Iiglasi zokuFunda zeMultifocus eziqhubela phambili Ukutshintsha umbala oBhulowu wokuKhanya uThintela ukuThuthuzelwa kokuFunda kweKhompyutha uMyili wokuFunda iiglasi ngokwesiko
Iiglasi zokufunda ezichasene nombala oluhlaza eziguqula umbala ziyindibaniselwano yeelensi ezitshintsha umbala kunye neendondo zokufunda eziluhlaza.
Umsebenzi wokutshintsha umbala: Iikhemikhali ezifana nesilivere ye-halide zongezwa kwi-lens, kwaye isakhiwo sezi zinto ziya kutshintsha phantsi kweemeko ezahlukeneyo zokukhanyisa, ngaloo ndlela utshintshe umbala welensi. Ngokomzekelo, ekukhanyeni okukhanyayo kwangaphandle, i-halide yesilivere kwi-lens iya kuphuka ibe yi-athomu yesilivere kunye ne-athomu ye-halogen, ii-athomu zesilivere kunye zenza umbala we-lens ube mnyama, ukuthintela ukukhanya okukhulu emehlweni; Emva kokungena kwigumbi, ukukhanya kuba buthathaka, i-halide yesilivere iphinda ihlangane, kwaye i-lens ibuyela ekuhleni.
Umsebenzi wokukhanya ochasene nohlaza okwesibhakabhaka: Ngokugquma umphezulu welensi okanye ukongeza izinto ezikhethekileyo, ukukhanya okuluhlaza okwesibhakabhaka okukhutshwe sisikrini sesixhobo sombane kunokukhethwa okanye kubonakaliswe. Ngokomzekelo, ezinye iilensi zinokuvala ukukhanya okuluhlaza okuyingozi kwibhendi ye-400-450nm, ukunciphisa umonakalo wokukhanya okuluhlaza okwesibhakabhaka kwi-retina yeliso, kunye nokunciphisa iimpawu ezingathandekiyo ezifana nokudinwa kwamehlo, ukoma, kunye nokudumba kweasidi okubangelwa kukusetyenziswa kwexesha elide izixhobo zombane.
