Reddit reviews Third Eye Eyeglass Bicycle Mirror

I have this little rearview mirror that clips onto my glasses when I bike. It's pretty dorky looking and people have told me that 'real bikers' don't use them.

But, once you get used to it, it's like having eyes in the back of your head. I feel naked without it.

I prefer helmet mirrors over bar-end mirrors for ease of installation and because your body will minimize vibrations that make mirrors harder to use. Out of the helmet mirrors I've tried, here's what I've found:

• Third Eye helmet mirror - Near garbage. Ball joint becomes unusably limp within only a few months of daily, all-weather use. 1990s versions use adhesive to stick to your helmet, so kind of a pain in the ass to set up or stick back on if the cold causes the adhesive to get brittle and snap off. Weirdly thick rim around the mirror. Newer versions use a forked design to slip onto a visor or eyeglasses instead, but given how well plastics do with wear and flexing, this just adds another point of failure. Wasted more time in high school on this thing than my time was worth, which is impressive considering I made about 25-50¢/hour working for the Boy Scouts during the summers only. On the upside, no vibration at all while it's still new and holds tight.
  
  
• Bike Peddler Take A Look mirror. Not that much more than the cheapo Third Eye model. Wire design highly adjustable. Mine's now moved to it's third helmet and outlasted the bicycle I bought it with. Larger mirror than the Third Eye model. Mine's 20 years old now, and the design on new ones is exactly the same as they were 20 years ago. A little on the springy side, can be a little annoying on rough surfaces as a result. Holds it's position extremely well. If you're going helmet instead of bar-end, start here.

Neither -- because it's all about the glasses.

I've used a few different styles of mirrors. I've come to prefer the eyeglass mounted ones. I've tried a few different styles of those. The ones I prefer are the so-called third eye model.

I used a glasses mirror (thank you FountainsOfDave for that link) for about four years until the joint wore out and the mirror started dropping every time I hit a bump. I liked it a lot - it sits in a convenient place and the image is clear. Downsides are that it's a little small and can take some adjusting to get in the right position, especially if you keep taking them off and on the glasses.

For the past month or so, I've been using a bar end mirror on my left drop. It's convex and shows more of the road than the glasses mirror, but it's a bit distorted around the edges and wherever it's set, it's set - you can't "search" the road behind you as well as you can with a glasses or helmet mirror by moving your head. The other issue that I've had with the bar end mirror is that if you're not on particularly smooth roads, the road vibrations make the image fuzzy.

After the first week of using the bar end mirror, I would definitely have said that I preferred the glasses mirror for the clarity of the image, but as I'm getting used to the bar end I'm actually starting to like it more and more.

I saw your Personal Rear View Mirror--I used to actually have one of those. It was about the size of a quarter and clipped onto the frame of your glasses. It was meant for bicycling (which is what I used it for).

Looked a lot like this one.

I wear glasses, so this one works well for me.

I have this mirror mounted on the visor of my helmet with the help of zip-ties. I have more bikes & glasses than helmets, so it works out best for me.
