How Retiguard ProShield Technology Works

How Blue Light Blocking Glasses Work: In-depth Analysis of Visionair Glasses and ProShield Technology

Understanding Blue Light Blocking Glasses

Blue light blocking glasses are designed to reduce the amount of blue light that reaches the eyes. Blue light, particularly from digital screens, has been linked to digital eye strain and disruptions in circadian rhythms, leading to sleep issues. The primary mechanism by which these glasses work involves filtering specific wavelengths of light that are most harmful.

Visionair Glasses: ProShield Technology

Visionair glasses by Retiguard feature the advanced Retiguard ProShield Technology (RPT), which represents a significant leap forward in blue light filtration. The RPT is specifically engineered to address the shortcomings of earlier blue light blocking technologies and offers a comprehensive solution for eye health.

The Science Behind ProShield Technology

1. Selective Filtering:

   • ProShield Technology is designed to filter out up to 99% of harmful blue light, particularly in the 380-450 nm range. This range is identified as the most harmful because it has higher energy and is more likely to cause retinal damage and melatonin suppression​.
   • Unlike older technologies that used amber-tinted lenses, which altered the perception of colors, ProShield lenses maintain color accuracy by selectively blocking harmful wavelengths while allowing beneficial blue-turquoise light (450-500 nm) to pass through. This selective filtering ensures users can enjoy natural color vision while being protected from harmful light​.

2. Lens Construction:

   • The lenses in Visionair glasses are constructed using multiple layers of advanced materials. These include a high-transparency substrate that ensures minimal light distortion and an anti-reflective coating that reduces glare.
   • Each layer is engineered to target specific wavelengths, effectively reducing blue light without compromising the overall clarity of the lens. This multi-layer approach is crucial for maintaining high optical performance while providing maximum protection​.

3. Photobiological Safety:

   • Research indicates that high-energy visible light (HEV), particularly blue and violet light, can cause phototoxicity, leading to long-term retinal damage. ProShield Technology incorporates filters that block these high-energy wavelengths, thus providing photobiological safety.
   • By focusing on narrow wavelength bands, the ProShield lenses ensure that the potentially damaging effects of blue and violet light are mitigated, while beneficial light frequencies are preserved. This approach not only protects the retina but also supports healthy circadian rhythms​.

Why ProShield Technology is Superior

1. High Efficiency in Blue Light Blocking:

   • ProShield Technology's ability to block up to 99% of harmful blue light is a significant improvement over standard blue light filters, which typically block only 20-40% of blue light. This high efficiency makes Visionair glasses exceptionally effective in reducing eye strain and improving sleep quality​​.

2. Maintaining Visual Clarity and Comfort:

   • Many blue light blocking glasses compromise on visual clarity by adding tints or reducing light transmission. ProShield Technology, however, uses high-transparency materials and advanced coatings to ensure that the lenses remain clear and comfortable for all-day wear. This is particularly important for users who need to maintain high levels of productivity and focus during prolonged screen use​​.

3. Comprehensive Benefits:

   • Visionair glasses with ProShield Technology not only reduce eye strain and improve sleep but also enhance overall eye health by preventing potential long-term damage from blue light exposure. The advanced design and materials used in these lenses also contribute to reducing glare and improving contrast, making them suitable for various lighting conditions​.

Conclusion

The advanced Retiguard ProShield Technology in Visionair glasses represents a cutting-edge solution for blue light protection. By selectively filtering harmful wavelengths while maintaining color accuracy and visual clarity, these glasses offer comprehensive benefits for eye health, sleep quality, and overall well-being. As the science behind blue light exposure and its effects continues to evolve, Visionair glasses remain at the forefront of innovation, providing users with the best possible protection against the challenges of modern digital life.
