These glasses are awesome. Truly. I stare at multiple large computer screens, tablet screens and phone screens all day and towards the end of the day my eyes are completely worn out. They’re dry, tired, hurting, and have dark rings around them from excessive strain throughout the day. NOT ANYMORE! It’s incredible how much these glasses help with these issues. I won’t hardly look at any type of digital screen without wearing the glasses now. Quality is obviously a high priority to the manufacturer, not only in the glasses themselves but the packaging and storage case they come in as well. Without a doubt one of the best Amazon purchases I’ve ever made, and I’ve literally made hundreds of them.
