Looking at the screens of your computer, smartphone, and other digital devices for extended periods will not cause permanent eye damage. However, it can make your eyes feel dry and tired. You may experience burning in the eyes, end-of-day blurriness, stinging, tension, and fatigue. Some people may experience headaches and dizziness while viewing 3D images, which is an indication of problems with the viewer’s ability to focus and perceive depth (STEREOPSIS). Therefore, people with eye misalignment or lazy eye are advised not to watch 3D films…

Normally, people blink about 15 times per minute. However, studies have shown that when we use computers and other devices with digital screens, this rate often drops to about one-third of the normal blink rate. People also forget to blink while reading because they are focused, and the tear film layer that moistens and lubricates the eye surface evaporates quickly in eyes that remain open for long periods, leading to dryness. Therefore, prolonged reading or fine detailed work can also cause eye fatigue and dryness.

Smart buildings and office environments are often air-conditioned, which contributes to eye dryness. Shopping malls and terminals, where spotlights and intense lighting are heavily used, also frequently cause eye dryness and fatigue.

People working in front of computers and digital screens should blink more frequently to combat dryness, and take short breaks from the screen periodically to prevent tension and eye fatigue. Looking into the distance or horizon for a few minutes will help rest the eyes.
