I want to say thank you for an amazing product. I own my own Business at 23 and I work 7 days a week 10 hours a day with constant stress on my eyes. I also play on a team for Call of Duty Modern Warfare 2 for xbox and I am on for at least 3-6 hours a day. So I have a lot of headaches and stress on my eyes everyday. NOT anymore, I have already felt a difference in the first two days and I never thought that it would be this dramatic of a change. I have also told my team members and I will be ordering a pair for each member on my team. They have helped so much and I appreciate everything Gunnar has done for me. THANK YOU.
