Ibirahuri.
Mubihe byambere byo gukosora iyerekwa, indorerwamo zose zamaso zakozwe mubirahure.
Ibikoresho nyamukuru byikirahure ni ikirahure cya optique.Indangantego yo kwangirika irarenze iy'ibikoresho bya resin, bityo ibirahuri by'ibirahure biroroshye kuruta ibyuma bya resin mu mbaraga zimwe.Igipimo cyo kugabanya ibirahuri ni 1.523, 1.60, 1.70, 1.80, 1.90.Ibirahuri by'ibirahure bifite itumanaho ryiza hamwe nubukanishi bwa mashini: guhora wunvikana kandi bigahoraho kumubiri na chimique.
Nubwo ibirahuri bitanga optique idasanzwe, biraremereye kandi birashobora kumeneka byoroshye, bishobora guteza ingaruka zikomeye kumaso cyangwa no kubura ijisho.Kubera izo mpamvu, ibirahuri by'ibirahure ntibikoreshwa cyane mubirahuri by'amaso.

Ibikoresho bya plastiki.
50 1.50 CR-39
Mu 1947, uruganda rwa Armorlite Lens muri Kaliforuniya rwatangije lens ya mbere ya plastike yoroheje.Lens yari ikozwe muri polymer ya plastike yitwa CR-39, mu magambo ahinnye yiswe “Columbia Resin 39,” kubera ko yari inshuro ya 39 ya plastiki ikize yumuriro yakozwe na PPG Industries mu ntangiriro ya 1940.
Kubera uburemere bwayo bworoshye (hafi kimwe cya kabiri cyuburemere bwikirahure), igiciro gito kandi cyiza cya optique, CR-39 plastike ikomeza kuba ibintu bizwi cyane kumaso yindorerwamo.
● 1.56 NK-55
Ibihendutse cyane murwego rwohejuru kandi biragoye cyane ugereranije na CR39.Nkuko ibi bikoresho byoroheje 15% kandi byoroheje 20% kurenza 1.5 itanga amahitamo yubukungu kubarwayi bakeneye lensike yoroheje.NK-55 ifite Abbe agaciro ka 42 bigatuma ihitamo neza kubitabo hagati ya -2.50 na +2.50.
Lens Indanganturo ndende ya plastike
Mu myaka 20 ishize, mu rwego rwo gusubiza icyifuzo cy’amadarubindi yoroheje, yoroheje, abakora ama lens benshi bashyizeho lensike ya plastike yo hejuru.Izi lens zoroshye kandi zoroshye kurusha CR-39 ya plastike kuko ifite urwego rwo hejuru rwo kugabanuka kandi rushobora no kugira uburemere buke bwihariye.
MR ™ Urukurikirane ni optique ya optique yateguwe nu Buyapani Mitsui Chemical ifite indangagaciro yo kwangirika, agaciro ka Abbe, uburemere buke bwihariye hamwe n’ingaruka zikomeye.
MR ™ Urukurikirane rukwiranye cyane nubuvuzi bwamaso kandi bizwi nkibintu bya mbere bya thiourethane ishingiro ryibikoresho byo hejuru.MR ™ urukurikirane rutanga ibicuruzwa bitandukanye kugirango bitange igisubizo cyiza kubakoresha optique.
RI 1.60: MR-8
Ibyiza biringaniza indangagaciro yibikoresho hamwe nigice kinini cyisoko rya RI 1.60.MR-8 ikwiranye n'imbaraga zose z'amaso kandi ni igipimo gishya mubikoresho by'amaso.
RI 1.67: MR-7
Isi yose RI 1.67.Ibikoresho byiza bya linzira yoroheje kandi irwanya ingaruka zikomeye.MR-7 ifite ubushobozi bwiza bwo gusiga amabara.
RI 1.74: MR-174
Ultra ndende yerekana ibikoresho bya ultra thin lens.Abambara lens ikomeye cyane ubu bafite ubudahangarwa kandi buremereye.

Inzira ya Polyakarubone.
Polyakarubone yatunganijwe mu myaka ya za 70 ikoreshwa mu kirere, kandi kuri ubu irakoreshwa mu kureba ingofero y’indege ndetse no mu kirere cyogajuru.Indorerwamo z'amaso zikoze muri polyikarubone zatangijwe mu ntangiriro ya za 1980 hagamijwe gukenera lisansi yoroheje, irwanya ingaruka.
Kuva icyo gihe, lensike ya polyakarubone yabaye ihame ryibirahure byumutekano, indorerwamo za siporo hamwe n ijisho ryabana.Kuberako bidakunze kuvunika kuruta ibyuma bya pulasitiki bisanzwe, lens ya polyakarubone nayo ni ihitamo ryiza ryimyenda y'amaso idafite aho ihurira n'ibice bigize ikadiri.
Ibindi bikoresho byinshi bya plastiki bikozwe muburyo bwo kubumba, aho ibintu bya pulasitike byamazi bitetse mugihe kirekire muburyo bwa lens, bigakomera plastike yamazi kugirango ikore lens.Ariko polyakarubone ni thermoplastique itangira nkibikoresho bikomeye muburyo bwa pellet nto.Muburyo bwo gukora lens byitwa inshinge, pellet zirashyuha kugeza zishonge.Amazi ya polikarubone noneho yinjizwa byihuse mumashanyarazi, akandamizwa numuvuduko mwinshi hanyuma akonjeshwa kugirango akore lens yarangije muminota mike.

Inzira ya Trivex.
Nubwo ifite ibyiza byinshi, polyakarubone ntabwo aribikoresho byonyine byifashishwa mubikorwa byumutekano hamwe nijisho ryabana.
Muri 2001, PPG Industries (Pittsburgh, Penn.) Yashyizeho ibikoresho bihanganye byitwa Trivex.Kimwe na lisansi ya polyakarubone, lens ikozwe muri Trivex iroroshye, yoroheje kandi irwanya ingaruka kuruta plastiki isanzwe cyangwa ibirahuri.
Lens ya Trivex, igizwe na monomer ishingiye kuri urethane kandi ikozwe muburyo bwo gushushanya bisa nuburyo busanzwe bwa plastike.PPG ivuga ko ibi biha lensike ya Trivex ibyiza bya optique kuruta inshinge za polikarubone.
