Developer's Comment (Hideyasu Sasaki, General Manager, Healthcare Promotion Department, Pharmaceutical Division)

Summer is a season when bacteria that cause conjunctivitis and styes tend to proliferate due to rising temperatures and humidity. Furthermore, with increased opportunities to visit swimming pools during the summer, the risk of viral infections also rises. When immunity is lowered due to summer fatigue, eye problems are more likely to occur. This product is a preservative-free antibacterial eye drop, carefully selected with only the necessary ingredients, prioritizing gentleness for weakened eyes. Please use it as an "emergency stock" item for sudden eye troubles during the summer, for your entire family.

※2 Compared to the same period from August 2024 to July 2025.
