Ukukhethwa kwezibuko namuhla kukhulu - amavila kuphela angazithengisi, ku-inthanethi, ezimpambanweni ze-metro ngisho nasesitimela, ungabona amafreyimu ahloniphekile anamalensi "asezingeni eliphezulu" ngemali enengqondo. Kodwa uma ukhuluma ngempilo nobuhle, udinga ukukhumbula ukuthi amahlaya ngamehlo awamukeleki. Isinyathelo sokuqala lapho ukhetha izibuko zekhompyutha kufanele senziwe ku-ophthalmologist, ozohlola umbono wakho futhi akusize ngendlela efanele ukukhetha izibuko.
Imisebenzi yezibuko zekhompyutha
Umsebenzi oyinhloko wezingilazi zekhompiyutha uwukunqanda imisebe ye-electromagnetic enikezwa yinoma yimuphi umqaphi, kungakhathaliseki ukuthi abakhiqizi basithembisa ini. Ukuze wenze lokhu, i-coating ekhethekile isetshenziswa kuma-lens, inani lawo elincike kuhlobo lomsebenzi. Ukuze usebenze ngemibhalo, izithombe ezicacile noma amathoyizi nje, ama-lens aklanyelwe ngokuhlukile, ngakho-ke udinga ukubonisana nochwepheshe.
Ngesikhathi esifanayo, izibuko zekhompiyutha kufanele zivikele amehlo ngangokunokwenzeka ekuphepheni njalo kwesikrini, okomisa i-retina yeso, kuholela ekucasukeni, ebubomvu nasekulunyweni.
Izibuko zokuzivocavoca
Izibuko ezingavamile, lapho amalensi asobala athathelwa indawo yipulasitiki emnyama enezimbobo eziningi ezincane, ahlangatshezwa yiwo wonke umuntu. Ukubuyekezwa mayelana nabo kuhluke kakhulu, into eyodwa icacile - ngeke kube khona ukulimala ekusetshenzisweni kokuqeqeshwa (kubizwa nangokuthi izibuko zokuqondisa). Ukuphumula kwamehlo nokuqeqeshwa kwemisipha yamehlo kuyadingeka kuwo wonke umuntu, ikakhulukazi labo abasebenza kukhompyutha.
Udokotela kuphela okufanele akhethe izibuko zokuqeqesha, uzophinde akutshele isikhathi esihle sokusebenza kulezi zibuko. Kufanele kukhunjulwe ukuthi zingagqokwa kuphela emini enhle noma ukukhanya okufakelwayo okukhanyayo futhi kungabi ngaphezu kwamahora amathathu ngokulandelana ngosuku.
Imithetho yokukhetha amaphoyinti ekhompuyutha
- Umuthi kadokotela ovela kudokotela wamehlo uyisihluthulelo sempilo yamehlo akho, thatha isikhathi sokuya kudokotela. Kubantu abangaboni kahle, njengomthetho, izibuko zekhompiyutha zibhala i-diopter eyodwa noma ezimbili ngaphansi kwezibuko zokugqoka unomphela.
- Udinga ukuthenga izibuko zekhompyutha kuphela kuma-salon akhethekile optical, lapho, ngendlela, kuvame ukuba nochwepheshe abanemishini edingekayo ukuze bahlole umbono wakho.
- Ama-lens ane-coating ekhethekile angakhethwa ngokusekelwe kwisabelomali, kodwa kuyadingeka ukucabangela okubaluleke kakhulu - ukuqhathanisa okukhulayo noma ukuthuthukisa ukukhiqizwa kombala. Amalensi aphezulu kakhulu futhi ahlolwe isikhathi akhiqizwa ochwepheshe abavela eSwitzerland, eJalimane naseJapane, kodwa imikhiqizo yabo i-priori ayikwazi ukushibhile.
- I-eyeglass ifreyimu ingase ingabi yinhle kakhulu (kodwa uma indawo yakho yokusebenza ingeyona ikhompyutha yasekhaya, khona-ke lokhu kubalulekile), kodwa kufanele kube ntofontofo, ingawi futhi ingabangeli ukungakhululeki.
- Inkomba yokukhethwa okulungile kwezibuko kukodwa kuphela-uma usebenza kukhompyutha ezingilazini ezikhethiwe, amehlo awakhathali futhi awalimazi.
Ngokuvamile, lapho ukhetha izibuko ezijwayelekile, banikeza ukwenza i-anti-computer coating ekhethekile kumalensi. Uma isikhathi esichithwa kukhompuyutha sincane, le nketho ifanelekile, kwezinye izimo, udinga ukucabanga ngokuthenga izibuko ezikhethekile. Zinakekele wena namehlo akho, ube nempilo.
