Abafowunelwa ukuLawula ukuKhuselwa kunye noLwazi lweMbala
Xa abaninzi abantu bacinga malunga nama-lens, bacinga ngabo njengezixhobo ezisetyenziselwa ukuphucula umbono wazo. Kodwa ii-lens zoqhagamshelwano zisetyenziselwa ukulungiswa kwamabono: ngamanye amaxesha udibanisa iilensi ezisetyenziselwa ukuphathwa okanye ukulawula izifo zamehlo kunye nezifo. Oogqirha bahlala bebhekisela kula ma-lens njengezonxibelelwano zokusetyenziswa kwezonyango. Ezi iilensi ezikhethekileyo zifanelwe ngendlela efana ne-standard lens, kodwa zihlala zenziwe ngezinto ezahlukeneyo.
Izindlela ezimbini oogqirha abasebenzisa iilensi zokunxibelelana zibandakanya ukulawulwa kokuthintela isisu kunye nokuphuculwa kobunqongophala bombala.
Abafowunelwa kunye ne-Epileptic Seizures
Ukuqonda ukukhanya kungabangela ingxaki ebantwini abantu abanesifo sokuhluthwa . Ukukhanya okukhanyayo kungabangela uxhalaba olukhulu xa umntu esengozini yokuxhamla, kwaye izilwanyana eziqhelekileyo azisoloko zinceda kwaye zinokuba nzima ukugqoka ngaphakathi.
Kodwa izifundo zibonise ukuba iilensi zokudibanisa eziluhlaza zincinci zinganceda ukunciphisa i-photoparoxysmal okanye ifoto yesigxina ekuphenduleni izigulane ezinesifo. Impendulo ye-photoparoxysmal ichaza umsebenzi ogqithisileyo wengqondo ovelisa impendulo ekuvuseleleni ukukhanya, ukukhanyisa ukukhanya, okanye izibane zokubamba izibangela. Iilensi zeBlue zibonakala zisebenza ngakumbi kuneminye imibala. Inkampani ye-ophthalm ebizwa ngokuba nguZeiss ivelisa i-lens ebizwa nge-Z1 esebenza kakhulu ekunciphiseni impendulo.
Iingcali zenzululwazi ziphanda ngokuchanekileyo ukuba luhlobo luni lwe-wavelength kufuneka luvalwe ukunciphisa le ntlobo yeempendulo ezingavamile. Kwisifundo esithile, ubunzima obuneminyaka emibili ubudala obunzima bokuthwaxwa kwamanzi kunye nokuxhwaba buya kuba neentlungu ezinjenge-muscle contractions kunye ne-crackks kunye nokunyuka kwesandla. Iingcali zenzululwazi zazama ii-lens ezihlukahlukeneyo kwaye zafumanisa ukuba ezinye iilensi ezicatshulwayo zivalile ukukhutshwa ezininzi.
Iingcaphephe zabo zibonisa ukuba iiseli ezithile kwi-retina zinokuvinjelwa ukunciphisa ukuwa.
Abafownelwa kunye noLwazi lweMbala
Iilensi zokudibanisa ziye zaboniswa ukunceda abantu abaneemfama zobumfama . Nangona ububala bobuqhetseba obunqabile, abantu abaninzi banenkcenkcesha yebala. Ngobunqongophala bombala, imibala eyahlukileyo iyafunyanwa kodwa ididekile.
Ngowe-1974, kwafumaniswa ukuba i-lens ebomvu okanye i-magenta enemibala efakwe kwijiso elingabonakaliyo liya kuhlala liphucula ukuhlukana kombala kwimibono yombono. Enye yeelensi ezidumileyo kule hlobo yengxaki yile lensi ye-X-Chrome, itysi ebomvu, enobumba obunzima obunobunzima obunxibe kwijiso elingabonakaliyo elibonakala liphucula umbala wemibala ebomvu.
I-Marietta Vision yinkampani ephuhlisa inkqubo ye-lromaGen lens. Le nkqubo ye-lens yokudibanisa inikezela ngamanani amaninzi kunye nee-hues ezahlukeneyo kunye noxinzelelo oluvumela ugqirha ukuba akhethe ityiti ethile engenza ngcono kubantu abathile. Iilensi zinokugqithwa ngenye okanye zombini amehlo, kwaye amatshini afumaneka kumagenta, pink, violet, yellow, aqua, i-orange kunye eluhlaza. Ngo-2001, abaphandi bahlolisise le nkqubo kwizigulane ezili-14 ezingenambala.
Iilensi azange zinciphise kakhulu iimpazamo zokubona umbala kodwa zenze ukuba ezo zigulane zive ukuba ziye zaphucula umbala wokujonga umgangatho ophantsi kunye nomsebenzi ophuculweyo kwimisebenzi yemihla ngemihla efuna umbala wokubona.
Kubalulekile ukubonisa ukuba ezi iilensi azibuyiseli ngombono ogqityiweyo wombala nangayiphi na indlela kodwa kunokuba zivumele abantu ukuba bahlule imibala esekelwe eminye imibala ekhanyayo kunye nombala kunokuba kubekho ukucwaswa kombala okwenyaniso. Ngelixa ezi zi gulane zikwazi ukuhlula imibala ababengenayo ingxaki, ngamanye amaxesha iilensi zakha iingxaki ezintsha kunye nezinye iibini zombala.
