One of my closest friend is a strong protan which he sees greens, yellows, oranges, reds, and browns as appear similar colors, especially in low light. Red and black might be hard to tell apart for him. I am planning to buy one of the Enchroma Glasses which is a type of glasses that colorblind people use to see the colors like we see them. He will see the colors for THE FIRST TIME in his life.
If you are wondering how he sees the colors. Here is a photo for it : https://i.pinimg.com/originals/43/b6/4f/43b64fa979185c34bf3117643a02c0e1.jpg (The left one in the down)
So I want to buy and Outdoor Glass. Here is the link : https://enchroma.com/collections/outdoor/products/derby?variant=13725742727231
The glasses will be with a special lens, since he is a strong protan. You can see it at the left of the page as "Cx3 Sun SP".
So I hope you want to be a part of this. Thank you!
