I bought the dual mirrored glasses for cycling (as opposed to rowing) because I have a disability with my left eye which makes looking to the left while focusing quite difficult. To my surprise I can use the left mirror. Having the right mirror to do a quick check too gives me peace of mind that the lane to my left is clear. I have tried many mirror configurations (helmet, attachment to glasses, wrist and handlebars) that have all failed. I will be wearing these every time I am on the road

When I watched the review of this product, I was hesitant to get it because I thought it was a gimmick. So, to be honest, when it was on sale, I took a gamble and ordered it. Boy, was I wrong about this product? Now, I love it and use it for every ride. It will take a little time to get used to it because the first thing you want to do is turn your head around instead of slightly turning your head.

I love it

You have to get used to it. The jury is still out, but they are pushing for this review.

Riding has been a big part of my life. Looking backwards to cross streets or see where you buddy is has always been unsafe. Well these glasses work great and I'm so very happy that I have them. You will not be sorry

Good concept and does provide a reasonable reference for rear view. Took a lot of tweaking to find the sweet spot. Very well made and quality lenses. I like the ventilation as a design feature too. The mirror does diminish the overall field of view, which is slightly disorienting. I'll definitely wear these when cars present a concern.

Pretty useful rear vision once you get used to it. Happy with purchase

Takes a little getting used to versus a visor clipped mirror, but this makes bowing and singling SO much easier to see what's ahead. Whether practicing on a busy body of water or chasing down that next boat in a head race, this thing's got your back.

Even though the mirror of the Trieye is smaller than the rear view mirror I was using attached to my helmet, the visual field is more clear and bigger than what I had before. It has not been difficult at all to get used to. I feel very safe and confident in seeing what is going on behind me. Very much worth the cost and I recommend them wholeheartedly.

The photo chromatic function works great when going from sunny road to shady trail. The rear view mirror is much like the the door mirror on a car...a slight movement's up the right and voila, you can see what you need behind you. Love it!

Visibility with prescription insert is fantastic. Photochromatic lense is very functional. Stylish glasses. Used to have large rear view mirror attached to helmet. Grieve is more ergonomic it taking a little while to get used to reduced field
Of view and proper mirror adjustment. Feel I will get this right on next ride. Coupled with my Garmin Varia radar backlight feel very safe

Although I have a radar to alert me of traffic coming up behind me, it doesn’t tell me what or how many.
With TriEye, I can see what, who and how many. I love the ability to clearly see what is coming behind me or what has happened behind me. These glasses are nice looking and the integrated mirror makes me feel more confident with additional traction the trail/road.

I bought these for my husband for Christmas. He seemed skeptical at first but after watching the instructional video said they seem pretty cool. He won't get a chance to use them until spring but they will give me a little more peace of mind for his safety.

I have ridden with a mirror on my helmet for years, but my wife didn't like the look, so she never switched. I gave her a pair of TrEyes for Christmas, and after some adjustments, they're now her regular riding glasses. I also bought a pair for myself, and they're better than I expected, given the smaller field of view. I also have switched over to using these regularly, and feel that we're safer together.

Best purchase of cycling glasses I've ever made.

We got our TriEyes for Christmas and finally got to give them a test. So far we love them. The quality of the lenses and mirror are excellent. Thinks are much clearer and brighter. We adapted to the checking the mirrors quickly and it wasn't difficult. One comment from my husband is that he might like a mirror on both sides for those situations where he needs to see behind him on the right.

This is my second pair of Tri-Eyes. My first pair broke in a crash I was in, much to my dismay. I consider these an essential part of my cycling setup. I highly recommend springing for the photochromatic lens. Really nice to have when you start a ride while its still dark out and end it in full sunshine.

Takes a bit of getting used to as you have to tilt your head back in a way that feels unnatural to me on a drop handlebar bike. By the third ride I found them easier to use particularly when I got up on hoods -- still kind of difficult on the drops. Was wondering if it were possible to put the mirror in the upper left of the left lens instead of the lower left.

I have just received my glasses and am working to get used to them. So far the used of the glasses is improving or in other words I am getting used to them and the work great. I am glad I bought them.

I’ve only had a chance to ride two times since getting my TriEyes. The first time it was only so-so because my hair was not pulled back and was very distracting. The second time, it was awesome. I was riding on a hilly windy road and by tilting my head just a wee bit I was able to see so much more than I can see with my handlebar mounted mirror.

I have the large, dark lens (no photochromatic). I am a 5'10" male. I have used various helmet mirrors for many years and wouldn't ride without one now.
The trieye is much more convenient than the helmet mirrors (less dork factor as well). The actual glasses are slightly too big, I think, but maybe the presence of the mirror influences that.
The view in the mirror is my only gripe: I would like the mirror to be slightly higher up on the lens - it is a little uncomfortable to look down to the far bottom left corner. That said, the quality of the view is excellent.
One caveat: I use "Elvis ears" which are velcro strips wrapped around the strap by my ears - they reduce wind noise which is a factor for old guys like me who are going deaf. With the Elvis ears on the mirror view was significantly obscured. Once I removed them (just the strap) it was OK - it did encourage me to make sure the strap was firmly against the side of my face so as to not be noticed.
Overall: I like them so far (I adjusted within two rides) and will continue to use them.
For what they are they are a bit expensive so I hope the cost comes down as I would definitely buy more.

I do love the idea of this product. The lenses change so gently that you don’t even notice and the clarity of the lenses is awesome! However, my sensitive blue eyes would like them to get a bit darker. I wish the nose piece had a soft, adjustable and flexible fit. The fit is not as comfortable as I would like and the hard plastic hurts after a while. It leaves a big mark on my nose. The mirror is difficult to adjust. I have not found the right angle yet. It’s been a bit frustrating. Part of that issue is that my eyes don’t adjust to near vision very easily. That’s an age thing.. and not the fault of the glasses! I do love the idea of this product. I think many folks probably do and will enjoy it. It just is not working well for me. I will give them to my husband to try. Hopefully he can make use of them. I do hope you will continue to develop this product. I think it will be a great asset to the biking community.

I purchased a pair mainly to keep an eye on conditions behind. There is a small learning curve and after a few rides it will come pretty naturally. I have to turn my head maybe 15 degrees slight left to view behind me. This is so much better than turning your head to look behind you. The only downside I have found is that if you want to turn your head to check behind, the mirror blocks your view. The more I ride with them, the more I like them. They are now my go to cycling glasses and would highly recommend to anyone on the fence about purchasing a pair.

Love the way is really enhances the contrast factor, and ease of seeing objects to the side and rear while riding. Best I've ever used in my sixty five years of long distance cycling all over the world!

Multiple owner of these cycling classes . They never cease to amaze me I have several fellow team mates that have started using you products and all have nothing but great reviews!!!
