Litaba - Mekhoa ea tlhokomelo ea likhalase tsa letsatsi\nKamora ho reka likhalase tsa mahlo, ke ka seoelo ba elang hloko tlhokomelo ea likhalase tsa mahlo. Mohlomong batho ba bang ba nahana hore ke e roala feela hlabula lena, 'me batho ba bangata ba nahana hore ba reka likhalase tsa mahlo feela ho itšireletsa khahlanong le mahlaseli a li-ultraviolet le feshene. Ha e le likhalase tse ling tsa letsatsi, ba ke ke ba li nahana. Ebile, haeba likhalase tsa mahlo tsa mahlo hangata li lahloa, mme ts'ebetso ea eona e tla fokola ha nako e ntse e tsamaea. Eseng feela hore e ke ke ea khona ho hanela mahlaseli a kotsi, hape e ka baka mathata a bophelo bo botle ba mahlo a hau.\nTlhokomelo ea likhalase tsa mahlo e batla e tšoana le likhalase tse tloaelehileng. Joale ha re shebeng hore na re ka hlokomela likhalase tsa letsatsi joang.\n1. Haeba lense e na le mabala, mafura kapa likhatiso tsa menoana, sebelisa lesela le bonolo la k'hothone ka har'a likhalase tse khethehileng tsa likhalase ho hlakola lerōle kapa litšila lense.
