Blended bifocals
ʻOiai ʻo ka hapa nui o nā bifocals he mau laina ʻike ʻia ma ka palena o nā ʻāpana lens, aia kahi bifocal poepoe-seg i hui pū ʻia me ka ʻike liʻiliʻi o ka ʻāpana kokoke ma mua o kona kaikunāne poepoe-seg mau.
Hoʻohui ʻia ka seg kokoke i ka ʻāpana mamao o ka lens i ʻike ʻole ʻia.
Me nā laina ʻike ʻole ʻia, hāʻawi ʻia kahi bifocal seg puni i hui ʻia i kahi hiʻohiʻona ʻōpio ma mua o nā bifocals laina.
Loaʻa i nā lens holomua ʻekolu mau ʻōlelo kuhikuhi i hoʻokahi mau aniani.Hiki iā ʻoe ke hana i kahi hana kokoke (e like me ka heluhelu ʻana i kahi puke), ka hana waena (e like me ka nānā ʻana i kahi pūnaewele ma ke kamepiula), a i ʻole ka nānā mamao (e like me ke kaʻa ʻana) me ka ʻole e hoʻololi i kāu mau aniani.Kapa ʻia lākou i kekahi manawa he mau lens multifocal.
He mea hou nā lens holomua ma nā lens bifocal a me trifocal.ʻO kēia mau ʻano aniani kuʻuna ʻelua i loaʻa nā laina kikoʻī i nā lens.Loaʻa i ka poʻe holomua ke nānā ʻole.I kekahi manawa kapa ʻia lākou he "no-line bifocals," akā ʻaʻole pololei kēlā.ʻOi aku ka pololei o ke kapa ʻana i nā lens holomua "no-line trifocals."
