How far away from your eyes is the best distance to hold your phone?
Using smartphones for hours every day has become a habit for many people. However, improper screen distance and incorrect posture can cause eye strain, neck pain, and various other health problems.
Staring at a brightly lit screen for extended periods, whether it's a computer monitor, television, or smartphone, can negatively impact your eyes and body. One of the most common problems is Computer Vision Syndrome (CVS), also known as digital eye strain.
This condition occurs when the eyes constantly have to adjust focus to track content on the screen, while the blinking frequency is significantly reduced. As a result, users may experience symptoms such as blurred vision, headaches, dry or irritated eyes, fatigue, and reduced concentration.
In addition, improper posture while using electronic devices is also a cause of many health problems. Bending your head too low to look at your phone or having to crane your neck to observe a screen positioned incorrectly can put significant pressure on your neck and spine. A very common mistake is placing the screen too close or too far from your eyes.
How far away should a phone be from the eyes?
According to the American Academy of Ophthalmology's recommendations, digital devices should be held at a distance of approximately 33-50 cm (about the length of an arm) from the eyes.
Meanwhile, many people have a habit of holding their phones only about 30 cm or even closer to their faces. This short distance forces the eyes to work harder to focus, increasing the risk of digital eye strain.
Therefore, if users want to reduce the unpleasant symptoms associated with using electronic devices, they should maintain a greater-than-usual viewing distance from their phones.
This is also why Apple added the Screen Distance feature to iOS 17 and iPadOS 17. This feature can detect when the device is held too close to the face and send a warning to the user.
The posture you use is just as important as the screen distance.
The distance from your eyes to the screen is important, but it's not the only factor determining visual health. Sitting posture also plays a crucial role in reducing eye strain and musculoskeletal problems.
Many people often make mistakes such as slouching, bending their heads too low, or maintaining one posture for extended periods. These habits not only cause immediate discomfort but can also lead to long-term health problems.

In particular, prolonged phone use with the head tilted down at about 45 degrees can cause technology-induced neck pain. This is a form of chronic neck pain that occurs when the neck and spine are subjected to constant pressure due to the prolonged head-down posture.
When the head is tilted forward, the weight bearing on the neck increases significantly, causing neck muscles to tense, shoulders to slump, and the spine to bear more pressure. Over time, this can lead to pain, stiffness, and reduced mobility.
How to use your phone to reduce eye strain and neck pain.
Experts recommend holding your phone in front of your body, at or near eye level, rather than placing it low under your chin. This posture reduces pressure on your neck while maintaining the proper distance between your eyes and the screen.
If you experience hand fatigue from holding your phone at a higher position, you can place a pillow on your lap or use a support to prop up your forearm. Additionally, maintaining an upright posture while sitting, keeping your head, neck, hips, and spine aligned, will reduce pressure on your musculoskeletal system.
For those who frequently view content on their phones or tablets for extended periods, a device stand is a useful solution. Many types of stands are now available to elevate the phone to a comfortable eye level, ranging from desktop stands and stands integrated with laptop kickstands to flexible arms that can be clamped to desks or other surfaces.
Regardless of the device used, maintaining a distance of 33-50 cm between your eyes and the screen, combined with proper posture, will significantly reduce the risk of digital eye strain, neck pain, and other health problems associated with prolonged electronic device use.
