ROHTO Vita 40α is a Japanese eye drop solution containing four essential nutrients: Vitamin E, Vitamin B6, sodium chondroitin sulfate, and potassium L-aspartate. This 12ml yellow-tinted formula provides a mild cooling sensation while effectively treating tired, red, and dry eyes. It helps reduce irritation, combat eye fatigue, and prevent blurred vision, particularly beneficial for those spending long hours on digital devices. The drops can be used 5-6 times daily with 1-3 drops per application. While safe for hard contact lenses, it should not be used with soft contact lenses due to potential tinting issues.
