Kugwiritsa Ntchito Plexiglass Pazachipatala

Plexiglass imakhalanso ndi ntchito yodabwitsa mu mankhwala, yomwe ndi kupanga ma cornea opangira.Ngati cornea yowonekera ya diso la munthu ili ndi zinthu zosaoneka bwino, kuwala sikungalowe m'diso.Uwu ndi khungu lomwe limayambitsidwa ndi leukoplakia yonse ya cornea, ndipo matendawa sangachiritsidwe ndi mankhwala.

Chifukwa chake, asayansi azachipatala akuganiza zosintha cornea ndi mawanga oyera ndi cornea yokumba.Otchedwa yokumba cornea ndi ntchito mandala zinthu kupanga galasi mzati ndi awiri okha millimeters awiri, ndiye kubowola dzenje laling'ono mu cornea wa diso la munthu, kukonza galasi ndime pa cornea, ndi kuwala. amalowa m'diso kudzera pagalasi.Diso la munthu likhoza kuonanso kuwalako.

Kale mu 1771, katswiri wa ophthalmologist anagwiritsa ntchito galasi la kuwala kupanga galasi lagalasi ndikuyika cornea, koma sizinaphule kanthu.Pambuyo pake, kugwiritsa ntchito kristalo m'malo mwa galasi la kuwala kunalephera kokha patatha theka la chaka.Mu Nkhondo Yachiwiri Yapadziko Lonse, pamene ndege zina zidagwa, chivundikiro cha cockpit chopangidwa ndi plexiglass pa ndegecho chinaphulika, ndipo maso a woyendetsa ndegeyo anali ndi zidutswa za plexiglass.Patapita zaka zambiri, ngakhale kuti tiziduswa timeneti sitinatulutsidwe, sizinapangitse kutupa kapena mavuto ena m’maso mwa munthu.Izi zidachitika kuti ziwonetse kuti plexiglass ndi minofu yamunthu imagwirizana bwino.Nthawi yomweyo, idalimbikitsanso akatswiri a maso kuti apange ma cornea opangira ma plexiglass.Lili ndi kufalitsa kwabwino kwa kuwala, kukhazikika kwa mankhwala, sikuli ndi poizoni kwa thupi la munthu, kuphweka mosavuta mu mawonekedwe omwe akufuna, ndipo kungakhale kogwirizana ndi maso aumunthu kwa nthawi yaitali.Makornea opangidwa ndi plexiglass akhala akugwiritsidwa ntchito kwambiri kuchipatala.
