I only need that for when navigating with the 800, so I can swap out those lens when not needed.
BTW, my race GPS is a Garmin 500 and never use that for navigating (in no-map mode). No reading glasses needed either
I have used Optx brand stick on lenses with some of my regular glass sunglasses but have had less luck when using them on wrap arounds. The curve of the wrap around type lens did not seem to work as well.
