Is projector good for eyes? Can projectors hurt eyes or cause eye strain? Buying a big screen smart tv vs home theater projector, which one is the wise choice? Eye health is a big concern when determining projector vs. TV. Screens such as TVs emit eye-damaging intense blue light. The Ambient Light of the projector – including the blue light – becomes much gentler for the eyes. In comparison to other protection features – as you can hear about below – projectors are the safest choice based on eye health.
Is Projector Better for Eyes Than TV?
Is projector safe for eyes? TV vs projector for your eyes, which one should you choose for your next home entertainment setup? There are many important factors to consider such as cost, screen size, and image quality, but those are features of the product itself. What about consideration to effects of the product on the user, in this case, you and your family, who will be spending hours enjoying TV programs, movies, and streaming content on your new home entertainment system? If selecting a solution that will have the least effect on your health, especially your eyes, there are some issues you may not have considered before.
Avoid Blue Light Eye Damage
When comparing TV vs projectors, the blue light will be the first concern for people who are addicted to screen time. We spend hours at work, school, and home with our eyes glued to the screens, and the biggest screens we've got are our TVs. LCD, LED, and all other TV varieties emit blue light, which, particularly at night, has harmful effects on our health. With the average person in the US watching live TV more than 4.5 hours a day, according to research company Nielsen, the amount of blue light we get from our TV is pretty high.
According to www.bluelightexposed.com, blue light is the source of digital eye pressure, a medical condition with severe effects, including blurred vision, trouble focusing, dry and irritated eyes, headaches, and neck and back pain. In addition, long-term studies show that high rates of long-term blue light exposure can cause irreversible eye damage and lead to the deterioration of the retina and macular degeneration.
How Does Blue Light Damage Your Eyes?
Blue light is the color of light present in natural illumination and artificially from objects that emit light, such as light bulbs, computer screens, and televisions. Although most wavelengths of blue light are safe for your eyes, high-energy blue-violet light in the 415-455 nm band is more harmful to the eyes, particularly the lens and the retina. The spectrum of blue light falls below UV intensity, which is generally considered to be harmful to the human body if overexposed (one of the reasons for sunburn). Unfortunately, wearing Ultraviolet light blocking sunglasses would not be ideal if you tried to watch your favorite movie or show. What Can We Do to Cut Back on Blue Light Exposure?
One way to minimize the sensitivity to blue light is to minimize the reliance on your screen. The chance of this happening is slim. The same Nielsen report indicated that the average American adult spends more than 10 hours a day on screen consuming media. Cutting back is really difficult or impractical for most people, particularly if people have to work with a computer and spend the rest of the day watching their smartphones and watching a favorite TV show when they get home.
Projectors are an alternative to blue light-emitting TVs. Projectors do emit blue light, but because you won't be looking straight at the light source when you're watching this show, it doesn't reach your eye directly. The light bounces off another surface (a display screen or wall) until it enters your eyes; this surface absorbs some of those harmful wavelengths, minimizing the amount of blue light that actually enters your eyes.
Projectors do have several other benefits over TVs, such as less blue light, flexible screen sizes.
The Effects of Direct or Indirect Light Sources to Eye Health
Light sources could be categorized into two groups, depending on the direction taken to your eyes: direct and indirect light. Any of the light sources that we experience every day from the fluorescent lights over your heads to the TV displays in your living room are clear light emitters. This implies that such artifacts emit light and flow straight to your eyes. Indirect light sources are softer on the eyes relative to direct illumination. To explain this, looking squarely at the flashlight beam is a lot more awkward than gazing at the light reflecting off the mirror. Projectors use reflective light, which is less harmful to the eyesight and eliminates eye pressure and other adverse consequences of repeated watching. Screen Size – Bigger Is Better.
The screen size of the projectors can easily generate images larger than what is possible for TVs; a screen of more than 100 inches or even 200 inches can be easily created. For those looking for eye comfort, the wide screens of the projectors are even better. Bigger displays produce pictures that are bigger and more convenient for the eyes to see. Reduce the need to strain your eyes to see the details. With text, like subtitles, this is even more important. Larger letters make it a lot easier to read. Altogether, projectors provide bigger displays, decreasing blue light, avoid direct light, and use reflective light, which is a much more relaxed viewing experience than TVs.
The Bottom Line: Projectors Are Better for Your Eyes
To sum up, in the contrast between TVs and projectors, the projector provides a lot more versatility while being much better for viewers' eye safety. Projectors minimize the effects of blue light and direct light while still providing customizable display size projections.
If you are considering a new projector vs smart tv, consider the impact on your eyes. Take a break from a lot of screens in your life and try a projector.
