I have been using ocushield in all my devices, Like a lot of people I spent significant amount of time on my phone , iPad etc I remember in the past also that my eyes will cry once I have been on my devices for a long time Which also made it impossible to continue working unless I could have a few hours rest. For me at least once I have installed or concealed that inconvenience has disappeared. Without being a scientist I realise the benefit of those screens and I’m very grateful that there is a product to protect our eyes. I’m also excited for the new products coming up for the benefit of the eyes Thank you guys and keep up the great work
