This is my favorite pair of blue light blocking glasses to date. They are very well made and almost feel like prescription frames. The style factor is outrageous. I got the pink and black gradient frames, and it it's absolutely fetching! I was worried they would look tacky on me, but they look great.The blue light blocking is average - it doesn't really turn anything green, but it does take the bite out of it by making it a tad more yellowish, much like a night light app does but more effective since it takes care of indoor lighting as well and not just the screen. For me, they effectively keep me from getting migraines or blurry vision/sore eyes, and I have grown to prefer them to my prescription glasses for this... fortunately I am near sighted and only really need glasses for reading at a distance. I am light sensitive & have astigmatism... for those things, these are great and have reduced symptoms. I appreciate that they don't screw with colors too much.If you're someone that wears this type of glasses all day/every day, or are thinking about starting, I'm pretty certain you'll love these. If you are looking for glasses that remove most or all blue light, you may be disappointed by these - look for glasses with yellow or orange lenses and you will find what you're looking for.
