Eye health is a major consideration when deciding between a projector or a TV. Screens such as televisions produce direct blue light that is harmful to the eyes. Indirect light from a projector, or indirect blue light – is much gentler for the eyes. In addition to other safety features, projectors are the best option based on eye health.
Blue light is a wavelength of light that is found in natural sunlight and in luminous objects such as light bulbs, computer screens, and televisions. While most of the wavelengths in blue light are safe for your eyes, high-energy blue-violet light in the 415-455nm band is more damaging to the eyes, especially the lens and retina. This range of blue light belongs to ultraviolet intensity, which is known to be harmful to the human body if overexposed (which is one of the causes of our sunburn). Unfortunately, wearing UV-blocking sunglasses isn't ideal when it comes to your favorite movies or shows.
Blu-ray should be the first concern for people who are addicted to screen time. We spend hours at work, school, and at home, with our eyes glued to a screen, and the biggest screen we have is the TV. LCDs, LEDs, and all other TV varieties emit blue light, especially at night, which can adversely affect our health.
Projectors do produce blue light, but since you don't look directly at the light source when you're **, this light doesn't hit your eyes directly. Light is reflected off another surface (projector screen or wall) before it reaches your eyes;This surface absorbs some harmful wavelengths, reducing the amount of blue light that actually reaches your eyes.
Depending on the path to the eye, light sources can be divided into two types: direct light and indirect light. Most of the light sources we encounter every day, from the fluorescent lights overhead to the TV screen in the living room, are direct luminaires. This means that these items produce light and go directly into your eyes. Direct light sources are more harmful to the eyes as compared to indirect light. For example, staring directly at a flashlight beam is more uncomfortable than staring at the light reflected off a wall. Projectors make use of reflected light, which has less impact on your vision and reduces eye strain and other negative effects caused by long periods of time**.
Projector screen sizes make it easy to create images that are larger than TVs;Screens of more than 100 inches or even 200 inches can be easily produced. For those looking for eye comfort, the large screen of the projector is even better. A larger screen produces a larger, more eye-friendly image**. Reduce the need to see details with your eyes. It's even more beneficial for text, such as subtitles. Larger letters make the content easier to read. All in all, the projector offers a larger screen, reduces blue light, bypasses direct light, and utilizes reflected light, which equates to a more comfortable** experience than a TV.
All in all, in the comparison of TV vs projector, projector offers more flexibility while being safer for viewers' eye health. The projector reduces the effects of blue light and direct light while also offering an adjustable screen projection size, and newer projectors have smart safety features to avoid accidental eye injuries.
