Despite criticism and early technical failures, the taming of liquid hydrogen proved to be one of NASA's most significant technical accomplishments. . . . Hydrogen -- a light and extremely powerful rocket propellant -- has the lowest molecular weight of any known substance and burns with extreme intensity (5,500Â°F).
The Solar Eclipse/Welding Glasses offered at myeyewear2go are ideally suited to any task or situation that involves eye-damaging light, including welding, solar eclipse viewing, and the viewing of direct sunlight. The green athermal shade 14 glass lenses utilized in these frames block over 99% of UV light and 97% of Infrared Radiation.
In fact, the National Safety Council, the American Welding Society, and the FDA all acknowledge that wearing contact lenses while welding is safe and even can provide UV protection. The only caveat is that contact lenses should not be used as eye protection in place of safety glasses or goggles. Once the proper goggles/shields are in hand, you can turn your attention to the type of helmet best suited for the job.
