Extended periods of looking at digital devices like smartphones, tablets, computers, and televisions can lead to a condition widely recognized as computer eye strain, also referred to as digital eye strain or computer vision syndrome. The strain on the eyes arises from their need to exert extra effort when viewing digital screens.
In our contemporary society, various occupations demand that individuals concentrate on screens for numerous hours throughout the day. Moreover, digital platforms and television serve as primary forms of leisure post-work, which can result in minimal rest for our eyes.
Continue reading to explore the primary reasons and indicators of computer eye strain, alongside various exercises and possible remedies that can alleviate its symptoms.
Causes
The intensive use of digital devices like computers and smartphones can lead to eye strain as the eyes exert more effort when staring at screens for extended durations. This strain can become a precursor to various eye health issues.
According to insights from the American Optometric Association, screen viewing typically causes more eye strain than reading print. One reason is that digital text isn’t as crisp as printed text. In addition, screens generally have poorer contrast with the background, not to mention their tendency to reflect light and create glare. These aspects can make it challenging for eyes when deciphering words on a screen.
Additional elements can also play a role in inducing eye strain from computer use. For instance, people may place their screens at unsuitable distances or angles, which could lead to awkward body postures and potential discomfort, particularly for those with pre-existing eye conditions.
Research also points out that there is an observed significant decrease in blinking while looking at screens. Given that blinking regularly is vital for keeping the eyes moist and clear of irritants, a reduced blink rate could be part of the reason for the discomfort linked to digital eye strain.
Symptoms
- Eyes feeling weary and overworked
- Discomfort in the eyes
- Eyes that are dry, itchy, or stinging
- Vision becoming hazy when observing screens or distant objects
- Challenges in adjusting focus between near and far
- Increased sensitivity to intense lighting
- Experiencing headaches
- Pain in the neck and shoulders
Practices to Alleviate Eye Strain
Adopting specific routines may aid in curtailing and managing the effects of eye strain from prolonged computer use.
One strategy recommended by eye health professionals, including those from the American Optometric Association, is the 20-20-20 rule. This involves refocusing the eyes on an object at least 20 feet away for 20 seconds after every 20 minutes of screen time.

Incorporating additional exercises for eye focusing into one’s daily schedule can also be beneficial. For example, it’s useful to regularly shift focus between a distant object and a closer one in a slow, deliberate manner.
Engaging in the figure eight exercise can be another helpful practice. To perform this, focus on a point on the ground approximately 8 feet in the distance. Move your gaze in a pattern that traces the number eight for 30 seconds in one direction, followed by another 30 seconds in the reverse direction.
Research supports the potential benefits of these exercises for countering computer eye strain. Findings from one investigation suggest that gazing at distant objects during breaks can significantly diminish computer vision syndrome symptoms.
Additionally, experts have highlighted the potential advantages of blinking exercises in confronting screen-related eye strain. Some individuals may notice symptom relief by reinstating a normal blinking rhythm while using digital devices.
When to see a doctor
Individuals experiencing considerable discomfort or disruption due to computer eye strain symptoms should think about consulting a medical professional or scheduling an eye examination.
Furthermore, exploring options for local vision therapy could prove beneficial. Vision therapists are equipped to offer specific training and exercises designed to address computer eye strain. These techniques often involve exercises to improve focus and exercises to encourage proper blinking patterns.
Glasses
Symptoms related to computer eye strain may emerge or intensify due to pre-existing, sometimes undetected, visual impairments. These may have developed gradually, hence individuals might not be immediately conscious of them.
Should someone suspect that they have an underlying eye concern, it’s essential to consult an optometrist or an eye care professional. Such professionals can conduct comprehensive vision examinations to ascertain if prescription eyewear or contact lenses might be necessary to correct the issue.
Summary
The prevalence of computer eye strain is expected to rise as modern work increasingly involves long hours in front of screens.
Research on computer eye strain and its preventative measures is relatively sparse. What does seem clear, though, is that limiting screen exposure could provide some relief.
While practices like the 20-20-20 rule may offer some benefit, persistent symptoms warrant medical consultation. It’s possible there is a deeper health issue contributing to the strain.
