These thin film materials are infrared reflection film, selection transmit film, protection film, transparent conduct film, photocatalysis materials and so on.

The applications of reflected and red transmitted film have been analysed.

This paper has analys the reflectance IR of fibers treated with dyeing, UV lighting, soaping and friction, the results of which are that the dyes in the fiber have no influence on the reflectance IR, the fibers will be oxided under the UV lighting, the cotton fiber will appear a peak of 1700cm-1 after soaping and the friction actions only influence the crystal peak of the fibers.

The protocols included reaction to light stimulation,examination of external eye,reflection to red light and examination of fundus.
