Haufinyane tjena, hangata re bona lihlooho tse ling tse hopotsang hore “likhalala tsa letsatsi li phela lilemo tse peli feela ’me li tlameha ho nkeloa sebaka ka mor’a nako eo.” Joale, na bophelo ba likhalase tsa letsatsi ehlile ke lilemo tse peli feela?
Likhalase tsa letsatsi li hlile lia “tsofala”
Thepa ea motheo ea lense ea likhalase ka boeona e ka monya mahlaseli a mang a ultraviolet, ’me ho khabisoa ha lilense tsa likhalase le hona ho ka bonahatsa a mang a mahlaseli a ultraviolet. Lilense tse ngata tsa likhalase le tsona li na le lisebelisoa tse monyang UV tse kentsoeng ho tsona. Ka tsela ena, mahlaseli a mangata a ultraviolet a ka “bolokoa” ’me a ke ke a hlola a ntša mahlo a rōna kotsi.
Empa tšireletso ena hase ea ka ho sa feleng.
Kaha mahlaseli a ultraviolet a na le matla a mangata, a tla tsofatsa thepa ea likhalase tsa letsatsi le ho fokotsa matla a metsoako e sireletsang letsatsing ho monya mahlaseli a ultraviolet.

Tsena li tla fokotsa matla a tšireletso a UV a likhalase tsa letsatsi.
Ho phaella moo, haeba re sa hlokomele likhalase tsa rona, hangata li tla baka ho roala ka ho toba ha lilense, ho lokoloha ha litempele, ho senyeha, le ho senyeha ha foreimi le liphahlo tsa nko, joalo-joalo, tse tla ama ts'ebeliso e tloaelehileng le phello ea tšireletso ea likhalase tsa letsatsi.
Na ho hlile hoa hlokahala ho e nkela sebaka ka mor'a lilemo tse ling le tse ling tse peli?
Pele ho tsohle, ke batla ho bolela hore sena ha se menyenyetsi, empa lipatlisiso tsena li teng.
Moprofesara Liliane Ventura le sehlopha sa hae sa Univesithi ea Sao Paulo e Brazil ba entse lipatlisiso tse ngata ka likhalase tsa letsatsi. Ho e 'ngoe ea lipampiri tsa bona, ba boletse hore ba khothaletsa ho fetola likhalase tsa letsatsi ka mor'a lilemo tse ling le tse ling tse peli. Qeto ena e boetse e qotsitsoe ke mecha ea litaba e mengata, 'me joale re atisa ho bona litaba tse tšoanang tsa Sechaena.
Empa qeto ena e hlile e na le motheo, ke hore, bafuputsi ba balile ho latela matla a sebetsang a likhalase tsa letsatsi naheng ea Brazil ... , e lokela ho nkeloa sebaka.
Ha re utloeng. Naheng ea Brazil, khanya ea letsatsi e tjena libakeng tse ngata… Ntle le moo, ke naha e chesehang haholo ea Amerika Boroa, 'me karolo e fetang halofo ea naha e sebakeng sa tropike…
Kahoo ho latela pono ena, batho ba karolong e ka leboea ea naha ea heso ha ba khone ho roala likhalase tsa letsatsi ka lihora tse 2 ka letsatsi. Ka hona, re ka boloka chelete e itseng.

Hopola feela tsena ha u khetha likhalase tsa letsatsi
Ha e le hantle, ho hang ha ho thata ho khetha likhalase tsa letsatsi tse tšoanelehang. U hloka feela ho batla likhalase tsa letsatsi tse nang le logo ea "UV400" kapa "UV100%" lebenkeleng le tloaelehileng.Matšoao ana a mabeli a bontša hore likhalase tsa letsatsi li ka fumana tšireletso e ka bang 100% khahlanong le mahlaseli a ultraviolet. Ho lekane ho ba le phello e sireletsang.
Joang ho khetha 'mala? Ka kakaretso, bakeng sa tšebeliso ea letsatsi le letsatsi, re ka fana ka pele ho lilense tse sootho le tse bohlooho, hobane li na le tšusumetso e fokolang ho 'mala oa lintho, li loketse ho sebelisoa letsatsi le leng le le leng, haholo-holo ho khanna,' me li ke ke tsa ama tlhokomelo ea mokhanni oa mabone a sephethephethe.

Ha u khetha likhalase tsa letsatsi, ho na le tšobotsi e le ’ngoe e hlokomolohuoang habonolo, ’me ke “sebopeho.” Ho bonolo ho nahana hore likhalase tse nang le sebaka se seholoanyane le sekoti se lumellanang le sebopeho sa sefahleho se na le phello e ntle ka ho fetisisa ea tšireletso ea letsatsi.
Haeba boholo ba likhalase tsa letsatsi bo sa tšoanelehe, ho kobeha ha ho lumellane le sebopeho sa sefahleho sa rona, kapa lilense li nyane haholo, leha lilense li na le ts'ireletso e lekaneng ea UV, li ntse li tla lutla leseli hohle hohle, li fokotsa haholo ts'ireletso ea letsatsi.
