Makes it visible in minutes
Follow the 20/20/20 rule
The human eye cannot concentrate at close range for long periods of time. Normally, the human eye travels near and far for seconds or seconds. Makes it visible in minutes. That’s why I like to read books closely. When using a phone, long hours of staring at the same distance may not be in harmony with the natural process of the eye.
Therefore, smartphone users should follow the 20/20/20 rule every time they use their phone. As a rule of thumb, you should minimize screen exposure by staring at a distance of 20 feet for at least 20 seconds after every 20 minutes of use. Another thing is that if you like to exercise, you can do short-term exercises for 20 seconds that will be good not only for your eyes but also for your body.
4. Adjust Brightness, Contrast and font size
Whenever you use your phone, you should adjust the brightness, contrast and font size depending on the ambient light conditions. By adjusting the contract brightness with the phone screen brightness, you can prevent eye damage. You can use third-party apps with the phone’s auto-tuning system to do this. There are many apps for Android and iPhone that automatically adjust Brightness and Contrast.
Avoid staring at your phone screen for long periods of time in low light conditions, and do not use your phone in the dark. The font size on your phone should be large. This allows you to easily find what you are looking for, reducing the need to focus on your phone and reducing the need for close-ups.
