What is a UV mirror? UV is the abbreviation of the English word Utlraviolet, which means ultraviolet light. UV mirror can filter out the ultraviolet rays in the sun, so it is also called ultraviolet filter. Because the UV lens can not only improve the imaging, but also protect the lens from dust, fingerprints and other pollution. and so. uV lens is always installed in front of the lens without taking it off, becoming the most widely used color filter
I think the most common filter is the UV lens. It is better to say that it is the best protective lens for digital camera lenses than it can improve the photo effect. During the trip, wind and rain are inevitable, and seemingly inconspicuous sand and dust may become the deadly killer of the delicate lens! This is the role of the UV lens. It not only prevents rain or other water droplets from invading the lens, but more importantly, it can effectively prevent the coating on the lens from being scratched by sand. Therefore, a good UV mirror is essential for traveling.(Note: UV lenses were previously used to absorb ultraviolet light, but this effect has been weakened in digital cameras. Therefore, most people now use UV lenses for digital cameras to protect the lens.)
