Blue Light May Penetrate the Eye and Reach the Retina, Posing a Potential Health Threat

In our daily lives, sunlight is omnipresent, but it carries hidden risks. The solar spectrum is divided into three main parts: ultraviolet, visible light, and infrared. Visible light, which our eyes can detect, ranges from 380 to 780 nm and is split into seven colors: red, orange, yellow, green, blue, indigo, and violet. With the widespread use of LED technology, exposure to blue light has increased significantly. Devices such as televisions, computers, laptops, mobile phones, and tablets all emit substantial amounts of blue light. Unlike ultraviolet light, which is usually blocked by the cornea and lens and thus rarely reaches the retina, blue light behaves differently. Blue light is defined as visible light with wavelengths between 380 and 500 nm, and it is sometimes further divided into blue-violet light (approximately 380 to 450 nm) and blue-green light (approximately 450 to 500 nm). This type of light has shorter wavelengths and higher energy, making it capable of penetrating the cornea and lens, reaching the retina, and potentially harming eye health.

The Longer the Exposure, the Greater the Eye Strain
The impact of blue light on the eyes depends primarily on the duration and frequency of exposure. Prolonged exposure, especially during evening hours, can affect sleep quality and overall health. While the blue light intensity from electronic devices is generally low, continuous long-term use can gradually increase the strain on the eyes.

Frequent exposure to bright screens at night may lead to eye fatigue, blurred vision, and disrupted sleep patterns, as blue light can suppress melatonin production and delay sleep onset. Reducing screen brightness or using night mode can help mitigate these effects.

Oxidative Reactions and Retinal Damage

When the lens and retina absorb blue light, oxidative reactions may occur, generating free radicals. Accumulation of these free radicals can lead to cellular damage, potentially resulting in conditions like cataracts or macular degeneration. Such damage may cause distortions in the field of vision or impair color perception. For aging eyes, blue light's harmful effects are even more pronounced, exacerbating vision problems over time.

The Future of Blue Light Absorbers

Blue light absorbers have quickly become a focal point for industries involved in electronic displays and lens manufacturing. As the global reliance on electronic devices continues to grow, the importance of blue light absorption technology will only increase. By 2034, the market for blue light absorbers is expected to see a compound annual growth rate of 8.6%, with applications expanding across various sectors. We are committed to developing and launching a series of advanced blue light absorbers that will be widely applied in plastics, coatings, and digital displays, providing businesses with comprehensive blue light protection solutions while enhancing eye health for end consumers. Looking ahead, we will continue to bring innovative technology to the market, ensuring that the convenience of modern technology and vision protection go hand in hand.
