Review on Round Cycleaware Viewpoint Eyewear Mirror: Enhancing Visibility for Safer Cycling by Christopher Sullivan

I decided to try the product to see how it works. Given the cost, I thought it was worth a try. I'm a quality engineer with 35 years of experience in product performance and safety testing in the medical device and consumer goods industries. I have also been a sports and recreational cyclist for 39 years. I attached a mirror to my cheap, razor-sharp sunglasses I use for horseback riding. Assembly was pretty easy. First I placed the mirror on top of the glasses without removing the adhesive backing and looked down while placing the glasses on my face. I tried to focus on one spot on the ceiling to get a rough idea of where to mount the mirror. The curvature of the lenses made it a bit difficult. After determining the location, I removed the adhesive backing and attached the mirror to the glasses. Then I rode my road bike 40 miles to try it out. The journey included steep climbs and descents, narrow, winding dual carriageways and city streets. Because the scope's cone is very narrow, this is not easy or quick to do. In addition, the narrow cone of vision allows for a very limited view of the road behind you. If you have thick hair and I don't, chances are you won't see anything in the mirror but your own hair. After many adjustments I could only see about 50% of the road in the mirror, the rest was helmet straps and shoulder. head.Safety ConsiderationsI have serious concerns about the safety of using this product for anything other than regular low speed trail cycling.1. Scope resolution is too close to see detail beyond 50 yards. I heard the cars before I could see them (how close to the curb, what lane they were in, whether their rearview mirrors were sticking out, etc.).2. The narrow cone of the visor forces you to move your head for a few seconds and try to focus the mirror. You don't look ahead, which is a dangerous scenario when driving at higher speeds. I almost hit a couple of potholes/debris from not being focused forward. 3. The need to turn your head to the left and your eyes to the left forces you to steer your bike to the left in traffic. Experienced drivers know you're going wherever you look. As I tried to make amends, I was blown to the right side of the road. Both situations are extremely dangerous.4. My trip was early in the morning and I struggled with the sun shining behind the mirror and into my eyes. It was very uncomfortable and distracting. Because of this, I took off my glasses for the 4 mile west section. Trying to focus in the mirror after a while was very uncomfortable and resulted in eye strain and headaches.6. I would never rely solely on a mirror to control traffic when navigating around a roadside hazard or changing lanes. Do it if you're lucky. Conclusion: Mirror doesn't work very well and creates some unsafe scenarios. It is safer and more effective to traditionally tilt your head to the left and look backwards. This allows you to evaluate the traffic behind you quickly and reliably. If you are riding on narrow streets where you have to constantly look back for fear of being hit, you should still not ride a cyclist on that street. I would never use a mirror to look behind me at speeds over 10 mph. I found this very dangerous on fast descents (40+ mph) due to the distance traveled while trying to look in the mirror. Performance issues are what they are but due to security issues I will no longer use mirror and will never recommend it.
