Ukutshintsha kombala okrelekrele otshintsha iilensi kunye nobukhulu bokukhanya kwe-ultraviolet, ukulungelelanisa ngokuzenzekelayo ubunzulu bombala, isibuko esinye sinenjongo ezininzi, akukho ngxaki yokutshintsha, ngaphakathi nangaphandle kulungele ngakumbi, ukhuseleko lwamehlo ngakumbi.
Ukutshintsha kombala okrelekrele kubonisa ukuhanjiswa kwesakhiwo se-shear, xa kubonakaliswe kwi-ultraviolet irradiation, i-molecule ivala ngokuzenzekelayo ukuvala ukungena kokukhanya, usebenzisa i-photoresponsiveness yayo elungileyo kunye nombala, ukuphendula ngokukhawuleza kwiinguqu zokukhanya, ngokufanelekileyo.
