So to clarify this a little.
My right eye is kinda screwed. I see fog on it and I depend basically on my left eye. That's why I also find interesting idea about rear view camera.
So back to the topic. Tested today those little mirror and I was quite surprised how they work. I can see my knees when pedaling but I also see a lot of action going on on my left side and right side.
But on bad side I can't see right behind me what is happening. First impression is kinda weird to need to look down to check what is happening behind you on your left or right side, but I could get used to it.
For the ones suggestion turning your head, try turning your head on right side with right eye closed and you will be on the same spot like I am
Schulze suggested some idea, but to be honest I am middle age man and I am afraid I would look like alien with this kinda solution. And I would like to get laid in the future... -.-
If I would wear solution like that in my country, I can guarantee I can sign up for monk in monastery. So no thank you, I would like to have some fun in the future
Either way I am very gratefull for all of your ideas, even for yours Schulze.
To bad you don't like to post pictures, so from time to time I need to use my imagination what you guys are using. To be honest I wouldn't mind alien looking glasses on chick like Schulze has in his avatar...
