Prolonged computer use can lead to the development of Computer Vision Syndrome (CVS). Computer Vision Syndrome comes as a set of vision problems that cause discomfort in individuals who use computers extensively. The intensity of vision problems depends on the person, but in certain cases can be directly proportional to computer usage. The general symptoms of this condition are:
Straining of the eyes
Shoulder and neck pain
The cause of CVS is attributed to ergonomics. Poor lighting, inappropriate viewing distance, incorrect seating posture, computer screen glare, and outstanding vision problems are common causes of CVS. The extent of CVS experienced depends on the visual ability of the individual and the time they spend in front of a computer screen. Eye conditions such as farsightedness, astigmatism, aging, and presbyopia can add to the problem.
Although a majority of computer users experience these symptoms, they are only temporary. However, for some people, these symptoms can persist. Some individuals experience these vision problems even during non-working hours. If nothing is done to rectify these issues, the symptoms could become prolonged and even worsen.
CVS can be prevented by controlling lighting and glare on your computer screen. Proper viewing distances and computer viewing posture assure immediate relief. Also underlying vision problems can be corrected with LASIK laser eye surgery from Sugarland Eye & Laser Center in Houston.
Diagnosis of Computer Vision Syndrome
An eye examination can reveal this condition. During eye testing, emphasis is laid on visual needs in front of a computer, which includes:
Measurement of visual acuity to assess the effect of vision problems
Test to determine underlying eye conditions that might contribute to CVS
Refraction test to the lens power required to overcome refractive errors such as astigmatism, farsightedness or nearsightedness
Testing eye movement such as its focus and how eyes move together. In order to get a single, consistent and clear image, the eyes must be able to change focus and work together in unison.
Testing may be done without using eye drops to analyze how the eyes respond under normal viewing conditions. Eye drops may be used if the focusing power of the eyes is hidden or they may be used to keep the eyes from alternating focus during testing.
Treatment for Computer Vision Syndrome
There are various solutions for computer-related vision problems. CVS can be relieved with regular eye care and a change in user’s ergonomics. In some cases, individuals might be required to wear eyeglasses when using their computer. For those wearing glasses already, their prescription may be changed to accommodate requirements for viewing their computer screens. Their eyeglasses or contact lenses might need an upgrade such as changing the design of the lens, increasing the lens power, and introducing lens tints to enhance viewing abilities and comfort.
Vision therapy may be recommended for treating eye focus or coordination problems. These problems may not be corrected efficiently with eyeglasses or contact lenses. Vision therapy or visual training improves visual abilities of an individual and trains their eyes and brain to work together. These exercises remediate deficiencies in eye coordination issues. Changes in ergonomics are also recommended such as anti-glare screens, location of computer screen, seating posture, etc. As always it depends on the individual and the conditions they experience.
