Is the projector damaging to the human eye, can it really protect the eyes? This needs to be verified from many aspects. First of all, we first compare the projector with the electronic products commonly used in life, which are TV, mobile phone, IPAD and so on.
Compared with electronic products such as TVs, mobile phones, and IPADs, projectors produce light that is not directed at the human eye, and the light emitted by electronic products such as TV and mobile phones is directed at the human eye, which is quite lethal to the eyes. , Especially when looking at Blu-ray quality things or when the picture flashes frequently, the damage is huge.
The light generated by the projector is irradiated on the curtain or white wall and enters the human eye through diffuse reflection, which prevents the light from directly illuminating the human eye, and weakens the damage to the human eye caused by the blue light and the flickering picture.
From this point of view, the damage of the projector to the eyes is indeed very small, but the projection market said that "the projector does not hurt the eyes" is also untenable. Using the projector to watch movies only reduces the damage of the direct light to the human eye, and The damage to the human eye is not completely eliminated, and the use of the projector for a long time can still damage the eyes.
Therefore, to reduce the damage to the eyes, or to protect the eyesight, all we need to do is to arrange the viewing time reasonably, and do not pursue too high brightness and contrast when viewing the film. Adjusting to the most comfortable level is the eye. The best protection.
