Review on Swanwick: Classic Night Swannies - Premium Blue Light Blocking Glasses - Superior Blue Light Blocking for Gaming PC, Laptop, and Smartphone Glare - Black - Small - Sleep Support by Brian Sitton

These glasses fit great (for a 5ft woman I bought a smaller pair) which is great because they filter all the light and have no gaps. The fact that they fit so well ensures they perform exactly as they were designed. I am very satisfied with these light filter glasses. I applied them a few hours before bed and found that they really help. They're especially good when I use my Kindle to read or before bed on my mobile device.
