Computers are one of the most fascinating inventions of the 20th century. However, computer users confront new challenges at their workplace and school system. By working long hours using a computer monitor, a compilation of systemic and ocular symptoms can develop.
According to the United States Bureau of Labor Statistics, in the United States, computers are used by 100 million people at their jobs daily. Further, according to the National Center for Education Statistics, 95% of schools and 62% of all classrooms in the United States have had computers since 1999.
Definition
Visual and ophthalmic symptoms are common among computer users and have collectively been called computer vision syndrome (CVS). Ocular symptoms associated with this syndrome include decreased vision, burning, stinging, and photophobia.
Frequency
A large percentage of computer users have eye symptoms and, thus, seek eye examinations. According to Thompson, the prevalence of ocular symptoms in computer users, as part of CVS, is 25-93%.1
Studies done by Sheedy and coworkers suggest that 1 out of 6 patients requiring eye examinations have a computer-related eye problem.2 The cost of eye care examinations and glasses made for computer users is a nearly $2 billion industry, although these costs are certainly not all directly a result of CVS.
Comorbidities
Hales and coworkers showed that 22% of computer workers have musculoskeletal problems, such as neck problems, back problems, shoulder problems, and/or carpal tunnel syndrome.3

Etiology
The etiology of CVS is most commonly multifactorial. Various factors may lead computer users to this syndrome. These factors may be environmental, personal, or a combination of both.
Environmental factors
Computer users gaze at the computer monitor at a particular angle of gaze. A wide variety of angles exist in workstation and desk settings. Also, a large variety of light fixtures and illumination sources exist at the workplace.
Personal factors
Uncorrected refractive errors may contribute to CVS and fatigue with visual tasks. Computer users who are middle aged and older may have presbyopia. Presbyopia affects near and intermediate visual acuities, which are needed for the various working distances of computer users. Working for prolonged periods of time looking at the computer monitor is a risk factor that may also lead computer users to have eye symptoms. Further, patients with preexisting dry eyes may have exacerbated symptoms when using a computer.
Combined factors
Computer users who have presbyopia and dry eye (personal factors), who gaze at the monitor with an extended neck (environmental factor) may have symptoms associated with this syndrome.

Clinical
History
The patient's history should be obtained, including age, chief complaint, and onset of symptoms.
• In obtaining a history of present illness, the ocular symptoms should be evaluated. Patients with CVS complain of several symptoms, such as dryness, burning sensation, stinging, red eyes, blurred vision, tearing, and photophobia.
• Previous eyeglasses prescriptions, ocular medications, and lubricant therapy should also be evaluated.
• The review of systems may include such issues as xerostomia, thyroid disease, menopause, arthritis, carpal tunnel syndrome, Parkinson disease, and systemic medication use that may exacerbate dry eye symptoms (eg, anticholinergics, antihistamines, antidepressants, diuretics, cholesterol medications).
• The environmental factors, such as computer setup, seating, wrist position, monitor type (cathode ray tube vs plasma), desktop color, window proximity, and ceiling and desk illumination sources, should be evaluated.
Physical
Patients with CVS should undergo a comprehensive ophthalmic evaluation that includes the following:
• Best-corrected visual acuity for near, intermediate, and distance vision
• Manifest refraction at near, intermediate, and distance for refractive errors - Computer users may have refractive errors, including presbyopia.
• A slit lamp examination to evaluate tear meniscus and corneal staining
o Patients with this syndrome may have superficial punctate keratitis.
o The lens should be evaluated for cataract formation.
• Intraocular pressure should be evaluated.
• A fundus examination to evaluate the optic nerve, vessels, macula, and peripheral retina
• A cycloplegic refraction is of utmost importance because young computer users with this syndrome may have refractive errors, particularly latent hyperopia, that may lead to visual symptoms.
• A Schirmer test to evaluate for dry eye
The general physical features in patients with CVS include neck muscle spasms.
The general environmental evaluation in patients with CVS includes the following:
• Angle of gaze
o Previous studies suggest that the angle of gaze is the most important risk factor that leads computer users to develop CVS. For this reason, it is of utmost importance to estimate the angle of gaze needed to look at the computer's monitor. For the purpose of this discussion, the center of the monitor will be used as a reference point to measure distances both from the floor and from the lateral canthal area, as shown in Media file 1.
o To calculate the angle of gaze that a patient uses at the workstation, the ophthalmologist may measure or ask the patient to measure the following:
 The distance from the computer user's body to the center of the monitor (labeled as A)
 The distance from the floor to the center of the computer monitor (labeled as B)
 The distance from the floor to the lateral canthal area of the patient's eye (labeled as C)
o The absolute value of the difference between the distance from the floor to the center of the computer's monitor (labeled as B) and the distance from the floor to the lateral canthal region of the computer user's eye (labeled as C) is calculated and labeled as D. In other words, ([B - C]) equals (D).
o Using this information, the angle of gaze that a patient uses to look at the center of the monitor is calculated using the following formula:
Angle of gaze = tan-1 (D/A)
• Estimate room humidity.
• Evaluate room luminance.

