The projector screen can set according to your vision preferences. Projector has an inbuilt safety feature for the eyes.

Now you know that projector is good for the eyes. But why it’s better than TV for eyes, want to know to follow me.

Blue Light emission

Generally, there are two types of blue light natural and artificial both are found in the atmosphere we live in.

Natural blue light: comes from the sun which wavelength is 380 to 500 nm. Which is so intensive and has enough energy to be the reason for sunburn. Also, it can be the reason for eyesight issues if you see the sun directly.

Artificial blue light: comes from today’s digital screen, it’s wavelength is around 400 and 450. This is harmful to our eyes because today’s generation spent average time on screen is Six hours and 40 minutes. According to lifespan. Artificial blue light comes from TV and projectors.

In today’s TV CRT technology use to show the picture on the screen. In modern CRT (Cathode-ray tube) beams are bent by magnetic deflection.

To bent, the beams a deflection yoke is using, it’s the kind of lens that is used in the CRT, to scan the electron beam all over the screen vertically and vertically.

Modern TVs are more bright than older ones and their blue lights are directly falling on your retina. With continuous use of these TV, you can feel eye strain and headaches.

On the other hand projector light source made of HID or UHP, LED, Lasers, and combinations of LED and Lasers. These are the light source you will get in the modern projector. In the Projector, you will not see the projector light source directly that’s why it’s not intensive like TV.

Reflected light VS Emitting direct light

In the projector, the blue light that falls into your eyes is reflected light. Reflected light means the blue light which will indirectly fall on your eyes.

The blue light will come from the light source it reflects on the screen/flat surface then finally it will fall on your retina and you will see the images.

Which are a good thing, that’s why the projector hurt less than the TV. Its blue light not directly fall on your retina.

The way TV reflects his blue light is called Emitting direct light. TV directly reflects a blue light on your retina which is harmful to your eyes.

Modern TV is more bright than older TV. Which improves the picture quality. But not good for the eyes. When you see the tv for a long time you feel like your head is spinning and feel vomit, it’s not good for your health.

You can adjust the right distance between the TV and you. But here is a drawback you can’t adjust the size of the screen. The regular size of the TV screen you get on the market is 70″ (inches).
