21st Century Lifestyle Demands

21ST CENTURY LIFESTYLE DEMANDS
MORE FROM OUR VISION THAN EVER BEFORE

Our visual system was not made for prolonged
periods of near point work like working on a computer.

  Our visual system was designed for distance work

It was made to hunt, fish, farm and locate danger.

 Many of us experience:

  • eyestrain
  • eye fatigue
  • headaches
  • blurred vision after using a computer for a short period of time

 THIS IS KNOWN AS COMPUTER VISION SYNDROME

 

COMPUTER VISION SYNDROME (C.V.S.) IS ONE OF THE FASTEST GROWING EYE HEALTH CONCERNS IN SOCIETY TODAY.

  Computers                                               and                                          hand held devices 

   have made their way

 into our everyday  lives.

Be it at work and/or at home, adults as well as children inadvisably push their eyes past the point of eyestrain. Excessive computer use and/or uninterrupted close work can induce eyestrain, headaches, and/or other visual difficulties, which can be effectively treated with Vision Therapy.

 Do you experience eyestrain, headaches or blurred vision after working at your computer?  You may have Computer Vision Syndrome (CVS).

WHAT IS COMPUTER VISION SYNDROME?

The National Institute for Occupational Safety and Health (NIOSH)  defines computer vision syndrome (CVS) as “eyestrain associated with prolonged computer use.”

 The American Optometric Association (AOA)  expands on this definition, calling CVS “eye and vision-related problems related to near work which are experienced during or related to computer use.”

 Symptoms of CVS fall into three categories:

  1. vision problems
  2. eye problems,
  3. general discomfort


Vision problems can include:

  • blurred vision (both near and far)
  • difficulty changing focus
  • double vision
  • glare
  •  flickering sensations
  • temporary changes in color perception.

Eye problems can include:

  • redness
  •  burning sensation
  • soreness
  •  stinging
  •  itchiness
  • dryness
  • excessive tearing
  • eye fatigue
  •  eyestrain
  • light sensitivity
  •  contact lens discomfort

General discomfort symptoms can include:

  • headaches
  • neck tension or pain
  • shoulder tension or pain
  •  back pain
  • pain in arms or wrists
  •  excessive fatigue
  • irritability
  • drowsiness 

HOW COMMON IS CVS?

The American Optometric Association estimates that 70% to 75% of all computer users experience CVS symptoms.

 Approximately 95 percent of the population keeps both eyes aligned on the object of regard, as shown in the Figure below.

Even though most people work hard at keeping their eyes aligned when viewing an object, many individuals have difficulty maintaining this ocular alignment. The symptoms associated with phorias can be:

  • eyestrain,
  • double vision,
  • headaches,
  • eye irritation, and
  • general fatigue.

If the eyes do not naturally line up, as is the case for most people, then a constant neuromuscular effort is required to avoid the above mentioned symptoms.

Vision is our most precious sense. Our    are in constant use every waking minute of every day.

The way we use our    can determine how well we work throughout our lifetime.

Over 80% of our learning is mediated through our 

indicating the important role our vision plays in our daily activities. Vision disturbance is a silent enemy that only appears after a long period of continued stress.

Today, millions of children are using computers every day, at school and at home, for education and recreation. Visual demands in school require the integration of a number of different vision skills:

  • visual acuity (sharpness of vision);
  •  visual fixation (eye aiming);
  • accommodation (focusing);
  •  binocular fusion (forming a single image);
  • convergence (turning of the eyes);
  • field of vision (side vision); and
  • form perception (recognizing shapes).

These systems can be stressed and overworked if not used efficiently. Computer viewing is complicating how children use their 

in school because these visual skills are not yet fully developed in children—making any near-point activities that much more difficult.

TROUBLE ON THE JOB?

Many adults have vision problems, eye problems, headaches, visual difficulty using computers or doing close work, both on the job and on their own time.  The cause may also be a vision problem that can be addressed by vision therapy why put up with computer eyestrain when you don’t have to?
