Sleep at least 8 hours a night
Give up bad habits
Adjust the monitor so that the image refresh rate is 75 Hz
Keep your screen and workspace clean
Set the optimal distance between your eyes and the monitor - 70 cm.
Take a break between work once every 1-2 hours
Drink at least 1.5 liters of liquid per day
