● If you feel any abnormality while using this product, please refrain from using it.
● If the lenses are dirty, they may fog up, so please clean them.
● Avoid using colored lenses (concentration 25% or more, visible light transmittance 75% or less) or photochromic lenses that change color when exposed to UV light in dark places (at night, dusk, cloudy days, inside tunnels, etc.). Insufficient light can reduce visibility and be dangerous.
