Third EyeOn-Lens Micro Bicycle Mirror

I hate writing a bad review, but this was THE WORST purchase I've made online. I have used a mirror attached to glasses for years, racing, cross country, centuries, etc. This seemed to be the next best thing. I couldn't put it anywhere on my glasses, (3 pairs) without it hitting my eyelashes, no view rear view. After and hour of futzing with it I just threw it in the trash. Maybe it works with flat glasses, but anything curved is a no go from my experience. Those that had had good luck, good on you. I couldn't ever recommend this.

Well, I got a road bike last summer and started going out about once or twice a week. One of the first problems I encountered is looking back over my shoulder for cars. Every time I looked hard left, I felt like I was getting thrown off balance on my bike - no good. So I told my husband (an Ironman) that I needed a rear-view mirror. He said I'd be a dork out on the road with it on my helmet - haha, so I couldn't do that. I gotta look cool. This was the perfect solution. I've been riding now for a year, and this whole summer with the Micro Mirror and I love it. The blind spot it creates is not a problem at all and is forgotten about 30 seconds into a ride. It really works, but I would say, if my riding partner is a distance behind me, I can't see her very well. It's great for seeing cars though! I gave my glasses to my husband on a ride to show him how the mirror works for me and I used his glasses and I realized I had grown so accustomed to the mirror that I really wanted my own glasses back. I only have to turn my head a very little bit to see behind me. I do have to adjust my mirror every time I go out on a ride because it gets bumped when I put my glasses away.I also received an empty package when I ordered it. That was bizarre, but the amazon rep. was very helpful and I had a new package in the mail 2 days later.

Really wanted this to work. On the plus side, I had no issues using the supplied adhesive dots, and had no issues with the mirror pivot (never broke and was easy to use)."Too small" is over simplifying the issue. The mirror (mine, at least) seems to have a small amount of magnification. Looking in it while wearing glasses, with my partner standing about 15 - 20 foot behind me, their face nearly filled the mirror area. I wouldn't be too surprised if that wasn't the intent / this was a flaw, but things were very clear in the mirror. It's just that viewing such a small area makes it really difficult to quickly figure out what big things are going on behind you - which is the whole point of this thing (is a car approaching?).I used it on some fairly wide glasses (Zenni SKU# 232924) and placed the mirror nearest to the edge of the lens. Looking at the mirror is somewhat of a struggle. Looking through the mirror for a few seconds causes eye strain issues. I'm assuming that angle is too extreme for me to use - I would have to move the mirror inward and/or away from my eye to fix that issue.In that position, it certainly isn't able to see directly behind me. It's about a 30 degree angle off directly behind me, so I have to turn my head an awkward amount before it could even see cars coming... at which point, I can just turn a bit more and use my eyes to look back. It's not like I can focus on anything in front of my while trying to aim the mirror backward and peer through that tiny circle.IMO, this *might* work for me if it were a MUCH bigger rectangle that covered the entire edge of my lens. It'd also help if the pivot part wasn't so thick - that moves the lens closer to your face by over 1/8".It is super light weight, doesn't get in the way, has a very clear mirror, stays in place well enough, and is easy enough to adjust. But if you're not worried about looking like a dork, try the Take A Look mirror first.

The mirror itself is great and even has a cute little pivot. I love the idea, and wanted something like this for a while (mainly for walking, so I am forewarned whenever some knucklehead on a Bird scooter is about to blast by within an inch of me at 2000 mph, as seems to happen more and more frequently these days). This device comes close but doesn't quite cut it for 2 reasons:1. The glue-dots they provide are ineffective. I needed 3 of them just to get the thing to stick to my sunglasses, and even then it was quite loose and clearly would fall off in a matter of miinutes. I understand there's a fine line to walk here in order to secure the thing without damaging the glasses and still allow it to be removed. But their solution doesn't work. My guess is that you'll need to use some sort of stronger bonding agent, but then you won't be able to remove it without damaging the coating on your glasses. If the coating is only on the outside, you should be fine, though.2. How effective this thing is depends very heavily on your eyeglasses and head shape. If your glasses are no wider than your face, you'll have very limited rear-vision (and it won't be directly behind you). I found that even with the mirror mounted at the farthest point on the glasses, I needed to turn my head about 30-40 degrees to see what was coming up behind me. Better than nothing, but definitely not like a side-view mirror. This isn't their fault, of course. It's simple geometry. But it's important to set your expectations accordingly. If you have wide glasses which protrude from the sides of your face a lot, this mirror will be quite effective. Another possibility I have yet to try is finding a way to mount it on the rim.

I use the kind of mirror attached to my glasses.This little dot; its a very little dot. I could not make it work for me in any remote way. With training, and double jointed eye control; if i had hawk like eye sight, then maybe. It attached great, looks great, but it does not work for me.
