I couldn’t believe the convenience and ease to order Covisn color blind contacts online. I was able to order my contacts online at a time that was convenient for me and they were delivered directly to my home. Being a busy mom of two, every second counts and I’m so glad that I could save on time and money with this service. The contacts have been amazing in helping with my color blindness. I’m so grateful! It's been about a month since I got my first pair of colorblind contacts, and I've just ordered my second pair. They're just incredible. I'm red-green colorblind, and it's really hard to tell apart some colors, even close ones. I had never seen a bright orange before, or a bright yellow. The yellow car was a little bit harder to identify (it has a slight tinge of green), but the orange was easy as could be. I was really happy with covisn contact lenses! Covisn color blind contacts are exactly what I was looking for. The vision test is just a way to double check that the contacts are correct and that there’s no mistake with your prescription. It does not affect anything. Once you get your contacts, you will see that it’s as simple as putting in any other contact, and you will be surprised to see such vivid colorful world through them.

We lookied at 2 images for deuteranomoly he said this picture in this picture look the same to me. I was heartbroken at what he saw was the same because the pictures were completely different to me. I realized that my child had no idea what red look like and no idea what green looked like. His green looked like dead leaves to me and his brightest red looked brown. my husband and I decided to order the classes for him the next day. We gave them to him at a family party with balloons and all kinds of colored items and he was truly amazed. There was not a dry eye around. His initial reaction was total shock but as his brain adjusted, the colors got more and more vivid for him . I don't stop and write reviews very often but if you have red green colorblindness, these contacts really can help you enjoy the world. I wish my father could've had the chance to see the world through these contacts, he would have appreciated it!
