Projectors generally do not hurt your eyes. You should pay attention to using your eyes properly and avoid staring at the screen for a long time, otherwise you will experience visual fatigue. Projectors are usually used in classes or offices. They are a common device in life. The light bulbs used are generally halogen bulbs, which are relatively bright. If you only watch the light reflected on the screen, it will not hurt your eyes. However, if you look directly at the light emitted by the projector with your eyes, it is likely to harm your eyes. For example, there may be instantaneous burning of the macula, and macular edema in the later stage, which can easily cause vision loss. When using a projector, you need to be careful to avoid looking directly at the light emitted by the projector. Currently, some families will install projectors. When using them, you need to be careful not to use a projector with a brightness exceeding 5000 lumens, otherwise it will cause varying degrees of irritation to the eyes. In addition, you should pay attention to the correct use of the projector. For example, you should point the projector directly towards the wall or screen to achieve a better viewing experience. If the projector is facing diagonally towards the screen, the picture will appear elongated. In daily life, we should use our eyes reasonably and avoid looking at some electronic products. When visual fatigue occurs, we can look towards our eyes or look at green plants to relieve visual fatigue. |
