The Igniter is a compact goggle with photochromic lenses so they can be used in all lighting conditions. The closed cell foam helps to create a wind free environment to eliminate eye tearing. The lenses are photochromic starting with a light tint (85% transmission rate) and transform to a medium gray (25% transmission rate) in bright UV light. The polycarbonate lenses are shatter resistant and come with an anti-fog coating. The Igniter also comes with a microfiber pouch for easy transport. *Please note that while these glasses would presumably pass ANSI Z87.1-2010 standards, they are NOT certified, and are therefore not endorsed as safety eyewear by Safety Glasses USA.
