Our Optic Renew Eye Treatment Drops contains vitamin B6, glucan and potassium aspartate. It can effectively protect the eyes, replenish the substances and moisture needed by the eyes, improve eye comfort, relieve eye redness, fatigue and other problems, and bring health and new luster to your eyes. The way to use it is simple: clean your hands before use, tilt your head back or lie flat on your back, pull down your lower eyelids to separate them from your eyeballs, drop the product into your eyes, close your eyes for at least five minutes, and use a tissue or towel to wipe away any droplets of water and tears that come out of your eyes. It can help repair damaged optic nerves, restore your vision, and bring a new light to your eye health.
