Low Blue Light Filter and Eye Health
The Blue Light Filter blocks high-energy blue light for a more comfortable viewing
experience.
NOTE: To meet TÜV Rheinland low blue light certification, the Display Settings
must be:
• Mode: Standard (Brightness and Contrast are 50)
• Color Temperature: Filter
• Blue light Filter: 0
Calculating Breaks
When viewing screens for extended periods, it is recommended to take periodic
breaks from viewing. Short breaks of at least 10 minutes are recommended after
one (1) hour of continuous viewing.
Taking shorter, more frequent breaks are generally more beneficial than longer, less
frequent breaks.
Focus Fatigue (20-20-20 Rule)
To reduce the risk of eye fatigue by constantly looking at the screen, look away from
the screen at least every 20 minutes and gaze at a distant object (at least 20 feet
away) for at least 20 seconds.
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 for 10-15 seconds, then gaze at something
up close for 10-15 seconds. Repeat this up to 10 times. This exercise reduces the
risk of your eyes’ focusing ability to “lock up” after prolonged computer work.
