Re thabela ho phatlalatsa sehlahisoa sa rona sa morao-rao: likhalase tsa mahlaseli tsa boleng bo phahameng tsa acetate.

Likhalase tsena tse peli li na le foreimi e entsoeng ka acetate ea boleng bo phahameng, e bobebe le e bonolo. Mebala ea foreimi e ruile ebile e fapane, e eketsa ponahalo ea eona e tloaelehileng. Ho feta moo, re fana ka mefuta e mengata ea mebala ea lense e ka bapisoang habonolo le mefuta e fapaneng ea mefuta. Ho sireletsa mahlo a hau, lilense tsa boleng bo holimo li ka thibela mahlaseli a UV le khanya e khanyang. Ho etsa hore likhalase tsa hau li be tsa motho ka mong, re boetse re fana ka logo ea foreimi le likhetho tsa ho etsa li-box tsa ka ntle.

Likhalase tsena tse peli ha li na boleng bo phahameng feela le boqapi, empa hape li sebeletsa merero e mengata ea ts'ebetso. Ntlha ea pele, foreimi e entsoe ka acetate ea boleng bo phahameng, e seng feela e bobebe le e monate, empa hape e na le sebopeho se ntlafetseng, se u fang phihlelo ea ho apara hantle. Taba ea bobeli, mebala e metle le e fapaneng ea foreimi e fesheneng haholoanyane mme e ka amohela litlhoko tsa hau tse fapaneng tse tšoanang. Ntle le moo, re fana ka likhetho tse 'maloa tsa mebala ea lense, e u lumellang ho tsamaisana habonolo le mekhoa e fapaneng ha u ntse u bonts'a botho ba hau.

Ho feta moo, lilense tsa rona li hahiloe ka thepa ea boleng bo holimo e khonang ho hanela mahlaseli a UV le khanya e khanyang, ho sireletsa mahlo a hau kotsing. Ebang ke bakeng sa mesebetsi ea kantle kapa ea letsatsi le letsatsi, e ka u fa pono e hlakileng le e phutholohileng. Ntle le moo, re fana ka logo ea foreime le sebopeho sa lebokose la kantle ho etsa hore likhalase tsa hau li be tsa motho le ho bonahatsa tatso ea hau e ikhethang.

Ka bokhutšoanyane, likhalase tsa rona tsa boleng bo holimo ha se feela tsa boleng bo ikhethang le chebahalo empa hape li na le mesebetsi e fapaneng e sebetsang ho phethahatsa litlhoko tsa hau tse fapaneng. U ka khotsofatsoa ke mokhoa oa feshene kapa ts'ebetso e sebetsang. Rea u amohela ho fumana lihlahisoa tsa rona le ho lumella likhalase tsa rona ho khantša bophelo ba hau!
