Do projectors hurt your eyes?

Watching a projection for a short period of time is less harmful to the eyes.

If the projection screen is relatively small and in a dim environment, long-term or uninterrupted viewing of the projection increases the load on the eyes, resulting in, visual fatigue vision loss and other problems. If you look directly at the light of the projector for a long time, it may irritate the retina and cause serious damage to the eyes, such as macular edema. The occurrence of visual fatigue can have symptoms such as soreness and tearing of the eyes. If you use a projector with a small projection screen, in a dimly lit room, long-term viewing may cause vision loss, especially if you have problems with myopia and astigmatism yourself.

If you use a projector in an incorrect way, the light from the projector will shine directly on your eyes, which may irritate your retina and gradually cause vision loss and distortion. Therefore, when using a projector, pay attention to the combination of work and rest, avoid a long time or uninterrupted look at the projector. In addition, try to choose a projector with moderate brightness and a large clear picture, and pay attention to the laser projector's light can not shoot directly into the eyes. If there are symptoms of discomfort, you should seek medical attention.
