Computer Vision Syndrome And Ayurvedic Treatment
Computer Vision Syndrome And Ayurvedic
Treatment
The most common symptoms associated with Computer
Vision Syndrome (CVS) are
- eyestrain
- headaches
- blurred vision
- dry eyes
- neck and shoulder pain
These symptoms may be caused by:
- poor lighting
- glare on the computer screen
- improper viewing distances
- poor seating posture
- uncorrected vision problems
- a combination of these factors
The extent to which individuals
experience visual symptoms often depends on the level of their visual abilities
and the amount of time spent looking at the computer screen.
Many of the visual symptoms
experienced by computer users are only temporary and will decline after
stopping computer work. However, some individuals may experience continued
reduced visual abilities, such as blurred distance vision, even after stopping
work at a computer. If nothing is done to address the cause of the problem, the
symptoms will continue to recur and perhaps worsen with future computer use.
Prevention or reduction of the
vision problems associated with Computer Vision Syndrome involves taking steps
to control lighting and glare on the computer screen, establishing proper
working distances and posture for computer viewing, and assuring that even
minor vision problems are properly corrected.
Viewing a computer screen often
makes the eyes work harder. As a result, the unique characteristics and high
visual demands of computer viewing make many individuals susceptible to the
development of vision-related symptoms.
Uncorrected vision problems can increase the
severity of Computer Vision Syndrome symptoms.
Viewing a computer screen is
different than reading a printed page. Often the letters on the computer screen
are not as precise or sharply defined, the level of contrast of the letters to
the background is reduced, and the presence of glare and reflections on the
screen may make viewing difficult.
Viewing distances and angles used
for computer work are also often different from those commonly used for other
reading or writing tasks. As a result, the eye focusing and eye movement
requirements for computer viewing can place additional demands on the visual
system.
In addition, the presence of even
minor vision problems can often significantly affect comfort and performance at
a computer. Uncorrected or under corrected vision problems can be major
contributing factors to computer-related eyestrain.
Even people who have an eyeglass
or contact lens prescription may find it's not suitable for the specific
viewing distances of their computer screen. Some people tilt their heads at odd
angles because their glasses aren't designed for looking at a computer. Or they
bend toward the screen in order to see it clearly. Their postures can result in
muscle spasms or pain in the neck, shoulder or back.
In most cases, symptoms of CVS
occur because the visual demands of the task exceed the visual abilities of the
individual to comfortably perform them. At greatest risk for developing CVS are
those persons who spend two or more continuous hours at a computer every day.
Solutions to computer-related
vision problems are varied. However, CVS can usually be alleviated by obtaining
regular eye care and making changes in how you view the computer screen.
Eye Care
In some cases, individuals who do not require the
use of eyeglasses for other daily activities may benefit from glasses
prescribed specifically for computer use. In addition, persons already wearing
glasses may find their current prescription does not provide optimal vision for
viewing a computer.
- Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Lenses prescribed to meet the unique visual demands of computer viewing may be needed. Special lens designs, lens powers or lens tints or coatings may help to maximize visual abilities and comfort.
- Some computer users experience problems with eye focusing or eye coordination that can't be adequately corrected with eyeglasses or contact lenses. A program of vision therapy may be needed to treat these specific problems. Vision therapy, also called visual training, is a structured program of visual activities prescribed to improve visual abilities. It trains the eyes and brain to work together more effectively. These eye exercises help remediate deficiencies in eye movement, eye focusing and eye teaming and reinforce the eye-brain connection. Treatment may include office-based as well as home training procedures.
Many of the time some health problems may make the situation bad. So systemic treatment of other associated factor also very important.

Viewing the Computer
Some important factors in preventing or reducing
the symptoms of CVS have to do with the computer and how it is used. This
includes lighting conditions, chair comfort, location of reference materials,
position of the monitor, and the use of rest breaks.
- Location of computer screen - Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20 to 28 inches from the eyes.
- Reference materials - These materials should be located above the keyboard and below the monitor. If this is not possible, a document holder can be used beside the monitor. The goal is to position the documents so you do not need to move your head to look from the document to the screen.
- Lighting - Position the computer screen to avoid glare, particularly from overhead lighting or windows. Use blinds or drapes on windows and replace the light bulbs in desk lamps with bulbs of lower wattage.
- Anti-glare screens - If there is no way to minimize glare from light sources, consider using a screen glare filter. These filters decrease the amount of light reflected from the screen.
- Seating position - Chairs should be comfortably padded and conform to the body. Chair height should be adjusted so your feet rest flat on the floor. If your chair has arms, they should be adjusted to provide arm support while you are typing. Your wrists shouldn't rest on the keyboard when typing.
- Rest breaks - To prevent eyestrain, try to rest your eyes when using the computer for long periods. Rest your eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow your eyes a chance to refocus.
- Blinking - To minimize your chances of developing dry eye when using a computer, make an effort to blink frequently. Blinking keeps the front surface of your eye moist.
