ROHTO Cool 40α is a Japanese eye drop solution that delivers four essential nutrients to combat eye fatigue and redness. This blue-packaged variant features a powerful cooling sensation and contains key ingredients: Vitamin E for blood circulation, Vitamin B6 for cell metabolism, sodium chondroitin sulfate for corneal protection, and potassium L-aspartate for oxygen delivery. With a 12ml capacity, it's particularly effective for people who experience digital eye strain from prolonged computer use, drivers on long journeys, and those exposed to environmental irritants. The recommended dosage is 2-3 drops per application, up to 5-6 times daily.
