Watching welding videos on your cell phone for a short period of time is often not harmful to your eyes. However, if you look at your cell phone for a long period of time at close range, there is a possibility that it may cause fatigue to the eyes and deepen myopia.
Welding is often harmful to the eyes because the light from welding irritates the eyes causing electro-optical ophthalmia, causing patients to experience discomfort such as foreign body sensation, tearing, and fear of light. Watching welding videos on a cell phone does not produce harmful rays such as ultraviolet rays, and is often not harmful to the eyes.
However, if the patient looks at the cell phone for a long time at a close distance, it is possible that the spasm of the ciliary muscle may cause local fatigue and discomfort such as soreness and swelling of the eyes, and may even deepen myopia.
It is recommended that patients use cell phones to watch welding videos, strictly control the time. If discomfort occurs, stop watching in time, if the discomfort can not be relieved, it is recommended to consult a doctor in time.
