Replica Oakleys chemical

Before buying, you can do a simple test to identify its authenticity.Find a reflective surface, and then take the sunglasses, through a lens to look at the surface.Slowly rotate it ninety degree will sunglasses, observe whether reflected glare is to reduce or increase.Replica Oakleys
If sunglasses are polarized sunglasses, then you will see a dramatically reduce glare.
When sunglasses mirror exposed under the sunlight, the color will darken called color glasses sunglasses or prescription glasses.Color lenses mainly depends on the principle of the ultraviolet a special kind of chemical reaction.
Color lens contains certain substances (such as silver chloride or silver halide) of millions of molecules.When there is no ultraviolet rays, Knockoff oakley sunglasses
visible light can penetrate these molecules, and visible light is the general part of artificial light.But when exposed to the sun's ultraviolet rays, the molecules will pass by a chemical process, wholesale replica oakley sunglasses making them the shape of the change.New molecular structure can absorb part of the visible light and makes the lenses darkened.Shape change the number of molecules will change as the change of intensity of uv light.Polarized sunglasses test results
Sunglasses when you came to the room, leaving the ultraviolet irradiation, the corresponding chemical inverse change will happen.Suddenly left the ultraviolet irradiation, the molecules will be quickly restored to the original structure, to absorb the light of the properties.Whether it is or reverse changes, Imitation Oakleys the speed of the whole process occurs very quickly.
