Other Ways to Reduce the Effect of Blue Light

Apart from aforementioned ways, there are some ways that further reduce the effect of harmful blue light to the eyes.

Those who do color-critical tasks, we recommend wearing a blue-light cut glasses, because enabling the low blue light feature increases the color temperature of the screen.

It will affect your quality of work since you will not be able to achieve required color accuracy.

Always keep the room softly-lit to make it comfortable for your eyes to stare at the screen for prolonged hours.

If you experience eye-strain or headache even after implementing these ways, take small breaks and stare at a far distance while doing work.

This will relax your eyes and make you feel comfortable. Also, use artificial tears to keep your eyes wet and lubricated.

Small monitors can also make your eyes-strain, so we recommend using a large monitor for efficient reading and save your eyes from hurting.
