One difficulty in choosing your safety eyewear is which colour lenses to go for. Interchangeable lenses can solve this problem very cost effectively. Most include three lens sets - grey smoke lenses for bright sunny days, yellow lenses improve both contrast and depth perception on flat light days and clear lenses may be needed in very dull conditions.
These safety sunglasses are made to high quality specifications in order to meet the requirements of the European CE EN-166-F and American ANSI Z87.1 standards. They must pass six different tests for optical quality plus three different tests for impact resistance including a test that shoots a 1/4 inch steel ball at over 100 mph and leaves no more than a dimple on the lens.
