Likhalase tsa letsatsi tsa bana ke likhalase tse etselitsoeng bana ka ho khetheha 'me li etselitsoe ho fana ka tšireletso e nepahetseng ea mahlo. Mahlo a bana a senyeha habonolo ho feta a batho ba baholo, kahoo ho na le tlhokahalo e khōloanyane ea likhalase tsa letsatsi tse sebetsang hantle ho itšireletsa khahlanong le mahlaseli a UV le tšenyo ea letsatsi. Likhalase tsa letsatsi tsa bana ba rona li amohela moralo o moholo oa foreimi, o seng fesheneng feela empa hape o sireletsa likhalase tsa bana hamolemo, ho ba lumella ho thabela pono e sireletsehileng le e phutholohileng nakong ea mesebetsi ea kantle.

1. Bana ba hloka likhalase tsa letsatsi ho feta batho ba baholo
Mahlo a bana a lemoha mahlaseli a UV le mahlaseli a letsatsi haholoanyane, 'me lilense tse ka likhalaseng tsa bona li monya mahlaseli a fokolang a UV ho feta a batho ba baholo. Ka hona, bana ba hloka likhalase tsa letsatsi tse sebetsang hantle ho sireletsa mahlo a bona. Likhalase tsa letsatsi tsa bana ba rona li fana ka tšireletso e ntle ka ho fetisisa ea UV le letsatsi e le hore ngoana oa hau a ka bapala ka ntle ka kholiseho.

2. Moralo oa foreimi e fetang boholo
Likhalase tsa letsatsi tsa bana ba rona li nka moralo o moholo oa foreimi, o se nang maikutlo a feshene feela empa hape o sireletsa likhalase tsa bana hamolemo. Moqapi o joalo o ka koahela ka ho feletseng sebaka se potolohileng mahlo, oa fokotsa ho kena ha mahlaseli a ultraviolet le mahlaseli a letsatsi, 'me oa eketsa tšireletso ea mahlo a bana. Ebang ke lipapali tsa ka ntle kapa tšebeliso ea letsatsi le letsatsi, likhalase tsa rona tsa letsatsi li ka fa bana tšireletso e pota-potileng.

3. Lilense li na le tšireletso ea UV400
Likhalase tsa letsatsi tsa bana ba rona li na le lilense tse sirelelitsoeng tsa UV400. Theknoloji ea UV400 e ka thibela ka katleho ho feta 99% ea mahlaseli a kotsi le ho sireletsa mahlo tšenyo ea mahlaseli a kotsi. Boemo bona bo phahameng ba tšireletso bo ka thusa ho thibela mathata a bophelo bo botle ba mahlo a kang cataract, vitreous opacities, le tse ling. Etsa hore bana ba hau ba natefeloe ke pono e phetseng hantle le e hlakileng ka boitšepo ka likhalase tsa letsatsi tsa bana ba rona.
