The optical inserts are cheaper because you only buy one prescription lens set and multiple (much cheaper) lenses for different applications. The problem (for me) with the insert is my lashes are really long and would brush up against the inner lens which smudged them constantly. I also had two sets of lenses I needed to keep clean. Right now I have two sets of riding glasses which are dark polarized and no tint for day and night riding, respectively.
