Whether you're working, studying, socializing, or even relaxing, you're most likely looking at a screen. This increased usage of digital devices has given rise to a new concern: screen time. But have you ever stopped to wonder what all this screen time could be doing to your eyes? More specifically, is spending seven hours on screens bad for your eyes?
The Impact of Prolonged Screen Time on Eyes
Long hours of screen time can lead to a condition known as digital eye strain or computer vision syndrome. This condition is characterized by symptoms such as dry eyes, blurred vision, and headaches.
The main cause of these symptoms is the constant focusing and refocusing that your eyes do when you're looking at a screen. This, coupled with the glare and contrast from the screen, can lead to eye strain. In addition, staring at a screen can reduce your blink rate, leading to dry eyes.
How Much Screen Time is Too Much?
While there's no universal answer to this question, spending seven hours or more on screens daily could potentially harm your eyes.
According to the American Optometric Association, individuals who spend two or more continuous hours at a computer or using a digital screen device every day are at the greatest risk of experiencing digital eye strain. However, with many adults spending more than seven hours a day on digital devices, the risk becomes even higher.
It's important to note that the impact of screen time on your eyes can vary based on other factors as well, including your overall eye health, the setup of your digital devices, and how often you take breaks.
How to Reduce the Impact of Screen Time on Eyes
While it might be difficult to reduce your screen time significantly, especially in the digital age, there are ways to mitigate its impact on your eyes.
Firstly, ensure you're taking regular breaks from your screen. The American Optometric Association recommends the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This can help reduce eye strain.
Secondly, adjust your workspace to ensure its eye friendly. This includes positioning your screen around 20-26 inches away from your eyes and slightly below eye level. Also, ensure the lighting in your room is sufficient, and consider using a screen glare filter.
Lastly, don't forget to blink regularly to prevent your eyes from drying out. If you already have dry eyes, consider using lubricating eye drops.
Balancing Screen Time for Eye Health
By understanding screen time and its impact on your eyes, you can take steps to protect your eye health. This includes taking regular breaks, adjusting your workspace, and blinking regularly.
