Kobayashi Eyebon W Vitamin Premium is a Japanese medicated eye wash solution with a distinctive pink color due to its vitamin B12 content. This preservative-free formula contains maximum allowable concentrations of three vitamins (B6, B12, and E) plus amino acids. The solution is specifically designed for contact lens users to wash away dirt, dust, and protein buildup after removing lenses. It helps relieve eye discomfort, fatigue, and irritation while promoting eye health through its anti-inflammatory, antihistamine, and corneal protective ingredients. The 500ml bottle comes with a specially designed upward-facing eye cup for thorough eye cleansing.
