New and unused. Anti-fog gel developed by a medical eyeglass manufacturer. It's a non-splattering gel type that is less volatile and lasts longer. It can be used not only for SOLAIZ but also for anti-fogging your existing glasses. [How to use] Apply one drop (about 3mm in diameter) of gel to both sides of the lens, gently spread it with a tissue paper, let it dry for about 30 seconds, and then gently wipe it off. *The key is to let it dry for more than 30 seconds to ensure the anti-fog agent adheres firmly to the lens, and then wipe it clean at the end. *Wiping strongly or with a microfiber cloth will weaken the anti-fog effect. *If you apply too much gel, white streaks may remain on the lens surface. *Can also be used on coated lenses.
