Tlhaloso e Khutšoanyane:

flat top bifocal ke e 'ngoe ea lilense tse bonolo ka ho fetisisa tsa multifocal ho ikamahanya le tsona, ke e 'ngoe ea lilense tse tsebahalang haholo lefatšeng.Ho “tloha” ka tsela e ikhethang ho tloha bohole ho ea haufi le pono ho fa ba roetseng libaka tse peli tse khethiloeng hantle tsa likhalase tsa bona hore ba li sebelise, ho latela mosebetsi o etsoang.Mohala o hlakile hobane phetoho ea matla e teng hang-hang ka monyetla oa ho u fa sebaka se pharaletseng sa ho bala ntle le ho sheba hole haholo ho theosa le lense.Hape ho bonolo ho ruta motho ho sebelisa bifocal ka hore o sebelisa bokaholimo bakeng sa sebaka se hole le tlase ho bala.

Likarolo tsa Sehlahisoa

1) Melemo ea Lilense tsa Bifocal

Li-presbyopes tse ling li khetha lilense tse ngata tse tsoelang pele, tse fetolang matla butle-butle ho tloha karolong e ka holimo ho ea tlaase ho lense, ntle le mela ea ho li arola.Leha ho le joalo, li-bifocals tse tloaelehileng li fana ka monyetla o itseng ho feta lilense tse tsoelang pele, joalo ka ho fana ka lilense tse pharaletseng bakeng sa mosebetsi oa komporo le ho bala ha ho bapisoa le lilense tse tsoelang pele.Li-bifocal tsa morero o khethehileng li fumaneha hape bakeng sa mosebetsi oa khomphutha le mesebetsi e meng e hlokang pono e matla e haufi le e mahareng.
Le hoja li-bifocals li sebetsa hantle haholo bakeng sa mesebetsi e kang ho khanna le ho bala, li na le moeli oa bokhoni ba tsona ba ho fana ka pono e hlakileng lintlheng tse lipakeng, tse kang sebaka sa ho hlahloba k'homphieutha.
Ha ho bapisoa le lense e tsoelang pele, melemo ea li-bifocals ke hore lia tšepahala 'me hangata li theko e tlase ho feta lilense tse tsoelang pele.

2) Likarolo tsa Lense ea CR39:

① Ho sebelisa CR39 monomer e nang le boleng bo tsitsitseng le bokhoni bo bongata ba tlhahiso.e fumaneha hape ka tlhahiso ea lense ea monomer CR39 ea lapeng, lihlahisoa tse amoheloang Amerika Boroa le Asia, hape li fana ka ts'ebeletso ea HMC le HC.
②CR39 ha e le hantle e betere ho feta Polycarbonate, E rata ho tint, 'me e ts'oara lesela hantle ho feta lisebelisoa tse ling tsa lense.
③Lihlahisoa tsa rona tsa CR39 li kenyelletsa lense e pota-potileng, e bataletseng, lense e tsoelang pele, lense e tšoeu e felletseng le lense ea Lenticular.sephara, tšesaane, leseli, phetiso e phahameng, 'mala o tsitsitseng, le moralo o nepahetseng, le tsona li fana ka lense e felileng.
④Ka theko ea tlholisano le boleng bo botle bo tsitsitseng, Aogang Optical e lula e batla tšebelisano ea nako e telele ea khoebo.
⑤Ke lisebelisoa tse ntle haholo bakeng sa likhalase tsa letsatsi le likhalase tsa ngaka.
