AIM: To evaluate the therapeutic effects of using prism effect in the correction of muscular asthenopia by changing optical center of presbyopic glasses.

Because of its superprism effect,as one-dimensional photonic crystal,this structure exhibits high spatial dispersion,which can be designed to be linear.

Based on its large group delay at the wavelength of peak transmittance,the superprism effect in this structure was numerically simulated.

The superprism effect was demonstrated experimentally in a thin film Fabry-Pérot filter based on its large group delay at the wavelength of peak transmittance.

Superprism effect opens new application to optical thin films, the thin film superprism can spatially separate light with different wavelengths when obliquely placed.

Studying the chromatic resolving power of prism by spectrometer;

Analysis of images caused by vertex angle of a prism and their application;

Explanation of Images Caused by Edges and Corners of Prism and Their Application;

Effects of combined training with CAMP vision simulating apparatus,convex lens and triple prism on AC/A in adolescent with myopia;

According to the laws of dispersion and complete reflection, the refractive indexes of water at different wavelengths are measured by use of a spectrometer and a set of triple prisms.

This paper presents the theoretical formula and experimental method for masuring refractiveindex of triple prism by any angle of deflection, and gives the comparison of the measuring results by minimum angle of deflection and both are almost the same in error.
