Миррор Рефлецтион оф Сунглассес

The lens of reflective sunglasses can reflect light like a mirror. The lens is coated with a very thin layer of reflective paint-because this layer of paint is very sparse, it is called a semi-silvered surface. The term "half-silvered" comes from the fact that the reflective molecules on the lens are very sparse, and the number is only about half of the number of molecules when the lens becomes an opaque mirror. At the molecular level, the reflective molecules are evenly dispersed on the surface of the lens to form a uniform film, but only half of the lens is covered by the film. This half of the silver-plated surface can reflect about half of the light that reaches its surface, and let the other half of the light directly pass through.

Usually, mirror paint is gradual, and the color depth of the paint gradually changes from top to bottom. This can enhance the resistance of the sunglasses to light from above, while allowing more light to enter from below and horizontally. This means that when you are driving, sunglasses can block the sun's rays while also allowing you to see the dashboard clearly. Sometimes, the paint is double gradient, the upper and lower parts of the lens have the highest color depth, and the middle of the lens is clear.

Кључни проблем са рефлектујућим наочарима за сунце је тај што се боја лако огребе. Очигледно, данас произвођачи наочара за сунце нису били у могућности да успешно прекрију површину рефлектујућег филма слојем против-гребања. Због тога је слој против-огреботина обложен на површини сочива, а рефлектујући филм је премазан на слоју против-гребања.
