Recently, visual function defect has being social problem. Though people felt an incongruity are a few on using glasses and so on, the needs that seeing CRT without using correcting instruments is high, too. So we suggest the method sight revising on the part of CRT as new sight revising method. In the experiment, we made the image removed high frequency band, and then carried out an eye test using the image added high frequency band by linear function and logarithmic function to it. As a result, we could be sight revising by added high frequency band.
