All Zeiss lenses protect the eyes against UVA and UVB radiation up to 400nm. The VLT number indicates how much light passes through the lenses. Category 3. Allows 8-18% of light to pass through. Excellent in bright sunlight. Colours are reproduced in their original colours. For example, street, road and mountain biking, mountain, snow conditions, sea. Category 2 Transmits 18-43% of light. General purpose, for sunny and variable weather conditions. Eliminates blue and violet light. Improves depth of vision, contrast and works very well in fast species and situations where you need to judge distances. For example, road and mountain biking, skiing, golf. Category 1 Transmits 43-80% of light. Cloudy or rainy day glasses. Excellent in autumn and winter when light is not abundant but comes from a distracting direction. Protect the eyes and help to see variations in the shape of the ground and contrasts of light and shadow that cannot be seen with the naked eye. Polarised lenses Eliminate reflections and therefore work well in conditions such as at sea or on wet tarmac. Mirror lenses Allow less light to pass through. Usually intended for bright conditions.
