An excessive amount of screen time can result in computer eye strain. This is also known as digital eye strain or computer vision syndrome. It occurs because observing screens requires our eyes to exert significant effort.
Numerous individuals gaze at their phones, devices, computer terminals, and televisions for extended periods of time. In fact, many modern occupations require employees to stare at displays for several hours per day.
In addition, many people use digital media or television to unwind after work. Therefore, there is little visual relief.
Continue reading to learn more about the primary causes and symptoms of computer eye strain, as well as some exercises and treatments for its relief.
Long exposure to digital displays can cause the eyes to exert more effort than usual. This can fatigue the eyes, which may result in the development of vision problems.
According to the American Optometric Association, the eyes experience greater strain when viewing displays than when reading printed text.
This is partly due to the fact that the letters on many displays lack the sharpness of printed letters. This is also due to the fact that many displays have less contrast than printed pages and are affected by reflection and sunlight.
All of these factors can make a reader’s eyes labor harder when viewing text on a screen.
There are additional factors that can contribute to computer eye strain. For instance, some individuals view screens from improper distances and angles. This can result in awkward and tense postures, particularly if the individual has underlying vision problems.
Furthermore, one reviewAccording to a reliable source, people’s blinking rate decreases significantly when viewing displays.
However, blinking is an essential biological function that maintains the cleanliness and lubrication of the eye’s surface. This decrease in blinking may also account for some of the symptoms of computer eye strain.
The following are some of the most common symptomsTrusted Source of computer eye strain:
- tired and strained eyes
- eye discomfort
- dry, irritated, or burning eyes
- blurred vision when viewing screens or looking into the distance
- difficulty refocusing the eyes
- sensitivity to bright lights
- headaches
- neck and shoulder pain
Exercises may aid in the prevention and management of computer eye strain.
For instance, the American Optometric Association suggests that individuals adhere to the 20-20-20 rule. Following this rule requires gazing at an object 20 feet distant for 20 seconds after every 20 minutes of screen time.
Additionally, it may be beneficial to invest some time each day performing additional eye-focus exercises. For instance, try steadily alternating between focusing on distant and nearby objects.
In addition, there is the figure eight. This requires observing a floor area eight feet distant. The individual should then move their eyes steadily in a figure eight pattern for 30 seconds in one direction, followed by 30 seconds in the opposite direction.
Other factors may aid in the prevention and management of computer eye strain.
For instance, one article from a reliable source suggests that modifying the environment could be advantageous. The authors of the study remark that regulating light intensity can aid in reducing pollution.
Additionally, various individuals require varying light intensities for labor. For instance, individuals over the age of 50 may require twice as much light as those in their twenties.
The authors also suggest optimal workstation configurations. For example, a person’s gaze should be approximately 35–40 inches (in) away from their computer screen. In addition, the screen should be approximately 5 to 6 inches below eye level.
Consider visiting a physician or undergoing an eye exam if your computer eye strain symptoms are causing you significant discomfort or impairment.
Additionally, it may be advantageous to research local vision therapists. Vision therapists can assist with computer eye strain by providing exercises and training. These include concentration and blinking exercises.
Some symptoms of computer eye strain may develop or intensify as a result of an underlying vision issue. Some individuals may be unaware of these issues. This may be true if they manifested later in life.
However, if a person suspects an underlying vision issue, it is imperative that they visit an eye specialist. An eye doctor can evaluate a person’s eyesight. This can help them determine the appropriate types of spectacles or corrective lenses for the individual.

As more and more occupations require extended periods of screen time, computer eye strain is likely to become more prevalent in the coming years.
Comparatively little research has been conducted on computer eye strain. The same holds true for its prevention and administration. Possibly the only surety regarding computer eye strain is that decreasing screen time is likely to be beneficial.
People can attempt exercises like the 20-20-20 rule, but if the problem persists, they should consult a physician or vision therapist. A more significant underlying condition may be at play.
There is some evidence to suggest that these exercises could assist with computer eye strain. For instance, according to one study, gazing at distant objects during work breaks can substantially alleviate the symptoms of computer vision syndrome.
Some scientistsAdditionally, reputable sources have suggested that blinking exercises may be useful for addressing computer eye strain. Some individuals may discover, for instance, that regaining a normal blinking rate when viewing screens alleviates some of their symptoms.
