Review: Really helping with eyestrain. - After decades of screen time, my eyes are very sensitive. The difference seemed subtle at first. However, after hours on the screen my eyes did not feel fatigued or strained. It felt similar to wearing polarizing sunglasses. Buying again for other devices. Great product, easy to use.
Review: Fantastic product - Works great! I can see perfectly fine and have not been having a headache when looking at my screen for so long. True to size. I just got them a couple of weeks ago so it will be a matter of waiting to see how long they'd last for but seem to be great material.
