I'm very happy with my purchase. They work great and as advertised. I've shared my experience with friends and family so they can enjoy them too

My son was so happy with his color blind glasses. The price is so cheap compared to anywhere else and the shipping was really fast.

I tried them myself and I was surprised how well they work. The contacts are comfortable and lightweight, so you can wear them all day long!

Love them! They work great!

It's so cool that I can see the beautiful world in vivid colors

I was so glad I found these contacts because they made me pass my colorblind test

I was looking for a color blindness cure and I found this contact lenses that really works!

The product works. I have tried it and can tell you that it would work for you too.

I'm a red green colorblind and I used it, it works!

I've just started using these glasses and I've definitely noticed an improvement.

I have red green colorblind,the contacts help me pass the ishihara test.thank you!

Firstly, I urgently needed the item and paid the fast shipment charge too. But, surprisingly, received it on a day when even the normal delivery will be considered late. Later, although on my request, you refunded my fast shipment charge of 90 USD, but that had to be negotiated through call center. thanks to the Call center girl for her nice gesture of ensuring the refund. One more thing that I would like to mention that, please make sure to prevent corrupt practice of Dhaka UPS staff at the Airport. They were found to have a link up with the corrupt custom clearance system and as such no client can get away of this system and we are all victim. UPS as an international organization, it is strongly recommended to kick out all corrupt local staffs, as they might bring disaster for UPS at any time by spoiling image.

Covisn was just what I was looking for I probably spent three or four years trying to find some contacts that would correct my red green deficiency. couldn’t find them anywhere and i ran across covisn on the web. When I contacted covisn someone got right back to me to answer any concerns I received them in a couple weeks I went to my eye doctor so she could help me put them in and she gave me a test infact she took the email address for covisn because she knows people that want to get the same thing. all I can say is thank you civisn it’s something I’ve been hunting down and you guys have really good support thanks couldn’t believe it I could read all the numbers on the Ishihara test

The website has a lot of great products and information to help with color blindness. The support team helped a lot when my package got stuck in customs. They actually sent me another set free of charge!! That's amazing service you can count on!!

I just waster 100€, becau it was not working…

It has been more than 2 months and I haven't received my lenses. I want my refund
