When I received the drops in the mail I was very skeptical. I've used Clear Eyes and Visine and keep it in my makeup bag to clear eyes before a special occasion or after a long night. Those brands work okay but sometime burn my eyes so they end up looking more red later after its worn off. I dropped the Collyere Bleu drops in my eyes and they didn't burn at all. After two drops and five minutes the whites of my eyes were clear and my blue eyes sparkled. It lasted all day long. I plan to use it on my models for photo shoots prior to the makeup application.
I'm impressed!
