After wearing my outdoor Enchroma Ellis glasses for 3 1/2 years and being extremely happy with them, it was time to order another pair and also order a pair of the indoor glasses. I'm a strong protan and severely colorblind and the indoor glasses work as well for me as the outdoor glasses and I simply couldn't be happier! The lens quality is excellent and my prescription was created flawlessly and the clarity and colors I see are truly amazing!

I really love the glasses. The new colors i am experiencing are amazing!

I can see the difference between orange and green also yellow and red improved, I would not compare it cx3 sp, but I can't use the cx3 sp indoor. cx3 sp give me better result outdoor

I decided to try the Grant Cx1 Indoor glasses based on my experience with the enchroma sunglasses. The indoor glasses' color enhancement is more subtle. In low indoor light their is a noticeable tint. Neither is distracting after a day or two. Like the sunglasses, the indoor lenses open up an entire world of previously under-appreciated color. I wouldn't be without them for browsing the web, watching television or fly-tying. Enchroma applied my tri-focal prescription skillfully. My fields of vision are even clearer than with my normal lenses.

I got the Grant Cx1 Indoor glasses for my boyfriend as an early Christmas gift (I got them in fall so he could see all the pretty colors). He has Protan color blindness and has difficulty distinguishing red from brown, blue from purple and whatnot. I was so excited when they came in the mail, I surprised him with them and they sent these nice balloons of all the colors of the rainbow. Before he put them on I asked him which colors were which and the blue and purple were essentially the same color, along with brown and green. He put the glasses on and boy I wish I would’ve filmed it. Made him cry. Amazing product, really works. Worth the money.
