my eye yet, and I've been using these daily for a few weeks. They're just perfect.

I’ve been cycling for 40 years and never liked using a rear viewing mirror. Always found them a bit annoying dangling in my field of vision creating a blind spot when I wasn’t using them for a rearward view and there was was kind of a stigma to wearing a mirror in the groups I was riding with.
After a few injuries and just getting older I couldn’t turn my head far enough around to see if a lane was clear to cross safely. Felt like a crapshoot half the time.
Using My TriEyes the mirror isn’t up in my field of vision and they don’t get knocked out of alignment as easily as a conventional mirror.
My feeling of safety on the road has tripled. Loving them

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.
