So I got a new pair of prescription sunglasses this year and when I was getting everything for it I decided to get their new Prizm technology added to it. The first time I put them on outside it was like seeing a 4k HDR T.V. for the first time. It does something to the colors and makes everything so colorful. The greens are more vivid. Everything has a color intensity to it. But not overdone. It really is amazing technology. I almost hate taking them off.
