Ibirahuri.
Mu minsi ya mbere yo gukosora iyerekwa, indorerwamo z'amaso zose zakozwe mu kirahure.
Ibikoresho nyamukuru byikirahure ni ikirahure cyiza.Indangantego yo kwisubiraho irarenze iy'ibikoresho bya resin, bityo ibirahuri by'ibirahure biroroshye kuruta ibyuma bya resin mu mbaraga zimwe.Igipimo cyo kuvunika ibirahuri ni 1.523, 1.60, 1.70, 1.80, 1.90.Ibirahuri by'ibirahure bifite uburyo bwiza bwo kohereza no gukanika imashini: icyerekezo gihoraho cyangirika kandi gihamye kumubiri na chimique.
Nubwo ibirahuri bitanga optique idasanzwe, biraremereye kandi birashobora kumeneka byoroshye, bishobora guteza ingaruka mbi kumaso cyangwa no kubura ijisho.Kubera izo mpamvu, ibirahuri by'ibirahure ntibikoreshwa cyane mu ndorerwamo z'amaso.

Ibikoresho bya plastiki.
50 1.50 CR-39
Mu 1947, uruganda rwa Armorlite Lens muri Kaliforuniya rwashyizeho lens ya mbere yoroheje ya plasitike y'amaso.Lens yari ikozwe muri polymer ya plastike yitwa CR-39, mu magambo ahinnye yiswe “Columbia Resin 39,” kubera ko yari inshuro ya 39 yakozwe na plastiki ikize yumuriro yakozwe na PPG Industries mu ntangiriro ya 1940.
Kubera uburemere bwacyo bworoshye (hafi kimwe cya kabiri cyuburemere bwikirahure), igiciro gito kandi cyiza cyiza cya optique, plastike CR-39 ikomeje kuba ibikoresho bizwi cyane mumirasire yijisho ndetse nubu.
● 1.56 NK-55
Igiciro cyinshi cyane murwego rwohejuru rwa lens kandi birakomeye cyane ugereranije na CR39.Nkuko ibi bikoresho bigera kuri 15% byoroshye kandi 20% byoroshye kurenza 1.5 bitanga amahitamo yubukungu kubarwayi bakeneye linzira yoroheje.NK-55 ifite Abbe agaciro ka 42 bigatuma ihitamo neza kubitabo hagati ya -2.50 na +2.50 dioptres.
Lens Inzira ndende ya plastike
Mu myaka 20 ishize, mu rwego rwo gusubiza icyifuzo cy’amadarubindi yoroheje kandi yoroheje, abakora lens benshi batangije lensike ya plastike yo hejuru.Izi lens ziroroshye 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 cyane, agaciro ka Abbe, uburemere buke bwihariye hamwe n’ingaruka zikomeye.
MR ™ Urukurikirane rukwiranye cyane cyane nubuvuzi bwamaso kandi bizwi nkibintu bya mbere bya thiourethane shingiro ryibikoresho byo hejuru.MR ™ urukurikirane rutanga ibicuruzwa bitandukanye kugirango bitange igisubizo cyiza kubakoresha optique.
RI 1.60: MR-8
Ibyiza biringaniye byerekana indangagaciro 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 lens ibikoresho.Ibikoresho byiza bya lens yoroheje kandi irwanya ingaruka zikomeye.MR-7 ifite ubushobozi bwo gusiga amabara meza.
RI 1.74: MR-174
Ultra high index lens ibikoresho bya ultra thin lens.Abambara lens ikomeye cyane ubu bafite ubudahangarwa kandi buremereye.

Inzira ya Polyakarubone.
Polyakarubone yatunganijwe mu myaka ya za 70 kugira ngo ikoreshwe mu kirere, kuri ubu irakoreshwa mu kureba ingofero y’ingendo zo mu kirere ndetse no mu kirahure cyo mu kirere.Indorerwamo z'amaso zikoze muri polyakarubone zatangijwe mu ntangiriro ya za 1980 hagamijwe gukenera linzira zoroheje, zidashobora guhangana n'ingaruka.
Kuva icyo gihe, lensike ya polyakarubone yabaye ihame ryibirahure byumutekano, indorerwamo za siporo n’imyenda y'abana.Kuberako bidashoboka kuvunika kuruta lensike isanzwe ya plastike, lens ya polyakarubone nayo ni ihitamo ryiza ryimyenda y'amaso idafite aho ihurira n'ibice bigize ikadiri hamwe na dring.
Ibindi bikoresho byinshi bya pulasitiki bikozwe muburyo bwo kubumba, aho ibintu bya pulasitiki byamazi bitetse mugihe kirekire muburyo bwa lens, bigakomera plastike yamazi kugirango ikore lens.Ariko polyakarubone ni thermoplastique itangira nkibikoresho bikomeye muburyo bwa pellet nto.Mubikorwa byo gukora lens byitwa inshinge, pellet zirashyuha kugeza zishonge.Amazi ya polyakarubone noneho yinjizwa byihuse mububiko bwa lens, agabanywa kumuvuduko mwinshi hanyuma akonjeshwa kugirango akore lens yarangije muminota mike.

Inzira ya Trivex.
Nubwo ifite ibyiza byinshi, polyakarubone ntabwo aribikoresho byonyine byifashishwa mu gukoresha umutekano ndetse n’imyenda y’abana.
Mu 2001, PPG Industries (Pittsburgh, Penn.) Yerekanye ibikoresho bya lens bahanganye byitwa Trivex.Kimwe na lisansi ya polyakarubone, lens ikozwe muri Trivex iroroshye, yoroheje kandi irwanya ingaruka cyane kuruta plastike isanzwe cyangwa ibirahuri.
Lens ya Trivex, ariko, igizwe na monomer ishingiye kuri urethane kandi ikozwe muburyo bwo gushushanya bisa nuburyo lensike isanzwe ikorwa.PPG ivuga ko ibi biha lens ya Trivex ibyiza bya optique ya optique kuruta inshinge za polikarubone zatewe inshinge.
