It usually arises when the individual is watching excessively the digital screening and has been facing some vision problem. There are so many people who now have experienced vision issues and even eye discomfort while watching the digital screens for quite some time. The discomfort level keeps on increasing with digital screen usage.
Risk factors and causes to not ignore:

There are certain angles and distances set for viewing from the screen. However, not everyone follows such a rule. Because of this, the focus of the eye and moments of the eye also gets hampered and the
There are some under corrected or maybe uncorrected vision issues that may cause major trouble and be associated with computer-based eyestrain. Some people even have eyeglasses prescribed for regular use but when they adjust the viewing distance of the screen, they are likely to get the strain.
There are so many scenarios in which the CVS signs usually occur only due to the visual requirement that the digital screen demands. This could happen to those people who usually spend more than 2 hours continuously on the computer or any other digital screen every time.
