Based on the latest ergonomic research, the Uvex Ultrasonic Safety Goggles combine hard and soft material components with high mechanical rigidity. These goggles never pinch or press the wearer's face, even when worn continuously. Whilst flexible soft components adapt seamlessly to the wearer's face, full lateral protection prevents the eyes from being compromised. Offering greater ventilation than previous models, the Ultrasonic goggles ensure the climate around the eyes is pleasant and non-irritant. These goggles are ideal for workers who require a wide field of vision and comfort over long periods.
