1.56 Semi Igqityiwe ifoto engwevu Iilensi zamehlo
I-lens yeglasi ye-lens yokuguqula umbala iqulethe inani elithile le-chloride yesilivere, i-sensitizer kunye nobhedu. Ngaphantsi kwemeko yokukhanya okufutshane kwamaza, inokubola ibe yi-athomu yesilivere kunye ne-athomu yeklorini. Iiathom zeklorini azinambala kwaye iiathom zesilivere zinemibala. Uxinaniso lweeathom zesilivere lunokwenza i-colloidal state, nto leyo esiyibona njenge-lens discoloration. Ukomelela kokukhanya kwelanga, ngakumbi iiathom zesilivere ziyahlukana, i-lens iya kuba mnyama. Ukuncipha kokukhanya kwelanga, iiathom zesilivere ezimbalwa ziyahlukana, i-lens iya kuba lula. Akukho kukhanya kwelanga ngokuthe ngqo kwigumbi, ngoko ke iilensi zingenambala.

Iilensi ezitshintsha umbala ziba mnyama xa kukhanya ilanga. Xa umbane uphela, ukhanya kwakhona. Oku kunokwenzeka ngenxa yokuba iikristale ze-halide zesilivere ziyasebenza.
Phantsi kweemeko eziqhelekileyo, igcina iilensi zicace ngokugqibeleleyo. Xa ibonakaliswe ekukhanyeni kwelanga, isilivere kwikristale iyahlukana, kwaye isilivere yamahhala yenza ama-aggregates amancinci ngaphakathi kwelensi. Ezi zidibanisi zesilivere zincinci aziqhelekanga, zidibanisa ezidibeneyo ezingakwazi ukuhambisa ukukhanya kodwa zifunxe, zibe mnyama lens ngenxa yoko. Xa ukukhanya kuphantsi, i-crystal reforms kwaye i-lens ibuyela kwisimo sayo esikhanyayo.
