These are SHATTERPROOF photochromic lenses that react to light. They're yellow indoors & at night but darken like sunglasses in sunlight. So you only need one pair of glasses for all conditions.
They're easy to slide in and out of a fastened helmet AND their ability to reduce wind turbulence is amazing. Better specification than some glasses costing many times more than these.
The yellow lenses react with the brain to create what can be best described as 'instant sunshine'. They also increase your depth & 3D perception of your environment, which is why many professional marksmen & engineers swear by them!
However they work, we guarantee you'll be amazed at just how they'll make those dull days a more pleasurable ride!!
Many users also find that these reduce night time glare from street lamps and headlights and this style of glasses are sometimes referred to as Night Vision Glasses.
Footnote: The lenses darken when they are exposed to UV400 light - most modern cars have a UV400 filter built into them - they will NOT darken if you use them in your car or behind a clear helmet visor with a UV filter
