Designed to fit the tightest helmets.
Simply take the padded insert into your local optician along with your prescription...the completed insert then clips neatly behind the lenses frame and you've got your correct vision.
The lenses are SHATTERPROOF photochromic items 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. Includes interchangeable goggles strap & hard case.
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
