Amalensi aqhubekayo efomu yamahhala aya ngokuya ethandwa kakhuluizingubo zamehlonamuhla ngenxa yokusebenza kwazo okuthuthukisiwe kokubukwa kanye nekhono lazo lokwenza kube ngokwakho kunoma ubani ozigqokile.

Ayini Amalensi Amahhala Amafomu Aqhubekayo?

Amalensi efomu yamahhala awuhlobo oludume kakhulu lwamalensi encazelo ephezulu futhi enziwa ubuchwepheshe befomu lamahhala elingakuvumela ukuthi uzuze ama-optics angcono.Nasi isiqhathaniso samalensi amafomu ajwayelekile namahhala:

Amalensi ajwayelekile:

Amalensi ajwayelekile aqala njengelensi emiswe ngaphambili eqedwe kancane esevele inomklamo oqhubekayo obunjwe endaweni engaphambili.Kulebhu yokukhiqiza, incwadi kadokotela izokhiqizwa ngemuva kwelensi futhi isikhunta asishintshiwe.

Amalensi efomu lamahhala:

Amalensi efomu amahhala enziwa ngedijithali kusetshenziswa isofthiwe ebala incwadi kadokotela kanye nezinye izici eziningi ezifana nokutsheka kwe-pantoscopic kanye nendawo yokufaka ifreyimu.Lokhu kuzivumela ukuthi zenziwe ngendlela oyifisayo esigulini ngasinye, kunokusebenzisa ilensi eyakhiwe ngaphambili.

Ubuchwepheshe befomu lamahhala buyakwazi ukubeka amalensi angaphezulu kumandla akhuphukayo we-.01 diopeter, okuvumela ukunemba kubhangqa ngalinye kuyo yonke incwadi kadokotela ehlukile.Odokotela bamehlo banquma ngezikhawu ezingu-.25 ze-diopter futhi iso lomuntu linganquma kuphela ukuthi lincane kangakanani izikhawu ezingu-.15 ze-diopter.Nakuba lokhu kungase kubonakale kungenamsebenzi, kufanele kuqashelwe ukuthi lokhu kunemba kuyindawo enkulu yokuthengisa yabaningi abafuna ukuthenga amalensi amafomu mahhala.

Yiziphi Izinzuzo Zamahhala Amalensi Athuthukayo?

Kunezizathu eziningi zokuthi kungani abantu bakhetha amalensi aqhubekayo efomu lamahhala.Nazi izinzuzo ezimbalwa kweziningi ezinikezwa ngamalensi aqhubekayo wamahhala:

Ukwenza kube ngokwakho:

Ilensi ngayinye iyakwazi ukwenziwa ngokwezifiso kuzo zonke iziyalezo ezihlukile.Ungathola ozimele bemfashini ezindaweni ezifana naleziI-Rx-Ukuphephafuthi usebenzise ubuchwepheshe befomu lamahhala ukuze uhambisane nencwadi yakho kadokotela.

Ukucaca okubonakalayo okuthuthukisiwe:

Ubuchwepheshe befomu lamahhala bukhuphule ukusebenza okubonakalayo kumalensi awo, okukuvumela ukuthi ubone kangcono kunangaphambili nakuwo wonke amabanga.

Faka zonke izinhlobo zemithi kadokotela:

Amalensi aqhubekayo efomu lamahhala ayakwazi ukuthwala zonke izinhlobo zemiyalelo ehlukene, okuhlanganisa nemiyalelo enamandla.Lokhu kwenza ukugqoka ama-no-line lens aqhubekayo kube lula kakhulu.

Okubukeka kukhanga ngokwengeziwe:

Ngenxa yokuthi ubuchwepheshe befomu lamahhala buyakwazi ukuthwala ngisho nemiyalelo engajwayelekile, abaklami abaningi bamalensi benze okwengeziwe.izitayela zozimele.

Ubani Okufanele Athenge Amalensi Amahhala Amafomu Aqhubekayo?

Kube nokukhula okukhulu kwenani labantu abacela amalensi aqhubekayo efomu lamahhala futhi angaba yisinqumo esihle kwabaningi.Uma unencwadi kadokotela engavamile, ufuna ukwandisa ukucaca kwakho okubonakalayo, noma awujabulile ngamalensi akho aqhubekayo ajwayelekile, kungaba umqondo omuhle ukucabangela ukunikeza.ifomu khulula lens okuqhubekayoukuzama.
