● Do not store with sharp objects.
● Do not use for sports or strenuous exercise.
● Do not use for long periods of time.
● If you feel any abnormality while using this product, please refrain from using it.
● If the lens is dirty, it may cause fogging, so please clean it.
● Avoid using color 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 may reduce visibility and be dangerous.
