1. Are projectors better for your eyes than other digital devices?

Compared with traditional electronic equipment, the projector is the principle of diffuse reflection luminescence, the picture is the light hit the curtain or wall reflection to our eyes, compared with the mirror reflection brightness is more uniform, not too strong stimulation, really let people feel softer, more comfortable on the vision.

The projector screen is larger. The smaller the screen, the harder it is for your eyes to look. But the projector screen is large enough to give you more eye movement.

Compared with traditional electronic equipment, projectors are more protective of the eye, but be sure to choose the right one.

To protect your eyes, do not choose projectors with features below:

1. low brightness

Your eyes will be uncomfortable with too bright or too dark. Many projectors have low lumens, and it takes a lot of hard work to see the screen clearly, which will increase visual fatigue and eye burden.

A special note here is to look for ANSI lumens when purchasing. ANSI lumens are the actual brightness projected by projectors and are internationally recognized as the most formal and professional method of formulation.

2. Low resolution

Lumens measure brightness, resolution measures quality. This is also the core of a projector. The higher the resolution, the clearer and more realistic the picture, and the more realistic and detailed it will look.

3. Low filling rate

The chip's technology also affects the way the projector displays images, which is crucial for quality. (The higher the filling rate, the more realistic the picture)

LCD technology, the filling rate is about 60%, the screen will have obvious grille effect, the advantage is that the color degree is better.

DLP technology, the filling rate is generally above 90%, the picture is realistic, the advantages are fast response, long life, small size.

To sum up, if you buy the projector that its lumen, resolution basic parameters are not enough, plus the use of the scene is too dim, use the eye for too long, will cause damage to the eyes
