Crusheyes - NOSTALGIC; 45% Blue Light Filtration, Anti-Fog Coating, Anti-Reflective Mirror, Comfort-LITE Frame, Lifetime Warranty  - Gloss Black

The manufacturer, Crusheyes, provides a Limited Lifetime Warranty for both labor and parts. This warranty covers any defects in materials or workmanship for the lifetime of the product.

The NOSTALGIC frame combines a timeless optical silhouette with modern blue light lens technology. Its design is characterized by a classic shape that has been updated with features such as anti-reflective lenses and blue light filtration, making it stand out from other glasses by blending retro aesthetics with contemporary functionality.

The anti-fog coating on Crusheyes NOSTALGIC glasses works by creating a hydrophilic layer on the lenses that attracts water molecules and spreads them evenly, preventing the formation of small water droplets that cause fogging. This ensures clear vision even in humid or moist conditions.

The 45% blue light filtration technology in Crusheyes NOSTALGIC glasses works by selectively filtering out 45% of the harmful blue light emitted by digital devices and screens. This helps protect the eyes from potential damage caused by prolonged exposure to blue light, such as digital eye strain, sleep disruption, and age-related macular degeneration.

The Crusheyes NOSTALGIC glasses offer 45% blue light filtration, which is the highest in the industry. They also feature anti-fog lenses and anti-reflective coating to protect the eyes from harmful glare. Compared to other brands, the Crusheyes glasses provide excellent blue light filtration and overall eye protection.
