Enye yezinto ezibalulekileyo ekufuneka ziqwalaselwe xa kuthengwa iiglasi zamehlo ezichazwe ngugqirha bubunzima beelensi.Ubunzima beelensi zakho abuchaphazeli nje ukubonakala kweeglasi zakho, kodwa kunye nokuthuthuzela kunye nomsebenzi wabo.Ukuqinisekisa ukuba wenze ukhetho olufanelekileyo, kubalulekile ukuqonda izinto ezichaphazela ubukhulu be-lens yeglasi.
Into yokuqala ekufuneka iqwalaselwe ngamandla kagqirha.Okukhona uphezulu umyalelo wakho, kokukhona uya kufuna iilensi ezityebileyo.Imigqaliselo eyomeleleyo ibandakanya iigophe ezomeleleyo, ezifuna imathiriyeli ethe kratya ukufezekisa ulungiso lombono olwaneleyo.Ukuba unommiselo ophezulu, unokufuna ukuqwalasela iilensi eziphezulu.Ezi lens ziyilelwe ngokukodwa ukuba zibe mfutshane kwaye zibe khaphukhaphu kuneelensi zesintu, zizenza zibe lolona khetho lubalaseleyo kubantu abane-myopia ephezulu.
Enye inkalo emele iqwalaselwe yimathiriyeli yelensi.Izixhobo zelensi ezahlukeneyo zinezalathisi ezahlukeneyo zokuhlaziya, ezichaphazela indlela ukukhanya okugoba ngayo njengoko kudlula kwilensi.Ngokuqhelekileyo, izinto eziphezulu zesalathisi zinesalathisi esiphezulu se-refractive, oku kuthetha ukuba banokugoba ukukhanya ngokufanelekileyo.Ke ngoko, iilensi zesalathiso esiphakamileyo zincinci kuneelensi zeplastiki eziqhelekileyo zamandla afanayo kagqirha.
Ukongeza, ukhetho lwezakhelo luya kuchaphazela nobukhulu beelensi zokubukela.Izakhelo ezingenarim ezigcweleyo zikholisa ukulingana iilensi ezityebileyo, ngelixa iifreyimu ezingenarim okanye ezingenarimless zifuna iilensi ezibhityileyo ukuze zilingane ngcono.Ngoko ukuba ukhetha uhlobo oluthile lwesakhelo, qiniseka ukuba uqwalasela indlela oluchaphazela ngayo ubukhulu beelensi zakho.
Okokugqibela, izixhasi zelensi ezifana neengubo ezichasene ne-reflective zinokuchaphazela ubukhulu beeglasi zakho.Ezi zambatho zinciphisa ukukhanya kunye nokucamngca kwiilensi, ukuphucula induduzo ebonakalayo kunye nokucaca.Nangona zingachaphazeli ngokuthe ngqo ubukhulu be-lens, zinokwenza i-lens ibonakale incinci ngenxa yokunciphisa ukukhanya.
Isishwankathelo, kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha i-lens yeglasi elungileyo.Amandla akho achazwe ngugqirha, imathiriyeli yelensi, ukhetho lwesakhelo, kunye nophuculo lwelensi zonke zidlala indima ekumiseleni ubukhulu belensi.Ngokubonisana nengcali yamehlo, unokwenza isigqibo esinolwazi esingayi kukubonelela kuphela ngowona kulungiswa kombono, kodwa nokuqinisekisa ukuba iiglasi zakho zikhululekile kwaye zinesitayile.
