These glasses are life changing. I cant begin to explain (I guess this counts as beginning) how much this has already changed my life. One example is that I have gotten these glasses during the dullest season of the year and I’m still see new colors in nature that I never knew existed! Thank you so much for this life changing opportunity. Oh and traffic lights aren’t a problem anymore for me. That’s the biggest game changer.



First time seeing green!

To be honest, I wasn't particularly excited when my wife ordered EnChroma glasses for me. I've always known that I was colorblind but never thought I was missing anything; after all, I do see colors, just not all the correct ones. My expectation was that they would be a subtle enhancement of what I already see. When we received them it was evening and I had ordered sun glasses because I figured that I would be more likely to wear them if there was a function beyond color correction. The lenses are tinted enough that in low light they are not as effective. We turned all of the lights on as bright as we could in the room and our kids and grandkids gathered to watch. I was mesmerized by how bright colors are! I was able to see purples and greens, but most surprising were the reds. I have always seen red but didn't realize how vibrant it can be! The Christmas decorations were out and the reds were distracting in their amplitude. Next day we went on a drive and I was amazed. I will be ordering a pair without tint so that I can wear them indoors. Thank you!

Life changing

These glasses were a gift for my husband. We were both worried about the possibility that they may not work; however, they greatly exceeded our expectations. I purchased them just in time for him to see the changing leaves and we are both so excited about our future colorful adventures together. I cannot thank you enough for making these glasses.
