ESS Influx LPL-5 Laser Protective Goggles feature the ESS Adjustable Ventilated System (AVS) and a RotoClip™ that silently pivots the lens to enhance ventilation and reduce fogging. When the lens is closed, these mil-spec goggles are fully sealed against dust and debris. With impact-resistant lenses that meet or exceed ANSI and OSHA standards, these ESS goggles offer 100% UVA/UVB protection and feature 2.5 Optical Density that blocks 99.7% of 532nm wavelengths from green lasers.
