Incorrect use of projectors can potentially lead to myopia.
Patients who use projectors at too close a distance, usually within three meters, and for too long are also prone to visual fatigue, which increases the risk of myopia.
In addition, if the contrast between the brightness of the screen and the surrounding environment is too high when using a projector, that is to say, if the patient feels blinding when looking at the screen, there is also an increased risk of visual fatigue, and excessive visual fatigue is easy to induce myopia.
In summary, if patients use projectors unreasonably, it is possible to cause myopia.
If you feel that your eyes are not seeing clearly and suspect myopia, you should go to the ophthalmology department of the hospital in time, and the doctor will confirm the diagnosis through optometry and guide the treatment.
