Ma waho aʻe o ka lilo ʻana i lens multifocal me nā laina ʻike ʻole ʻia, hiki i nā lens holomua ke ʻike hou i ka poʻe me ka presbyopia e ʻike maopopo i nā mamao āpau.
ʻO nā pono o nā lens holomua ma mua o nā bifocals
ʻElua wale nō mana o nā maka aniani bifocal: hoʻokahi no ka ʻike ʻana i ka lumi a ʻo kekahi no ka ʻike kokoke. ʻO nā mea ma waena, e like me ka pale lolouila a i ʻole nā mea ma ka papa hale kūʻai, hoʻomau pinepine ʻia me nā bifocals.
No ka hoʻāʻo ʻana e ʻike maopopo i nā mea ma kēia ʻāpana "waena", pono nā mea hoʻohana bifocal e hoʻoluli i ko lākou poʻo i luna a i lalo, e nānā pono ana ma luna a ma lalo o kā lākou bifocals, e ʻike ai i kahi ʻāpana o ka lens e ʻoi aku ka maikaʻi.
Hoʻohālikelike nā lens holomua i ka ʻike kūlohelohe āu i hauʻoli ai ma mua o ka hoʻomaka ʻana o ka presbyopia. Ma kahi o ka hāʻawi ʻana i ʻelua mau mana lens e like me bifocals (a ʻekolu paha, e like me nā trifocals), ʻo nā lens holomua he mau "multifocal" ʻoiaʻiʻo e hāʻawi i ka holomua maikaʻi ʻole o nā mana lens he nui no ka ʻike maopopo ma waena o ka lumi, ma kahi kokoke a ma nā mamao a pau. ma waena.
ʻIke kūlohelohe me ka "lele kiʻi" ʻole
ʻO nā laina i ʻike ʻia ma nā bifocals a me nā trifocals he mau kiko kahi i loaʻa ai kahi abrupt. Eia kekahi, ma muli o ka liʻiliʻi o nā mana lens i nā bifocals a me nā trifocals, ua kaupalena ʻia kou hohonu o ka nānā ʻana me kēia mau lens. I mea e ʻike maopopo ʻia, pono nā mea i loko o kahi kikoʻī o nā mamao. ʻO nā mea ma waho o nā mamao i uhi ʻia e ka mana o ka lens bifocal a i ʻole trifocal e pohihihi a hoʻololi i ka mana lens.
ʻO nā lens holomua, ma ka ʻaoʻao ʻē aʻe, loaʻa ka holomua ʻole o nā mana lens no ka ʻike maopopo ma nā mamao āpau. Hāʻawi nā lens holomua i kahi hohonu kūlohelohe o ka nānā ʻana me ka ʻole "lele kiʻi."
Hoʻololi liʻiliʻi ka mana o nā lens holomua mai kahi a kahi kiko ma ka ʻili o ka lens, e hāʻawi ana i ka mana leki kūpono no ka ʻike pono ʻana i nā mea ma kahi mamao.
Hāʻawi ia i ka ʻike maopopo ma nā mamao āpau (ma mua o ʻelua a ʻekolu paha mau mamao ʻike ʻokoʻa).
No ka ʻike maikaʻi, hōʻoluʻolu a me ke ʻano, hiki iā ʻoe ke koho i nā alaloa ākea no ka maʻalahi a me ka wikiwiki o ka hoʻololi ʻana ma mua o nā lens holomua holomua. Hiki iā ʻoe ke neʻe i ka ʻaoʻaohttps://www.universeoptical.com/wideview-product/e nānā i nā kikoʻī hou aku e pili ana i kā mākou mau hoʻolālā holomua hou.
