The Impact of Excessive Smartphone Use on Eye Health: MYths and Realities

Excessive use of smartphones is a rising concern, affecting not only our eyes but various other aspects of our well-being. From eye strain to cardiovascular and mental health issues, the consequences of prolonged phone usage can be substantial.

Why Does Excessive Use of the Phone Damage the Eyes?

Traditional wisdom paints a grim picture, suggesting that watching anything on a screen, whether it's a phone, TV, or comics, can lead to vision problems. However, the reality is more nuanced. While prolonged adherence to small screens can indeed cause temporary eye strain and other visual discomforts, it does not necessarily lead to permanent vision damage.

Ben Wilkinson, FRCSC, an expert in the field, explains that 'eye strain' is simply a term for any discomfort around the eyes caused by making the eyes work. It arises from sustained muscle use and is not inherently dangerous. Much like how your legs or back get tired from too much physical activity, the muscles around your eyes can become fatigued from prolonged use.

Understanding Eye Strain

Eye strain can be caused by holding any muscles in a fixed position for an extended period, including the muscles in and around your eyes. This is why professional long-distance drivers take regular breaks to stretch and relax their muscles. Similarly, individuals who use computers or spend long hours reading or looking at screens should consciously take breaks to avoid eye fatigue.

The 20-20-20 Rule

A simple and practical solution to eye strain is the 20-20-20 rule. For every 20 minutes of screen time, you should look at something at least 20 feet away for 20 seconds. This gives your eye muscles a chance to rest and relax, reducing the chances of developing eye strain.

Dry Eye Syndrome: A New Condition

Another common issue associated with prolonged smartphone use is dry eye syndrome. Unlike true dry eyes, which are caused by a lack of proper tear production, dry eye syndrome is often a result of decreased blinking due to staring at screens. Screens reduce eye movement, leading to less blinking. This reduction in blinking can cause the surface of the eye to dry out, making it feel irritated and uncomfortable. This condition is not a new problem before computers, but it has become more common due to increased screen time.

Not Permanent Problems

It is important to note that eye strain and dry eye syndrome are not permanent conditions. They are primarily behavioral issues that can be managed and improved by adjusting your habits. Once you change your behavior, you can alleviate these symptoms.

Conclusion

In summary, excessive use of smartphones can cause temporary eye strain and dry eye syndrome, but these conditions are not permanent and do not lead to long-term vision damage. By understanding the difference between these conditions and taking steps to manage your screen time, you can protect your eye health and overall well-being.
