The shade number on welding lenses indicates the intensity of light radiation that is allowed to pass through a filter to your eyes. According to OSHA, the higher the shade number, the darker the filter and the less light radiation that passes through the lens.

For solar eclipse observation, welding shade 14 is the only approved and recommended by NASA. Ultimately, these solar eclipse lenses block 99 percent of ultraviolet light and 97 percent of infrared radiation. All lens material used for Phillips Safety’s solar eclipse lenses has been certified to be Shade 14 by DIN Certo, Class 1 by notified body 0196 CE. In addition, they meet all Transmission Requirements as specified by ISO 12312-2:2015 for direct solar observation.

Our goal at Phillips Safety is to provide customers with welding lenses that provide the highest protection during welding procedures. That being said, our green welding lenses start at $2.99, with many options to choose from.

The shipping of welding safety products changes according to its category. Welding safety glasses, for example, usually take between 3 and 5 business days to be shipped. Our welding lens and clip on flip up welding glasses also take between 3 and 5 business days to be shipped. Phillips Safety is committed to getting your order out quickly and efficiently while doing proper quality control.

To choose the right welding lenses for you, you must consider the color and IR shade that you need. They must have filter lenses with a shade number that provides the appropriate level of protection. A shade number indicates the intensity of light radiation that is allowed to pass through a filter lens to one’s eyes. Therefore, the higher the shade number, the darker the filter and the less light radiation that will pass through the lens. To guide you, OSHA’s tables available on this link lists the minimum protective lens shade numbers for commonly used welding and cutting processes.
