The increasing reliance on digital screens has led to a surge in demand for blue light glasses. China, a global manufacturing hub, plays a significant role in supplying these glasses worldwide.

Understanding Blue Light and its Effects
Blue light, a high-energy visible light, is emitted by digital screens and artificial lighting. While essential for regulating our circadian rhythm, excessive exposure can lead to digital eye strain, headaches, sleep disturbances, and potentially long-term damage to the retina. Blue light glasses mitigate these risks by filtering out a portion of the harmful blue light wavelengths. Heappy (www.heappy.com) highlights the importance of this protection in their detailed FAQ section.
Technical Features of Blue Light Lenses
Different manufacturers utilize various technologies to filter blue light. The effectiveness and visual impact vary depending on the chosen method. The following table compares common lens technologies:
| Lens Technology | Description | Blue Light Blocking Percentage | Visual Impact |
|---|---|---|---|
| Substrate Absorption | Blue light filtering material is integrated into the lens material itself. | 30-40% | Minimal to no noticeable color shift |
| Film Reflection | A coating on the lens surface reflects blue light. | 30-50% | Can cause slight glare or reflections |
| Hybrid (Absorption + Reflection) | Combines substrate absorption and film reflection for enhanced protection. | 60-80% | May have a slight tint, depending on the design |
