Abanye abantu bacinga "ukuphazamiseka" ngeengozi zeekhompyutheni yinkqubo yokuthengisa yabathengisi bale miqathango yokukhusela (iiglasi zegumbi zekhompyutha). Ukuze siqonde ukuba ziyimfuneko, siya kutshintshi yolwazi lwenzululwazi.
Kutheni sifuna iiglasi zecomputer, zinceda?
- Ikhompyuter kwikhompyutheni ibonisa ukukhanya kwimiba ebomvu ibomvu, i.e. yonke indawo. Kodwa umthwalo omkhulu kunamehlo ane-violet kunye ne-blue-wave-ray ray, kufuphi ne-ultraviolet radiation. Amandla okubhubhisa loo mijelo kunye nomsebenzi onzulu kwikhompyutheni ibangela izifo ezahlukahlukeneyo zamehlo.
- Kuboniswe ukuba le mijelo emfutshane yomsindo ihlakazekile kwaye ikhutshwe endleleni. Ngoko ke, phantse ungangeni kwindawo ephambili ye-retina, eyangena emlilweni oluhlaza kunye nolwaphuzi (i-long wave). Ngenxa yoko, umlingo umfanekiso ulahlekelwa icace.
- Ngokutsho kophando lwe-Academician Fedorov, indawo ebomvu yembonakalo ikhuthaza ukukhawuleza kweenkqubo zokuxilisa, ukubuyiswa kweeseli zamathambo esiso. Wena. le mibala ayinayo impembelelo.
Ngaloo ndlela, ukuba uyasusa kwi-esweni kweso esangweni eliyingozi kunye nemibala ebomvu, ungayikhupha umthwalo onzima emehlweni kwaye unciphise inani lokutshatyalaliswa kokukhanya, okuya kukwandisa ukucaca komfanekiso.
Ngako oko, iziglasi zekhompyutheni zikhusela kwaye ziphumelela ngokwenene. Kodwa kuphela ukukhusela ukuphazamiseka kwe-electromagnetic, njengokuba abanye abathengisi abanamaqhinga abaqinisekisileyo, kodwa ukuba bathuthele ngokukhethekileyo umbala webala.
Ngoko, ngenxa yoluhlu olukhethiweyo lokupenda kwimilo yecala, ezi zilandelayo zifezekiswe:
- ukuxutywa kwemisebe ye-ultraviolet eyingozi;
- ukuhanjiswa kwerhafu ebomvu-orange kwi-spectrum efanelekileyo emehlweni;
- Ukwandisa umbala;
- ukunciphisa ukubonakala kokukhanya kweso siqendu, i-glare;
- ukubonelela ngokubhekiselele komfanekiso obonakalayo.
Ngenxa yoko, amathuba okwehlo kweziliso ayancipha, ukunyuka komntu wonke kunciphisa, kwaye ukunyuka kwamandla okusebenza (malunga nama-30%).
Ungakhetha njani iiglasi zekhompyutha?
Xa ukhetha iiglasi zekhompyutheni, kufuneka uqale u tyelele i-ophthalmologist. Emva koko, akuzona zonke ezo zinto, kwaye ke kuyimfuneko ukuqwalasela umboniso womntu othile. Ziziphi iiglasi zekhompyutheni ezingcono kuwe, zinokumisela kwii-salons ze-optics, apho kuthethwa khona ukubonisana kwe-oculist.
Iziglasi zekhompyutheni zingaba kunye okanye ngaphandle kwe-diopters. Kuyakwazi ukudibanisa iilazi kunye neenlense zoqhagamshelwano ngaphandle kobunzima obongezelelweyo kwamehlo.
Iilensi zeglasi zekhompyutheni zizo zezi ntlobo:
- monofocal;
- bifocal;
- variofocal;
- i-trifocal;
- inkqubela phambili (multifocal).
Kukhona iiglasi zekhompyutheni yee-degrees ezahlukeneyo ze-dimming. Unokwakhetha nayiphi na ifreyimu ehambelana nobuso bakho.
Ukongeza kwamathuba okufaka izicelo
Kwizibuko ezinjalo zikhululekile kumagumbi adibeneyo, ngokukodwa ngokukhanyisa izibane. Kwakhona, iiglasi zekhompyutheni zingasetyenziswa ngaphandle kwimozulu efufayo kwaye ilanga. Ngoko ke, banokuthiwa yiyo yonke indawo, abafanelekile ukugqoka ngokusisigxina. Akukho ziphikisana nazo, nazo ziyacetyiswa kubantwana ngelixa zichitha ixesha kwikompyutha.
