Comparatively speaking, a projector will be better for your eyes than a TV. Projector is a device that can project an image or video onto a curtain, usually using the principle of light reflection, in which the light is weakened to a certain extent, and the reflected light of the projector will not have too much flickering stimulation compared to the direct light released from the TV set. Therefore, the projector is better for the eyes than the TV, but also need to pay attention to eye time. However, it should be noted that, whether watching a projector or TV, should pay attention to the viewing time, if too long, either one may cause some damage to the eyes. When watching a projector, people should also avoid looking directly into the light coming out of the projector. It is recommended that patients who experience eye discomfort after watching a projector or television for a long period of time should seek prompt medical attention to evaluate their condition and follow their doctor’s instructions for treatment.
