Is projector better than TV for eyes? You probably have roamed around this question but never had the chance to explore the answer to the unsolved question. So yes, projectors are better for the eyes because TVs produce direct blue light, whereas a projector produces indirect light.
Now there can be various reasons for choosing a projector over a TV. You probably have concerns for your eyes and want them to stay in the best form.
So, qualities of a projector make it safer for the eyes? Stick to this article. We are here to help you understand the working phenomena of a projector and a TV. We will also discuss how a projector is better than a TV for your eyes.

Scalability & Image Resolution of Projectors
The first factor that differentiates between a TV screen and a projector is the scalability and image resolution both devices tend to provide. When we talk about televisions, they come in different sizes, each with a different resolution. One of the best TVs currently available in High-Definition televisions (HDTVs).
These TVs can also be considered an amazing choice for home theatres. The technology built in these TVs is 1080p; this helps the eyes as the higher the screen’s resolution, the easier it is for the human eye to bear. However, if you choose a 60-inch TV that has 1080p resolution, it is limited to screen size and fixed resolution.
On the other hand, a projector gives you the freedom to adjust and scale your image to the size you are comfortable with. In recent times, technology has advanced so well that now some of the projectors that are available in the market offer over 1080p resolution.
You can also scale your image up to 100 inches, which means that your eyes can focus on the screen without suffering from any strain on a projector screen, which can’t be done on a TV screen.
Emitted Light Vs. Reflected Light
Is projector better than TV for eyes? Both devices use different types of light, ideally making projectors better than TVs for the eyes. Here’s why. When a TV gets a signal, it goes through a cathode-ray tube (CRT) process.
The outcome of the process is a picture that is emitted to the user. The picture is emitted with the help of electrons and light through the TV screen. This way, the TV emits an image toward you. If we talk about modern TVs, the screens are significantly brighter compared to the older models.
Modern TVs tend to be 10 to 15 times brighter than the ones you currently use. If you wonder why manufacturers look forward to bringing more brightness to the screen, then the simple answer is better quality.
If your TV screen is brighter, you will have a crisper and more realistic image. This might be good for better quality, but in reality, this is quite the opposite for your eyes.
The brightness on the TV screen can cause headaches and can strain your eyes as well. And if your eyes are perfect with new TVs, they will be affected in the long run. However, when we talk about a projector, the light emitted from a projector is indirect.
This means that projectors don’t emit light directly to your eyes. This reduces the stress level on your optic nerve as the brightness of the light is significantly reduced. This is also why many prefer watching a movie on a projector rather than a TV screen.
Blue Light on TV Screen
Is projector better than TV for eyes? One of the main factors that make projectors better than TVs is because TV screens emit blue light. Whether it’s your LED, LCD, or any other TV type, all emit blue light. And the major problem is that we are glued to screens in our schools, offices, and home.
What’s more dangerous is that blue light is more effective at night and can negatively affect your health. An average American consumes 4.5 hours of screen time from a TV, and the amount of blue light it emits is simply devastating. So what are the effects of blue light on your body?
Blue light can lead to blurry visions, back pain, and irritated and dry eyes. You can even face difficulty focusing on tasks. However, in the long run, blue light can permanently damage your eyes and can contribute to the destruction of the retina.
How Can We Reduce Blue Light Exposure in Our Daily Lives?
One of the most obvious ways to reduce your blue light exposure is by reducing your daily screen time. This job isn’t going to be an easy one since you will need an alternative or something else to do to replace the unhealthy addiction of spending hours in front of the screen.
A report says that Americans usually spend over 10 hours a day consuming media. So, it’s almost impossible to reduce screen time to limit your exposure to blue light. If you are someone who works on a computer or someone who can’t work without a computer, then reducing your screen time is impossible.
However, if you are willing to reduce your screen time, you can limit the usage of your phone for browsing or consuming entertainment. A better solution to reduce blue light exposure is to go with projectors. Since the light emitted by a projector is indirect, your exposure to direct blue light is limited.
The working phenomena of the projector are simple, light bounces off a wall before reaching your eyes. The bouncing causes the wavelength of the light to decrease. Hence, reducing the blue light exposure as well.
Factors You Should Consider Before Buying a Projector
There are two main factors that you should consider before buying a projector. Below we have discussed both of them briefly.
Bulb Lifespan
If you didn’t know, projectors do have a light bulb in them. The bulb enables the light to travel from the device to the screen. However, the light is still better than your TV screen, but it comes at a cost. It usually depends on the type of projector that you buy.
Some light bulbs produce light that only lasts for a few thousand hours, and these bulbs can also be expensive. So, you need to know the price of the bulb used in your projector before investing in the projector itself.
Room Size
If you think that room size wouldn’t matter for your projector, you might want to reconsider your decision. Projectors, in general, are amazing for any size of projection you want. You can scale them to any size you want, but certain projectors are affected by the room size.
Some projectors like laser projectors since they are energy efficient, but at the same time, the projector can limit the ability to view your image on the larger screen.
Final Words
Now you know the answer to the question, is projector better than TV for eyes but more important is having control over your screen time as excess screen time can lead to a lot of unhealthy yet unwanted habits and can cause permanent damage to your body as well.
