Blue Light Filter and Eye Health
The Blue Light Filter blocks high-energy blue light for a more comfortable viewing
experience.
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.
• The monitor also supports Flicker-Free, which reduces or eliminates screen
flicker, thus easing potential eye strain.
• Setting the filter value to 100 will provide the best performance of the blue light
filter, which meets TUV certification standards.
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.
