Simpson helmet shields are offered in clear as well as stylish and functional tints. When ordering a shield for your racing or motorcycle helmet, keep these considerations in mind: Clear shields are generally used for night racing or very low light conditions Amber shields provide a minimal amount of tinting that's ideally suited to overcast weather Yellow shields are often used in dawn or dusk driving, as they tend to accentuate track features Tinted shields can help to eliminate glare during daytime driving High definition blue was first used by desert racers in dusty condition, but similarly to the amber shields it helps enhance contrast in cloudy conditions Some people find that mirrored shields block even more sunlight than tinted shields and Iridium shields provide the most protection from both sunlight and glare
