Material Specification

• Tinted Polarized Filters - supplied by a leading USA sunglasses lens manufacturer that designs and manufactures high tolerance polarizers for a variety of applications. It is a wholly owned subsidiary of a listed multinational corporation in the USA.
• Hinges are stainless steel.
• Steel plate used are oven-baked coloured galvanised steel.
• Magnets are nickle plated rare earth magnets (NdFeB).
• All sliding surfaces are lined with PTFE, which is a material that is used in non-stick kitchen utensil. This renders the surface very slippery and long lasting.

Polarized Filters

• Top of the line Yellow tinted polarized filters were chosen to form the rectangular panel to ensure optimum day light clarity. These lenses were designed to simulate the eye of the eagle (sharpens vision). These lenses eliminate 100 % Uv rays up to 400 nm.
• The other tinted polarized filter is chosen specifically to eliminate 96% of the blue rays of the sun so as to conform with the colour requirements of the traffic police regulation governing traffic lights. On their own they do not provide the same degree of clarity as the Yellow filter.
• Overlapping these 2 polarized lenses produces a seamless and variable intensity of tint that can reduce the sun to a dull orange disc and subdue various intensities of reflected suns rays, while providing optimum visibility
• Both these panels were chosen in cognizance of the advice from the ‘American Optometric Association (AoA)’ that recommended that the eye should be protected from Uv as well as Blue rays.
