The climax 590-a yellow spectacles have been designed to offer effective protection against the risk of impact from high-speed and low-energy particles and against ultraviolet radiation. the speed of the projectiles must be below 45 m/s. their special design minimally limits the lateral viewing angle and thanks to their optical neutrality and extreme lightness allow prolonged use without causing discomfort to the user. used in cases where better contrast is sought or in low-light environments
