Additionally, when using computers, many people forget to blink. Usually we blink around 15 to 20 times per minute, but when reading a screen, we often blink only half that amount. All of that staring can dry out your eyes, which contributes to the irritation. However, rest assured that you are probably not doing your eyes permanent damage.
While computer vision syndrome may be unpleasant, if you take some time off from the computer, your eyes will get the rest they need and start feeling better again. Viewing computer screens for hours can affect more than your eyes. Most screens are backlit with blue light, which can interfere with your sleep cycle. The researchers believe that the blue wavelengths electronic screens emit interfere with the production of melatonin, a sleep-promoting hormone.
The most obvious change is to cut down on your screen use, especially in the hour or two before bedtime. Try the solutions below. Gardiner says. Eyestrain can also result from focusing up close on a screen without the proper eyeglass prescription. You can exhaust your eyes' ability to focus," says Dr.
Some research has even suggested that eyestrain may result from difficulty focusing on the text and images on computer screens in particular, since they're made of pixels that create blurry edges.
Fortunately, eyestrain and dry eyes are easily treated. Gardiner recommends using artificial tears several times throughout the day. The artificial tears don't have to be preservative-free. Another tip: remind yourself to blink from time to time. If you have eyestrain and headaches after looking at the computer screen for long periods, make sure your eyeglass prescription is up to date.
Once the person gets reading glasses, the headaches are gone. Adjusting your environment can also help reduce the risk for developing computer vision syndrome. Some ideas:. Make sure the center of the computer monitor is slightly lower than eye level — four to eight inches.
Gardiner's best advice: take a break from electronic screens every 15 to 30 minutes, just for a minute. Do something else, and refocus on a distant target. World globe An icon of the world globe, indicating different international options.

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, the position of the monitor, and the use of rest breaks. Regular eye examinations and proper viewing habits can help to prevent or reduce the development of the symptoms associated with CVS. Prevention or reduction of the vision problems associated with CVS or digital eyestrain involves taking steps to control lighting and glare on the device screen, establishing proper working distances and posture for screen viewing and assuring that even minor vision problems are properly corrected.
Acanthamoeba is one of the most common organisms in the environment. Although it rarely causes infection, when it does occur, it can threaten your vision.

Uncorrected vision problems. A combination of these factors. Diagnosis CVS, or digital eyestrain, can be diagnosed through a comprehensive eye examination. Testing, with special emphasis on visual requirements at the computer or digital device working distance, may include: Patient history to determine any symptoms the patient is experiencing and the presence of any general health problems, medications taken or environmental factors that may be contributing to the symptoms related to computer use.
Visual acuity measurements to assess the extent to which vision may be affected. A refraction to determine the appropriate lens power needed to compensate for any refractive errors nearsightedness, farsightedness or astigmatism.
Testing how the eyes focus, move and work together. In order to obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work in unison.
This testing will look for problems that keep the eyes from focusing effectively or make it difficult to use both eyes together. Treatment Solutions to digital screen-related vision problems are varied. 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.
