405nm 450nm Blue Violet Laser Safety Glasses

The Green-laser-glasses model is a pair of laser safety eyewear designed to protect the eyes from blue and violet laser radiation in the 405nm to 450nm wavelength range. These wavelengths are commonly used in laser engravers, 3D printers, fluorescence microscopy, spectroscopy, and medical or cosmetic diode laser systems. Even diffuse reflections from high-power blue/violet lasers pose a serious risk of retinal damage, making proper eye protection essential. These glasses use polycarbonate lenses with absorptive filtering that provides an optical density (OD) of 6+ across the 190–490nm range, attenuating the transmitted beam by a factor of at least 10⁻⁶. The visible light transmission (VLT) is approximately 50%, allowing adequate visibility of the workpiece while maintaining strong attenuation of the hazardous wavelengths. The frame is made of flexible polymer that adjusts for a comfortable fit and is designed to be worn over prescription eyeglasses. The lenses are lightweight, impact-resistant, and their protective performance is not compromised by surface scratches. These blue laser protection glasses are intended specifically for 405nm and 450nm blue/violet lasers and are not rated for red, green, or IR wavelengths. Users should always verify the OD requirement for their specific laser power and exposure duration before relying on any protective eyewear.
