Yamamoto Kogaku Protective Goggles with Back Made in JIS UV Protection YG-6000BB Easy-to-Attach Buckle, Scratch-Resistant, Anti-Fog, Japan, Standard,

The integrated wide spherical lens provides a wide field of view, both up and down and to the left and right. The PET-AF lens is hard-coated on both sides and has an anti-fog coating, making it scratch-resistant even under heavy use and ensuring a comfortable field of view. It blocks over 99.9% of harmful UV rays (up to 380nm). The "Scratch Guard" effectively protects the center of the lens from scratches. The integrated molding of the main frame and cushion provides high impact resistance, and the parts that come into contact with the skin are made of soft elastomer material. Easy to put on with a back buckle. Lens replacement is a breeze: simply turn the locking rubbers on both sides to unlock the lens, then lift up the frame.
