Uchungechunge lokulwa nokukhathala nokunciphisa umthwalo
Ingabe ngezinye izikhathi uzizwa uluma, ukuvutha noma ukuqina emehlweni akho?
Ingabe uzwa ubuhlungu bekhanda ngemva kokusebenza isikhathi eside?
Ngemva kokusebenza ngamehlo akho eduze isikhathi eside,
uzizwa ufiphele lapho ubheka izinto?
Umklamo we-aspheric longitudinal uyamukelwa, futhi indawo yokusebenza isethelwe ukunciphisa ukukhathala kwamehlo lapho ubheka eduze isikhathi eside.
Idizayini engajwayelekile y elwa nokukhathala ikwenza kukhululeke kakhudlwana ukugqoka!
Uma lokhu kuwukukhathala nje okubonakalayo, yini okufanele siyenze?
Uma kuqhathaniswa namalensi okubona ajwayelekile y, isizukulwane sesibiliama-lens anti-ukukhathala angagcina amehlo akho esebenza futhi alwe nokukhathala okubukwayo.
Ungakwazi ukugcina umsebenzi omuhle wokubuka ngaso sonke isikhathi futhi wenze amehlo akho azizwe ekhululekile
Anti-ukukhathala, yehlisa umthwalo ngo-75°
Ukuze kuxazululwe ukuphazamiseka okubangelwa ukukhathala okubukwayo okuhlala ezimpilweni zabantu, kwavela amalensi eresin elwa nokukhathala.Ucwaningo lwakwamanye amazwe lubonise ukuthi lapho amehlo egxile ekuhlosweni okugxilile, ukulungiswa kwamehlo akugxili ngokuqhubekayo, kodwa ezingeni elithile.Dlidliza phakathi kobubanzi.Njengekhamera egxile ngokuzenzakalela, lezi zinguquko zibizwa ngokuthi ukulungisa ama-micro-vibrations, angezwakali futhi angakwazi ukulawulwa wona ngokwawo.Lesi isimo esijwayelekile samehlo.Njengoba kuboniswe kuMfanekiso A, lapho amehlo ezizwa ekhathele, lokhu kudlidliza okuncane kokulungiswa Ukudlidliza kuzonyamalala ngokwengxenye, okusho ukuthi ikhono lokulungisa lamehlo linzima ukuligcina.Uma ukulungiswa kudlulele, i-amplitude ye-micro-vibration incane kakhulu, futhi amehlo asesimweni se-asthenopia, njengoba kuboniswe kuMfanekiso B. Uma wengeza i-pair of anti-ukukhathala emehlweni ngalesi sikhathi. lens, lungisa micro vibration izoboniswa ngokushesha.Njengoba kuboniswe ku-Figure C, uma kuqhathaniswa no-C no-B, ungabona ushintsho oluphawulekayo ku-amplitude, okubonisa ukuthi ngemva kokugqoka ama-lens aphikisana nokukhathala, amehlo alulame ngezinga elithile, futhi ukukhathala okubukwayo kuye kwathuthukiswa kakhulu.
Phawula: Ngamalensi afanayo e-pairof, ucezu lwe-ifone ludinga ukwenziwa ngendlela oyifisayo, kuyanconywa ukuthi kusetshenziswe amalensi enziwe ngokwezifiso kuzo zonke izinhlangothi ukuze kuqinisekiswe ukunethezeka nobuhle.

● Ukushintsha kokukhanya okwengeziwe okuhlukile kanye nedizayini ye-aspheric ethuthukisiwe inikeza ukubona okunethezeka eduze ngenkathi ilungisa ukubona.
● Vimbela futhi wehlise ijubane ukuvela kwe-asthenopia uma usebenzisa amehlo eduze;
