I am sorry to hear that you have lost vision in your right eye. I have went most of my life with being blind in my left eye. It is a pain sometimes but you can make it and ride a bike again. My state restricts me that I can only drive vehicles with mirrors, but what car or bike doesn't have mirrors anymore. The big thing I have to stay conscious of is depth perception. I always allow plenty of room between me and the car in front of me, and when pulling into traffic when in doubt I wait. Again I am sorry but when the shock wears of remember you can still lead a very normal life. I would say protect the good eye you have left. I wear eye protection when riding, mowing, shooting, or anything that could cause damage to my good eye.
