Blu-ray technology is now a part of our daily lives, especially as we increasingly rely on electronic devices. Our eyes are constantly exposed to screens—smartphones, tablets, and TVs—throughout the day. From childhood, parents have warned us about watching too much TV, and now they add another rule: limit mobile phone use. But why are we told to reduce screen time? Many people blame blue light for eye strain and potential harm. However, do you really understand what blue light is?
Blue light is part of the visible light spectrum, with wavelengths between 400-500 nm. It's close to ultraviolet (UV) light, which is known for its harmful effects. While UV light can damage skin, blue light, due to its shorter wavelength, carries higher energy. This has led to concerns about its impact on our eyes.
But not all blue light is bad. The harmful range is between 415-455 nm, while blue light in the 455-500 nm range plays an important role in regulating our circadian rhythm, mood, and memory. The danger comes when exposure is intense or prolonged, especially at high brightness levels.
The main risks of blue light include eye fatigue, long-term vision loss, and even retinal damage. Prolonged exposure may increase the risk of macular degeneration and cataracts, especially in children whose eyes are still developing.
To protect your eyes from blue light, many TVs offer built-in "eye protection" modes. However, these often alter colors, making the image look less natural and potentially increasing eye strain over time. Another option is anti-blue light films, but they’re expensive, hard to apply without bubbles, and only block up to 30% of harmful blue light.
A more effective solution is optical blue light technology. Skyworth’s G6B series TV uses this advanced method by adjusting the backlight source to reduce the harmful blue light band before it even reaches the screen. This approach removes harmful blue light at the source, ensuring clear visuals without compromising eye comfort.
Testing showed that the Skyworth G6B emits significantly less blue light compared to a regular LCD TV. Its optical anti-blue light technology is both effective and practical, making it ideal for families who spend a lot of time in front of the TV.
With the growing role of TVs in education, entertainment, and fitness, protecting eye health has never been more important. For children, in particular, optical blue light technology offers essential protection. As screen time increases, so does the need for smart, safe viewing solutions.
