My father is a severe deutan color blind (red green color blind). We are taking a trip to Colorado to see the Aspens changing and thought these were worth trying and not a huge investment. He put them on and kept looking back and forth saying “wow†and then immediately asked to walk outside. He saw RED for the first time in his 71 years of life. He thought he knew what red was but had no idea until he put these glasses on. Even the sky was bluer. When we came home he excitedly walked inside proclaiming “our house is red! You never told me we lived in a red house! I thought the brick was brown!†HAPPY TEARS all around for this family!! These aren’t perfect, but fit well on to his trifocal prescription glasses and were well worth every penny to know if they even work before investing in a prescription pair. HIGHLY RECOMMEND!!!!

I knew i had erred when the first thing i saw was a piece of paper that read" if you are unhappy with this product, dont return it to amazon". They are obviously attempting an end around on customer rating. I took the test that is on their website . I could only see 1 of the test panels. WITH the glasses on, i was able to see 2. That doesnt seem like a significant improvement. they also give everything what i can only assume is an orange tint. Bottom line, dont waste your money.

My son has used these for driving for 2 years. They work well for him in detecting red lights and brake lights. However, he has had 2 pairs break. The price was good when I bought them, but not when I have to keep replacing them. I guess you get what you pay for.

I took the color blind test before ordering, and the results showed me being a strong Deutan. After putting on the glasses and taking the test again, it showed me being a mild Deutan. I wouldn't expect a miracle cure from these, but they did help. Everything looks a little more red or pink. I say that as a color blind peson, so go figure. I've only worn them for a day, so maybe things will improve. For now, I am not jumping up and clicking my heels saying, "These things are amazing." I am saying, "Looks a little more red. It looks a little different. I really can't tell if they are doing all that much." I think I am being generous giving four stars. The overall average of three and a half stars on here is probably a good reading of the effectiveness of the product.After having worn them on the water, I will say green navigational markers are darker, and red markers are lighter and brighter. Both are easier to see. That's a real plus for a boater.Almost a year later.After using the clip ons, I decided to get prescrition Enchromas. These are much better than the clip ons. While still not a complete cure (I went from being a strong Deutan to a mild Deutan on both the prescrition and clip-ons.) the prescription lenses are really terrific. I know here I am reviewing the clip-ons, but if you have a benefit from the clip-ons, your benefit from the actual prescritption glasses will be better - really a different experience. I love these things. And customer service at Enchroma is fantastic.

I bought these as a clip-on alternative to Enchroma glasses and I'm not disappointed! Previously, I had a hard time telling the difference between green and yellow lights on networking devices and now I can totally tell there's a difference with these glasses. Wish they were around decades ago.

I was very disappointed in the glasses. They made everything an amber color including the sky. I have seen the video of people crying when they saw the correction. I cried because they didn’t work for me. Bummer!

So first off you definitely want to take the quick quiz to make sure you order the correct ones. My husband has severe color blindness and these show him a whole new world!!!! Now he did go to the eye doctor and showed her his clip. She said ppl with color blindness shouldn’t wear these all the time. It confuses the brain bc your used to seeing one way and now you have these new colors which are much brighter now and see other colors a little different. Understandable. These are very nice quality and we don’t regret them one bit. She didn’t say not to wear them, just not all the time. We ordered the clip versus glasses because then he can use them with any prescription glasses. He is a hunter so he is looking forward to deer season so he can see the trail. He’s never been able to see a blood trail before and had to rely on other things like ruffled leaves etc. I highly recommend them, he highly recommends them, just make sure you talk to YOUR eye doctor about how often YOU should wear them. And ENJOY!!!!