Causes

Environmental factors, such as a large angle of gaze, low humidity, and excess room illumination, may exacerbate the symptoms associated with this syndrome in computer users.

Computer users open their interpalpebral fissures to look at their monitors, as opposed to office clerks who look downward at their desktops. Therefore, computer users have more eye surface exposure to environmental factors, which may lead to increased tear evaporation.
• When the monitor's center is positioned higher than the intercanthal region, both the angle of gaze needed to look at the monitor and the interpalpebral aperture are wider. On the other hand, when the monitor's center is lower than the intercanthal region, both the angle of gaze needed to look at the monitor and the interpalpebral aperture are smaller. Previous studies show that the angle of gaze is the most important risk factor that leads computer users to develop CVS. Symptoms associated with this syndrome are diminished when computer users gaze downward at angles of 14 degrees or more.
• Many patients with CVS complain of light sensitivity, which is worsened by fluorescent or flickering lights at the workplace. Computer users may have discomfort and glare from overhead fluorescent lights and large glass windows that are close to their workstations. Sheedy and coworkers believe that light sensitivity is worst in computer users, as compared to other office clerks, since computer users keep their eyes wide open to look at the monitor.2
Personal factors may also exacerbate the symptoms associated with CVS.
• Age and sex: Previous studies have shown that female patients, as compared to male patients, tend to have a reduction in the tear film's aqueous layer with increasing age.
• Uncorrected refractive errors may lead to blurred vision, asthenopia, eye fatigue, and headaches. Even though presbyopes may wear bifocals, computer users who wear bifocals may have to extend their neck to focus on the monitor, reading material, and/or the keyboard, which are usually located at intermediate distances. Neck extension for prolonged periods of time may also lead to neck pain and headaches.
• Symptoms associated with this syndrome, such as burning sensation of the eyes, may be exacerbated in computer users with preexisting dry eyes.
• Diseases that widen the interpalpebral fissures or lead to lid retraction, such as thyroid disease, may lead to increased tear evaporation.
• Diminished blinking: Studies by Yaginuma and Patel showed that computer users have a diminished blinking frequency.4,5 Normally, patients tend to blink approximately 18 times per minute. Patel and coworkers showed that computer users blinked only 4 times per minute.5 A reduced blinking rate in computer users may be part of an effort to gaze attentively at the computer monitor.
• Combined factors: Computer users who are presbyopic may need to extend their neck to look at the monitor through the bifocals. Symptoms may be exacerbated further by having an upward gaze to look at the computer's monitor.

