Smart Projectors vs. TVs: Which Is Better for the Eyes?
By XGIMI Tech - 2022-09
LED screens have become mainstays in our homes, offices, schools, etc. While blue light is beneficial, continued exposure has proven harmful to eye health. Digital eye strain or computer vision syndrome and permanent retinal damage are some of the damaging eye defects resulting from overexposure to LED lights from TV screens and other sources.
By projecting onto reflective surfaces, smart projectors significantly reduce the effects of blue light overexposure on the eyes. While watching LED TVs will expose you directly to blue light, projector screens absorb most of the damaging rays, reflecting the projected display like the moon reflects sunlight.
XGIMI HORIZON Pro, AURA, and HORIZON are powerful home and laser projectors that offer low blue light exposure with diffused reflection imaging. This article will help you understand what blue light does to your eyes and how projectors compare to the best TVs for eye health and offer eye protection. In addition, the article will explore XGIMI projectors and their excellent features that protect your eyes and deliver a great viewing experience.
How Do Projectors Reduce Blue Light Exposure?
What Is Blue Light?
Blue light is one of the colors in the visible light spectrum— the white light we see from the sun and is why the sky appears blue. Blue light has a noticeably short wavelength, between 380 to 500 nanometers, and is a high-energy light. Artificially, blue light is found in digital screens (LED screens of TVs, smartphones, laptops, etc.) LED lights, electronic devices, and fluorescent lighting.
How Does Blue Light Get Into The Eyes?
Sunlight is the primary source of blue light. The blue light produced by your LED TV goes into your eyes the same way that which the sun produces does, but with far lesser intensity. Sunlight and blue light enter the eyes through the cornea to the pupil, from which it reaches the eye lens and the retina, passing the vitreous in transit. White light has at least seven lights within the visible spectrum. Blue light vibrates within this visible spectrum, with a short wavelength and high energy.
Is Blue Light Bad For Your Eyes?
Blue light has several health benefits. It prevents nearsightedness in children, and helps develop their eyes and vision. Also, blue light exposure regulates the circadian rhythm (the sleep-wake cycle) and also boosts memory and cognitive function.
Overexposure to blue light affects eye health significantly. Prolonged exposure to blue light leads to digital eye strain or computer vision syndrome, characterized by headaches, insomnia, eye strain, blurry vision, and dry eyes. In addition, research has proven that blue light overexposure can lead to retinal damage in adults, causing age-related macular degeneration (AMD).
How Projectors Reduce Your Exposure To Blue Light?
Projectors reduce blue light exposure significantly. Their light source casts an image on the screen/wall, and the reflected light is what enters the eyes, preventing direct exposure to the light source. The receiving surface absorbs most of the dangerous blue light rays and, with diffused reflection, sends the remaining rays to our eyes.
The moon is a natural example of the reflection procedure. It receives and absorbs most of the sun's rays, giving off a silvery color that you can easily look at without shielding your eyes. In addition, some projectors feature advanced diffused lighting technology that is hugely beneficial to eye health, especially for kids, as it reduces damaging blue light emissions.
