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.
Exercises for the eyes
(1) Keep the body and the
head upright. Move the
eyes up to look at the
ceiling, then turn down to
look at the floor.
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.
Flicker-Free
The CDE30 series uses DC-adjustable backlighting, which does not produce a visible
or invisible flicker within the 0~3000 Hz range and therefore can reduce eye fatigue.
(2) Move the eyes le and
right slowly to look at
objects on the two sides.
