Abanye abantu bacabangela "izinto ezimbi" mayelana nezingozi zamakhompiyutha ngenkambo yokuhweba yabahlinzeki balezi zinyathelo zokuphepha (izibuko zamakhompyutha). Ukuze siqonde ukuthi ziyadingeka yini, siphendukela kudatha eqinisekisiwe yesayensi.
Kungani sidinga izibuko zekhompyutha, ziyabasiza?
- Isikrini sekhompyutheni sikhipha ukukhanya ebangeni kusukela ebubende kuya obomvu, isb. wonke umthamo. Kodwa umthwalo omkhulu kakhulu wamehlo unemibala ye-violet ne-blue blue-wave, eduze kwemisebe ye-ultraviolet. Amandla okubhubhisa emisebe enjalo enomsebenzi obanzi ekhompyutheni iholela ezifweni ezihlukahlukene zamehlo.
- Kubonakala ukuthi le mibala emifushane emigqagqabha ihlakazekile futhi igxeka endleleni. Ngakho-ke, cishe ungangeni emgodini we-retina, ongena emisebeni eluhlaza nokuphuzi (i-wave long). Ngenxa yalokho, isithombe sokuqapha silahlekelwa ukucaca.
- Ngokomcwaningi we-Academician Fedorov, indawo ebomvu ye-spectrum igqugquzela ukusheshisa kwezinqubo zokuxuba umzimba, ukubuyiselwa kwamangqamuzana wezicubu zeso. Yebo. le mibala ayinayo umphumela omubi.
Ngakho-ke, uma ususa kumqapha kusuka ekuqapha i-violet eyingozi nemisebe eluhlaza okwesibhakabhaka, ungayilahla umthwalo osindayo emehlweni futhi unciphise inani lokuhlakazeka okukhanya, okuzokwandisa ukucaca kwesithombe.
Ngakho-ke, izibuko zamakhompyutha ezivikelayo ziyasiza futhi ziyasebenza ngempela. Kodwa kuphela ukuvikela ukuphazamiseka kwamandla kagesi, njengabathengisi abathile abangenangqondo abaqinisekisile, kodwa ngokudlulisela okukhethiwe kombala obala obala.
Ngakho-ke, ngenxa yokwakhiwa okhethekile kwezingubo zama-lens zalezi zibuko, okulandelayo kufezwa:
- ukumiswa kwemisebe ye-ultraviolet eyingozi;
- ukudluliselwa kwengxenye ebomvu-orange ye-spectrum ehle emehlweni;
- Yandisa ngombala;
- ukunciphisa ukukhanya okubonakalayo kokuqapha, i-glare;
- ukunikeza ukungafani okungcono kwesithombe esibonakalayo.
Ngenxa yalokho, amathuba okuthi izifo zamehlo ziyancipha, ukukhathala jikelele kuyancipha, futhi ukusebenza komthamo kuyanda (cishe 30%).
Ungakhetha kanjani izibuko zekhompyutha?
Uma ukhetha izibuko zekhompyutha, kufanele uvakashele i-ophthalmologist kuqala. Phela, akuzona zonke ezifanayo, futhi lapha kuyadingeka ukuba ucabangele umbono womuntu othize. Yiziphi izibuko zamakhompiyutha ezingcono kuwe, zinganquma emasiloni ama-optics, lapho kuxoxwa khona ukubonisana kwe-oculist.
Izibuko zekhompyutha zingaba noma zingenayo i-diopters. Kungenzeka ukuhlanganisa izibuko nama contact lens ngaphandle kokunyuka okwengeziwe emehlweni.
Amalensi wezingilazi zamakhompiyutha afana nalezi zinhlobo:
- i-monofocal;
- i-bifocal;
- variofocal;
- i-trifocal;
- okuqhubekayo (multifocal).
Kukhona izibuko zekhompyutheni yezindiza ezihlukene ze-dimming. Ungase futhi uthathe noma yikuphi uhlaka oluhambisana nobuso bakho.
Amathuba angeziwe okufaka isicelo
Ezingilazi ezinjalo zikhululekile emakamelweni avuliwe, ikakhulukazi ngezibani ze-fluorescent. Futhi, izibuko zekhompyutha zingasetshenziswa ngaphandle ngaphandle kwesimo sezulu esibhakabhakeni nesinezulu. Ngakho-ke, zingabizwa ngokuthi zonke izinto, ezifanele ukugqoke unomphela. Akunakho ukuphikisana nabo, futhi banconywa izingane ngenkathi bechitha isikhathi kukhompyutha.
