- By definition when you lower the blue light the screen colors will change a bit and the contrast will decrease
- Too much contrast between the colors is the main reason we feel eye pain in front of the electronic devices
- Too much contrast is not normal, when we read a book it adapts to the room lighting and the contrast is not huge
- You also know that the color of the pages in a book is not clean white but gray instead
- This also helps us read without feeling eye pain
- However, when you decrease the blue light you may notice that the letters are harder to read
- Not all people feel like this, generally the younger you are the less you will feel the effects of contrast and saturation
The goal of this page is to help you tweak the contrast and saturation while you lower the blue light emitted from the device
Possible Solutions
- They work only on Windows
- On macOS, there is no Saturation and Screen effects pages
Using MAX Saturation
- One possible solution to lower the blue light and make the letters more visible is to increase the Saturation
- This works only on Windows
- On macOS and Linux you can just increase the value of the Blue light to increase the contrast
To do this
- Open Iris
- Go to Advanced settings
- Scroll to Saturation and open the section
- Enable the use of custom saturation by switching the Saturation checkbox to ON
- Move the saturation slider to the biggest possible value
- This may make the text more visible while the Blue light is still lowered 🙂
The results of MAX Saturation
- This is how texts look WITHOUT the use of MAX Saturation
- This is how texts look WITH the use of MAX Saturation
It’s a small difference but maybe it will help 🙂
Using MAX Brightness
- Aside from that decreasing the Blue light decreases contrast
- Decreasing the Brightness will also decrease the contrast
- Thus another way to increase the visibility of the text is to actually increase the Brightness and decrease the Blue light more to get a similar luminance
To do this
- Open Iris
- Go to Advanced settings
- Scroll to Brightness and open the section
- From here you can increase the Brightness to the maximum and then lower the Blue light more
Using Daltonism color effects
- Same as the other solutions you can try to combine Blue light reduction with the Daltonism color effects
To do this
- Open Iris
- Go to Advanced settings
- Scroll to Screen effects and open the section
- From here you can try the different Daltonism effects
