Blue Light Filter and Eye Health

The Blue Light Filter blocks high-energy blue light for a more comfortable viewing experience.

Quick Access Blue Light Filter Setup

Enabling and disabling the Blue Light Filter can be done on the fly via the Quick Access Key.

NOTE: When enabling the Blue Light Filter (BLF) via the Quick Access Key, the BLF value will be 100 which is certified by TÜV. However, the BLF value will be 0 if the user chooses another function via the Quick Access Key.

While using and enjoying your monitor please keep the following in mind:

Viewing computer screens for extended periods of time may cause eye irritation and discomfort. To reduce these effects, it is recommended to take periodic breaks from viewing to allow the eyes to relax.
Users can customize the Blue Light Filter value through the Game Modes Menu.

The monitor also supports Flicker-Free, which reduces or eliminates screen flicker, thus easing potential eye strain.

Calculating Breaks

When viewing the monitor for extended periods, it is recommended to take periodic breaks from viewing. Short breaks of at least five (5) minutes are recommended after one (1) to two (2) hours of continuous viewing. Taking shorter, more frequent breaks are generally more beneficial than longer, less frequent breaks.

Looking at Distant Objects

While taking breaks, users can further reduce eye strain and dryness by focusing on objects that are further away from them.

Eye and Neck Exercises

Eye Exercises

Eye exercises can help minimize eye strain. Slowly roll your eyes to the left, right, up, and down. Repeat as many times as needed.

Neck Exercises

Neck exercises can also help minimize eye strain. Relax your arms and let them hang at your sides, bend forward slightly to stretch the neck, turn your head to the right and to the left. Repeat as many times as needed.

ViewScale
