Because the mirror does not protrude much, if any, beyond a bicycle rider's head, a rider must turn their head to see the road behind. This means that the mirror does not provide the kind of constant situational awareness that I would like, or that a bike mounted mirror could provide. This means that the mirror is only of marginal utility. The light-sensitive, darkening lenses work well, however.

I replaced the mirror in my glasses with the larger version. The mirror itself gets five stars because it really does make a difference in how much you can see behind you and more to the edge. It does, however, have a hard time fitting in the case with the larger mirror. I'm willing to live with that.

I have used these for my walks. I bought them because I almost got hit by an electric scooter while walking on the sidewalk. It is real nice to be able to see what’s coming behind me. I adjusted to the mirror very quickly. Great product.

It is hard to get an angle where I see behind without staring at my shoulder — I have to contort myself to see. It’s not that fictional

I just came back from my first ride with Tri-Eye. Given that it will take a few rides to get to used to it, I will still give first impressions. First of all my wife and I ride as enthusiasts, Bike touring and fitness and we have been using mirrors for years. We would not leave on a ride without one. We have been using the Bike Peddler 'Take a Look' mirror that clips on the arm of your glasses. The purist cyclist look at you at a coffee shop like you are a nerd and I've heard many of them say stupid things like ' I just KNOW when a vehicle is approaching" or " it shaves too many watts off my power" ,etc. etc. The same cyclists are naieve about many motorists as they don't know how fast a car is approaching, how close they with brush you by, it there are mulitple vehicles, or if they are going to pass close to you on a hill pushing you over if there is no shoulder. Mirrors should be mandatory for cyclists in some form or the other in all developed nations as far as I am concerned.

There, now that you know how I feel, I'll move on to the review. We sought out a new mirror as our mirrors are scratched from about 10 years of use. Up came Tri-Eye on the search engine. It looked novel and got great reviews . A few factors were involved in the purchase. I needed a new prescription and I was limited in cycling glasses because of the strength of them. My old glasses were actually just a safety glass frame with darkening lenses. The cost of buying a new larger frame for wind and other was going to run about $700-800 CDN. Plus the cost of the arm mirror another $40. So the Tri-Eye came in as a bargain. For $287.00 plus tax which included the prescription lens insert and with photochromatic darkening. Lenses at the local Costco just ran about $150. So all in it was under $500 with taxes. For which we are a leader in in Canada:(:(
So here are some categories and observations

Packaging and Case- Good sturdy case and pouch included

Style- They look great, and well done with the Norwegian logo on it.
Comfort- They never slipped at all, I adjusted the nose piece once and left it. They are light and hardly feel them on my face. My old glasses I had to have a strap to keep them in place

Wind- Great at stopping watery eyes and wind. It was 45 km gusts today and I felt nothing in my eyes.

Sunlight- It was an overcast day, so I am not sure about the darkening on a sunny day yet, but today was great

Mirror- The field of view for this going from the other mirror we used, is a about half as much. If you have never used a clip on mirror before you will have not idea and these will be a game changer for you. However the mirror is so much closer to your face than the clip on kind, its' hard to get your cheek out of the view or your jacket ( if it is floppy in the wind) I stopped about 8 times to play with the mirror and the adjustments are so miniscule but they make a big difference. I'm concerned about putting them in teh case and it moving so slightly before the next ride. I recommend you take an hour for an 'adjustment ' ride before trekking off and another time and stopping to play with it .

Overall a great product.good value, and I am happy to see so many getting mirrors!
I will keep them and gradually get used to them the field of view, but I am sure they will never measure up to a clip on that I have been used to.
The other advantages and costs win the day.

The only reason I don't rate the product with five stars is I hope they can design a rear view mirror that locks into position once I set it for the right viewing.

Immer wieder gerne

I don't ride without my trieye photochromatic glasses now. Specially in nordic weather where its unpredictable, i recommend the photochromatic so that you dont have to change the lenses frequently. I als recommend changing the default mirror for the bigger 'rowing' ones.

Disse brillene har virkelig endret roingen for meg. Tidligere har jeg vært nervøs for å treffe bøyer, land eller andre båter, men den beskymringen er nå helt borte. med disse har jeg full oversikt og full kontroll. Ror du, er dette en investering du ikke vil angre på, de er verdt hver eneste krone! Fungerer også fint til sykling, selv om man må være litt ops på blindsoner. Har selv hatt de i nesten et år, og må virkelig si at kvaliteten og funskjonaliteten til disse er helt eksemplarisk. Føles fortsatt som om de helt nye, og bruker de seriøst hver eneste økt på vannet.

I feel much safer riding now. I don't have to keep looking back. It makes it easier because you know how it is. It's hard to hear when the wind is blowing while you're riding thank you very much. I really appreciate what I have and what you sold to me.

j'ai hésité au début croyant que c'était gadget, mais non ce n'est pas du tout gadget, c'est franchement génial, une fois réglé ça ne bouge plus, ça ne vibre pas et les lunettes sont belles et très confortables, je ne regrette vraiment pas mon achat

These are my first trieye sunglasses and the work perfectly although I did buy the bigger mirror and changed it over as soon as I received it....Just what I needed....

Lightweight, full eye protection and it tints fast. The key is to find the right placement that doesn't slip. Once you find your spot, it's the bee's knees. Just a slight turn of the head is all you need. Also, I ordered the larger mirror with my order so I could compare immediately without having to order separately. Glad I did. I prefer the larger field of view and It's a great compliment to back-facing radar.

The easy view behind me is very useful for hiking, walking my dog and bicycling. Particulary with ebikes adding danger to the bike paths and rarely wanring that they are about to pass at high speed, my glasses warn me when they are coming.

Second pair for me. I use these for late in the day rides when I will finish at twilight. They work perfect.

Fitting in the prescription insert requires a little fiddly skill. A small screwdriver, a fixer's mindset to assemble a two-piece puzzle. My optician, new to TriEye, became my superhero; I thought I would merely pick up the prescription insert (–8 diopter lenses fit BTW), & do it myself. But she loved the concept so much, she put it all together! Now I have prescription bicycle glasses that I want to use in many outdoor contexts.

Excellent riding glasses. Way better than the helmet attached mirror.

Good

I am a first timer after having tried helmet mounted and handlebar mounted mirrors for many years. It does take a minute to get used to them - head up and slight turn to left. I like the depth perception way better. I went with the oversized mirror and sm glad i did. Impressed the the photo chromatic lenses - so far so good

I love my trieye sunglasses . I just purchased a new pair wity pink frames . The Safety of riding and being able to quickly glance at the mirror to see cars or what’s behind you is incredible. I have had several friends purchase and I always have other riders ask me about them . They are a must if you are a cyclist !

Polarized glasses are comfortable and provide excellent coverage around edges. I’ve used mirrors clamped to visors for years and had to carry spares. Love that the trieye mirror gives good visibility and doesn’t fall off.

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!

I had a pair similar to this but unfortunately lost them on an ambulance ride after a crash. This time I ordered the ones that are photochromatic but still with mirrors on both sides. Have not gotten to wear them yet as I am still off my feet. Cannot wait until I can ride again with these glasses.

I’ve been riding a bike for exercise for several years, since I had to taper down on my running (which I had done for 45 yrs). I received my pair of Trieyes last March as a bday present, from a non-bike rider. I had never heard of them. But after using them, I found them to be invaluable. I wouldn’t consider riding without them. This past holiday season, I purchased a pair for my brother & another pair for a close friend. I want us all to be safer when we ride & you should too!
