I researched a product that will help me in my eyes less tired front of the computer (I spend 10 to 15 hours a day) I did some testing with ophthalmologist .. but as I have nothing to give me 10/10 I have heard of this brand so I wanted to try The bezel in it even, nothing to say, very correct When placed, the color is slightly modified and especially light "zoom" noted By cons during my test three days, I felt that I had more eyes hurt so I removed them and tried again qq days later, the same I will do another test here qq days I am afraid that the "zoom" that makes me worse without the glasses
