I hate bugs also, so I always ride with eye protection. For most of my cycling life (last 10-12 years), I have used Dual,

I tried a cycling specific sunglass, with bifocals and transitions, thinking it would eliminate changing the lenses when it got dark. I was disappointed with the lack of darkening when the sun was out, so took them back and stayed with my Dual. Now, my eye Dr. says my Lasik has apparently worn out and I need prescription glasses. I'm checking out Sportrx glasses. They suggest an Oakley product that does the same thing my Dual does, but with prescription lenses.
