Review on 👓 Ultimate Unisex Blue Light Blocking Glasses for Eye Strain - Stay Focused and Comfortable with Gaming and Computer Glasses (3pc-Leopard-Black-White) by Walter Day

If you need a colored mattress, skip this and buy a pair of Crizal Prevencia or Bluetech lenses. Regardless of the frame, the lenses are yellow. Applying filters to images during editing conveniently masks this fact. Some might not notice it with glasses (everyone's eye is different), but you can see how tinted they are on a piece of printer paper. There are two types of blue filter blocks. Chemicals that block blue light, leaving the lenses optically clear (like my Rx goggles), as well as the physical blocking of blue light that occurs when you add a yellow filter (like these Revain goggles). The yellow hue shifts the blue toward the green spectrum, but it also changes how you see all the other colors!
