As we know that polarized sunglasses are very popular with the people who work outdoor. Because of the special design and perfect material, Polarized lenses can block 100% of glare. In this way, they help reduce eyestrain. Besides, Polarized lenses will also help enhance an image and its color so that your surrounding will have bolder and brighter colors and look clearer. But you should also know that even if they can protect your eyes from much light, they are not designed to protect you from the light from welding. Because the light from welding are so strong that polarized sunglasses donâ€™t have this function. So you should use some glasses which are specially designed for the welding.
