I would not recommend transitions. I have them on my glasses and I also have prescription sunglasses. Transitions need direct sunlight to be effective. If the visor on your helmet or a hat bill or rim is blocking the sun, your transitions will not have any affect. This sucks on a bright sunny day because everything around you is bright and your transitions do nothing to help (again when the sun is not hitting them directly). Also, the transitions have no affect while driving your car or truck regardless if the sun is hitting them directly because of the uv in your windshield.
