What are Projectors?

Projectors are the latest devices that incorporate a network of light rays and lenses that are used to project a movie, web series, or slides on the screen. Usually, the screen is an imposing white wall of your workplace, living room, or backyard.

The size of the projecting screen varies from projector to projector. For example, Optoma HZ39HDR portrays a 200-inch image on the wall, whereas YABER V2 portrays 300-inch crisp images on the screen. Similarly, other features such as brightness, type of Keystone, number of lenses, etc., vary from one projector to another.

Are Projectors Detrimental to Your Eyesight Like TVs?

Well, if you are expecting the answer to be YES, then better luck next time! Because the answer is a BIG NO. Isn’t this shockingly weird?

Projectors eject indirect blue light, which is not much detrimental to the eyes. The blue light emitted by this device has little impact on the eyes as compared to the light rays emitted by Androids, PC, and TV screens.

TV screens emit direct blue light that results in irritability in the eyes if received continuously for hours on a daily basis. Such irritability can take worse shape if it is accompanied by redness, swelling, and pain in the eyes, eyebrows, or eye sockets.

If left untreated, it can result in permanent loss of eyesight. The such condition also comes with secondary health issues like more frequent headaches, neck pain, and acute pain in the facial bones surrounding the eyes.

At What Wavelength Blue Light Become Detrimental to the Eyes?

Indirect blue light emitted by the projectors has little to no impact on the eyes. Direct blue-violet light emitted by the TV screens at the wavelength of 415 to 455nm is exceptionally inimical for the eyes. The intensity of damage can be lessened by wearing UV light-resistant glasses. But the thing is, no one will enjoy a movie after putting on such heavy shades.

How are Projectors Less Damaging to the Eyes?

1. Projectors Emit Blue-Violet Light Indirectly

Like LCDs, projectors do produce a considerable amount of blue light rays. But these hazardous rays do not fall directly on the eyes. Instead, they fall on the projection screen. From the screen, it comes back to the eyes of viewers. In the process, the majority of the damaging rays are absorbed by the screen itself, so when the light falls on the eyes of viewers, they have already lost their credibility as damaging light rays.

2. Projectors Come With Wider Screens

Apart from being a source of indirect blue light, projectors have another plus point. The screen size of the projectors is incredibly tremendous, which means that you don’t need to put a lot of pressure on your eyes to see the minor details on the screen. With LCDs, the eyes of the viewers need to put additional effort into checking out all the minor and major details.


The projection screen of Optoma EH412ST, Short Throw Projector, is around 120-inches, whereas the projection screen of Yaber V2 is around 300 inches. TV screens are normally 45 inches long. Screens larger than 45 inches are too expensive to buy for the average household. If you are looking for a budget-friendly projector then don’t forget to check our article here.

3. Projectors Have Higher Levels of Brightness

The brightness of the screen matters a lot when it comes to the health of the eyes. Since projectors are present at a greater length from the actual viewing point and their brightness is relatively high in comparison to television screens, chances are that they will go light on your eyes. The higher the brightness of the projector is, the healthier it is for the eyes, meaning that viewers won’t have to put extra effort into understanding the details on the screen.


The brightness of the Optoma GT1090HDR Short Throw Laser Home Projector is around 4200 lumens – this brightness makes it the best option to use in broad daylight and dim light.

4. Projectors Have In-Built Eye Protection Feature

One of the key features of modern projectors is related to the safeguarding of eyes during the usage of a product for work or entertainment purposes. Such in-built features ensure the users that the creators of the projector take good care of their physical health in addition to taking good care of their mental health.

Viewsonic X10 4K projectors come with an in-built Eye Protection Feature, which is related to the protection of eyes during the manipulation of the projector. This feature turns off the lenses if any object comes too close to it so that the object would not receive any blue-violet light directly from the first source.

When Does Projector Become Harmful to the Eyes?

Projectors are normally less harmful to your eyes. However, it can be toxic for you if you directly focus on the light being emitted by the device. If you don’t look at the light source directly and with great focus, chances are that your eyesight will not get harmed.

Final Words

Projectors have become a crucial part of lives in most developed countries of the world, including the UK, the USA, and Canada. ‘Are projector better for eyes’ is the most common concern of most people, right? To be honest, they are not that detrimental to the eyes because they emit indirect blue light. Adieu!
