As people’s daily screen time surges, harmful blue light from mobile phones poses growing threats to eye health, while rising privacy awareness demands stricter protection. As a professional tempered glass manufacturer, we proudly launch our innovativeRed Light + 28° Privacy Tempered Glass—a game-changer that solves two core pain points at once. Below is a detailed comparison between ordinary protectors and our cutting-edge product.
Most ordinary "anti-blue light" protectors fail to target harmful short-wave blue light (385-450nm) , while others completely block all blue light—causing over-protection . Worse, their colored filters distort screen colors significantly , forcing users to endure unnatural visuals. A 2025 test found that 68% of ordinary protectors reduce harmful blue light by less than 30% , offering almost no real eye protection.
Ordinary functional protectors (e.g., basic anti-blue light or low-grade privacy films) sacrifice light transmittance—often dropping below 85% . This makes screens dim even in well-lit environments, prompting users to crank up brightness, which accelerates battery drain and exacerbates eye strain . Long-term use leads to dry eyes, blurred vision, and even retinal damage, with 53% of users reporting eye discomfort after daily 3-hour screen time .
1.3 Lack of Privacy Shield: Sensitive Information at Risk
Standard tempered glass offers no privacy protection. In crowded spaces like subways, cafes, or offices, passersby can easily peek at your screen—exposing sensitive data such as bank details, work documents, or personal messages . Even basic privacy films on the market have wide viewing angles (30°+) , failing to block prying eyes effectively.
Ordinary protectors use low-quality coatings, resulting in poor anti-fingerprint performance—smudges accumulate quickly and are hard to wipe off . Their thin, brittle glass is prone to chipping or shattering upon minor impacts, leaving phone screens vulnerable. Additionally, many have poor adhesion, leading to bubbles or white edges that ruin the user experience.
Our product featurespatented quantum dot technology(SGS certified) that actively converts 47% of harmful blue light into therapeutic 650nm red light —a wavelength scientifically proven to benefit human health. Unlike ordinary anti-blue light films, it avoids color distortion and maintains 92%+ light transmittance , preserving the screen’s original clarity.
Red light offers multiple benefits: it reduces eye strain by relieving lens pressure (via LCA principle) , stimulates dopamine secretion to slow myopia progression , and improves Ocular microcirculation . Even during prolonged use (4+ hours), users report 50% less eye fatigue compared to ordinary protectors . It also eliminates screen glare in strong sunlight, keeping visuals soft and comfortable .
Equipped with an upgraded micro-prism array, our 28° privacy layer creates a "visual barrier" beyond 28° side angles . Laboratory tests confirm that side views are blurred instantly, reducing information leakage risk by 92% . Only the user directly facing the screen can see clear content—perfect for public spaces. Unlike wide-angle (30°+) privacy films, our 28° design ensures stricter protection without compromising front viewing experience .
