What is a Protan?

Protans are people withย Protanomaly,ย a type of red-green color blindness where the red cones in the eye do not detect enough red light, but instead respond more to green light.

As a result, many colors such as green, yellow, orange, red, and brown may appear confusingly similar. People with color blindness often also confuse blue and purple, and see pink as a shade of gray or white.

When all red cones are missing the Protanomalyย condition is calledย Protanopia.

Protanopia

Protans with Protanopia (also called red-blind) are Dichromats.

In this case the long wavelength sensitive cones (red) are missing at all. A protanope can only distinguish 2 to 3 different hues, whereas somebody with normal vision sees 7 different hues.

Protanomaly

Protans with Protanomaly (red-weak) areย Anomalous Trichromats.

This can be everything between almost normal color vision and protanopia. The red sensitive cones are not missing in this case, but the peak of sensitivity is moved towards the green sensitive cones.

How Protans see the world?

To Protan the above images will look almost the same.

How to setup Vision for Protans?

From the Setup menu choose Protanopia.

The colors of the screen will now change. Screen colors are daltonized in real-time.

This is general preset for people with Protanomaly and you should now be able to distinguish more colors.

If you want more fine control you can buy Vision Pro. With the Pro version of Vision you can customize the Severity of your color vision deficiency and the Color adjustment applied to the screen.

The recommended Severity for Moderate Protansย is 75-100%.

Move the Color adjustment slider as you like. For best color discrimination use the most left or right position of the slider. Values in the center have really small color correction.

Happy using of your new computer full of colors ๐Ÿ™‚

    Wow. This is SO true for me.
    This ‘app’ seems to do so some great changes for my screen. Well done on developing this. Seems so easy

  2. “To Protan the above images will look almost the same.”
    That’s correct; almost the same…

    Running the tests multiple times, I got strong or complete protan status.
    Currently I am playing with settings Severity 100% with a 10-20% Color adjustment.

    Not sure exactly what it means ‘until all letters are visible’: in term of optimal contrast or merely visible? Strangely Color at 0% and Severity 100% seems a ‘nice view’ of A letters but eveything else also seems so ‘blue’. So weird, too. Now I need Iris for all that excessive blue?!! I don’t know…

    The issue is I am not sure how the ‘real world’ should look like … now… I need some references. I don’t know what makes sense. Really. But this is surely a WOW with Vision Pro!
    Thank you Daniel!

    1. Hi Carl,
      It means that you should adjust your settings so that you can comfortably see all the letters displayed above

      Iris is a program that removes blue light and flicker from your screen so you can sleep better and feel less eye strain from your computer ๐Ÿ™‚
      You can try it here:

      It will help your eyes to see better ๐Ÿ™‚
