If there is visual fatigue, the symptoms of blurred vision need to rest your eyes. How long it takes is related to everyone's physique, and it is also related to the time of using eyes. Visual fatigue of eyes is mostly due to abnormal energy exchange caused by nerve fatigue, which in turn leads to ametropia and blurred vision. Eye drops can be used under the guidance of a doctor.

Asthenopia is a common eye disease, which causes dry eyes, astringent pain, blurred vision and even decreased vision, and directly affects people's work and life.

Eye fatigue is mainly due to the fact that when people concentrate on watching the screen of electronic products such as TV, computer or mobile phone, the number of blinks in their eyes decreases, resulting in a corresponding decrease in tears secretion, and the flashing screen strongly stimulates their eyes. Eye fatigue can also cause and aggravate various eye diseases. The best way to relieve eye fatigue is to rest your eyes.

Ways to relieve visual fatigue:

Pay attention to the light, reading in dim light won't hurt your eyes, but if the light can't provide enough contrast between light and shade, it will easily make your eyes tired.

Interrupt your work. If you use the computer for six to eight hours in a row, you should rest for two to three hours, have a cup of coffee, go to the toilet, or just keep your eyes off the computer for ten to fifteen minutes.

Reach out and rub your hands until they are warm, then close your eyes and cover them with your palm. Take a deep breath for 20 minutes every day.
