The product did not relieve my eyestrain. It's not good as they said for the price paid. Customer service is terrible. I use my computer 8 hours a day. I want to find something that can relieve eye pain because I have been using the computer for a long time. I thought this might work. But it did not work. I still feel pain in my eyes from this computer screen. For the price you pay, you can find other products that are much cheaper and work better. If you don't mind wearing glasses, use them. (The glasses have more functions and are more professional than this computer screen) http://www.amazon.com/gp/product/B00BQ7KBV4?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s00 Or you can buy these much cheaper and do the same job (anti-glare for only $10). http://www.amazon.com/COOSKIN%C2%AE-15-6-Screen-Protector-Display/dp/B00D84GA40/ref=sr_1_2?s=pc&ie=UTF8&qid=1457278727&sr=1-2&keywords=computer+screen+ ProtectorService Customers are terrible. Make sure you measure the screen protector in the size they send you. I bought a protective film for a 17' screen. But they sent me a 15 inch screen protector. They punished me for what they did wrong. Very disappointed.
