Excessive screen time can lead to various visual problems, including eye strain, headaches, and myopia, particularly in children. Experts recommend implementing the 20-20-20 rule, which advises taking a break every 20 minutes to focus on an object 20 feet away for 20 seconds. Additionally, proper desk ergonomics—like using a larger monitor, increasing font size, and maintaining a suitable distance from the screen—can further reduce eye strain. While some products like blue light glasses are marketed to combat these issues, studies suggest they may not be significantly effective.
Luckily, eye strain is temporary. The best way to avoid these symptoms is by taking breaks from our screens or near work activities and using lubricating eye drops, if needed.
By following the 20-20-20 rule, you give tired, tight muscles time to relax by focusing on something about 20 feet away for 20 seconds.
