Outline of Final Research Achievements

As a result of examining the effect of wearing a contact lens (CL) by visualizing the heat transport in the eye by injecting a thermo-sensitive liquid crystal capsule (fine particles changing color by heat) into the eye, CL wearing showed shomewhat the effects of reducing corneal temperature elevation. We investigated the absorption characteristics of millimeter waves (MMW) using Terahertz time-domain transmission spectrometer for color CL (metal paint may absorb MMW), but there was no significant MMW absorption by color CL.As a result of visualizing the transpiration state of the heat to the outer eye part during exposure to millimeter waves (MMW) by creating a chamber that fits the outer eye part of rabbits, CL wearing had no clear effects of suppress or reduce of ocular damage.