Other Possible Diagnoses
Blepharitis, Adult
Conjunctivitis, Allergic
Dry Eye Syndrome
Lagophthalmos
Presbyopia
Refractive errors
Workup
Lab studies
A hormonal evaluation, such as a thyroid profile and sex hormones, may be needed.
Imaging studies
X-ray films of the neck may be needed to evaluate cervical vertebral curvature straightening in patients with neck pain. Orthopedic consultation or wrist MRI scans to evaluate the possibility of carpal tunnel syndrome may contribute to a complete diagnostic evaluation.
Other tests
Luminance evaluation by electrical engineers (when feasible) conducted at the workplace is advisable.
Treatment
A primary care provider should lead and coordinate the multisystemic evaluation of patients with CVS. Awareness of both the ocular findings and the systemic findings is essential in the management of patients with CVS.
Indications used for eyeglass prescriptions in the general population are also used for patients with this syndrome. Glasses should be prescribed for patients with refractive errors, including presbyopia. Occupational glasses may be needed by some patients with this syndrome. Single vision lenses versus bifocals should be chosen according to the patient's needs and working distances.
Medical therapy for dry eye symptoms as part of this syndrome includes the following:
• Topical lubricants
• Cyclosporine A ophthalmic emulsion (Restasis)
• Punctal occlusion
• Systemic therapy for dry eye or blepharitis
Surgical care
Surgical indications used for patients with dry eye syndrome are also used for patients with CVS. Some patients may benefit from punctal plug insertion.
Consultations
Since several ergonomic factors may contribute to CVS, engineer consultation is desirable at the workplace, including luminance evaluation of the working area.
A physical therapy evaluation is crucial in the diagnosis and treatment of cervical myositis and carpal tunnel syndrome in patients with this syndrome.

Medications
Vanishing preservative and preservative-free topical ocular tear replacement therapies are available.
Refresh Tears (Allergan), a lubricant eye drop, is available with varying characteristics and viscosities. Refresh Tears is supplied in 15 cc and 30 cc bottles, for repeated use, using the sodium chlorite Purite, a vanishing preservative system. A more viscous preparation, Refresh Liquigel is also available.
Systane Free (Alcon), a lubricant eye drop, is a structured gel in a bottle that contains the active demulcents polyethylene glycol 400 and propylene glycol and no traditional preservatives. Systane Free contains a novel system of proprietary ingredients that help form its gel structure and maintain its preservation, as follows: AMP (a pH adjuster), sorbitol, borate (buffer), and zinc. The combination of these ingredients produces a low viscosity droppable gel and a unique, ionic buffering preservation system. Original Systane is a bottled solution preserved with Polyquad and formulated at a pH of 7.0.
GenTeal (Novartis) is the original vanishing preservative tear replacement therapy. GenTeal is also available in a user-friendly nighttime gel.
Restasis (cyclosporine A ophthalmic emulsion) 0.05% is indicated to increase tear production in patients whose tear production is presumed to be suppressed due to ocular inflammation associated with chronic dry eye. Restasis has revolutionized the treatment of chronic dry eye disease, and it provides a preservative-free emulsion that also replaces both the aqueous and the lipid component of the tear film. Restasis should not be used by patients with active infections of the eye or by patients with known or suspected allergies to any of the ingredients in the formulation. Restasis has not been studied in patients with a history of herpes viral infections of the eye. The most common adverse effect (experienced by approximately 1 in 5 patients) following the use of Restasis is a burning sensation.
Follow-up
Further outpatient care
Evaluation and treatment of myositis and carpal tunnel syndrome are recommended.
In/out patient medications
Indications for prescribing ophthalmic medications for patients with CVS are the same as those for patients with dry eye syndrome.
Deterrence/prevention
Patients should avoid medications (eg, antihistamines, anticholinergics) that may worsen dry eye.
Computer users who have dry eye should avoid wearing contact lenses, especially in the late evening and at night when tear production is at its lowest.
Complications
Complications in patients with CVS are similar to those in patients with dry eye, including superficial punctate keratitis and keratitis.
Watch for optical decentration in eyeglasses by examining the patient's pupillary distance (PD). Consider using monocular PD measurements as needed. The patient's PD should be compared to the PD found in the eyeglasses. Consider advising the optician on the patient's dominant eye.
Watch for bifocal height malpositioning in eyeglasses. Consider advising the optician on the patient's dominant eye.
Prognosis
Early evaluation, diagnosis, and intervention may prevent the symptoms associated with CVS. Symptoms associated with this syndrome may be improved with lubricants.
Patient education
Educate employers and school administrators to conduct luminance and humidity evaluations at the workplace.
Proper monitor positioning to decrease the angle of gaze at the monitor will also help in preventing the symptoms associated with the syndrome.
Employees and students may benefit from educational programs about the symptoms associated with CVS.
