Prevent "Computer Vision Syndrome"
People will feel uncomfortable if using computer for a long
time. Ophthalmologist and optometrist call it as "Compu
ter Vision Syndrome (CVS)". Details onCVS are as follows:
1. Eye fatigue will be aggravated If not blinking for a
long time upon watching fluorescent screen.
This circumstance is often when reading lots of files, for
computer user does not blink or blink as less as possible
to avoid missing content. Blinking is critical for eyes
protection. It offers position change opportunity to
tense crystalline lens and iris muscle, so as to lubricate
eyes and prevent eyes from generating itching and
burning sensations and other symptoms.
2. The abnormal reaction "McCullough effect" will be
generated after seeing green words in black
fluorescent screen while working before fluorescent
screen.
Though harmless to body, this symptom can last
for several days. White colored space or image turns to
pink.
3. Knowledge regarding operator wearing bifocal
glasses.
For this kind of people, optimum location of all objects
should be on or below chest, with 12-18 inch distance.
If the height of fluorescent screen is not appropriate or
the distance is too near, computer user will
uncomfortably bend or have his or her head keeping a
quite unnatural angle, which can cause dizziness, neck
sore, shoulder sour or general malaise. According to
expert, computer operating is a kind of work required
for straining eyes, and it can reduce secretion of
lubricant and enzyme in eyes. General speaking, there
will be eye dryness and fatigue, ghosting, blurred vision,
head and neck soar and other symptoms if times of
blinking is less than 5 and interval is relatively long.
