Iiglasi zezemidlalo ziyingxenye ebalulekileyo yoluhlu lwabantu bonke abakhokelela kwimpilo enempilo. Abavelisi baphucula umzekelo ngamnye kunyaka, basebenzisa izinto ezininzi zanamhlanje kunye nezizinzileyo, ukuphucula iilensi, ukudala izinto ezintle ezicocekileyo kunye nezobugcisa. Njengokuba kukho konke, kubalulekile ukukhetha imodeli efanelekileyo wena kunye nemidlalo yakho.
Iindidi zemiglasi yezemidlalo
Iiglasi zezemidlalo zelanga-ezikhuselayo-zenza umnyama omnye okanye enye. Kukho imizekelo emininzi yezemidlalo ngaphakathi kwesi sixeko (iiglasi zezemidlalo zokuqhuba, ukuhamba ngebhayisekile, ukunyuka nokunye okunjalo) kunye nezikhethekileyo zokuzonwabisa kwiimeko ezizodwa. Ngokomzekelo, ukuhamba kwiintaba okanye entlango, iilazi ezinesidumbu esinamandla zifunekayo. Eli pharamitha luchaza ukukhanya okukhanya kunye nokuhamba okulula kwe-lens. Umgca wokugqibela uvame ukuboniswa kwisitika esikhethekileyo, iinqonga okanye ilebula. Kukho iintlobo ezintlanu:
- 0 - phantse i-lens okanye i-lenses engabonakali, ephantse idlule ilanga;
- 1 - ukususela kuma-43 ukuya kuma-80% - ukukhanya okukhanya;
- 2 - ukuthunyelwa kokukhanya kulingana no-18 ukuya kuma-43% - izinga eliphakathi;
- 3 - ilanga lingena kwi-8 - 18% kuphela;
- Ii-lens ezingekho-transmissive ii-4 ezingaphantsi kwe-8%.
Umbala wemibala
Le parameter ayikho ukubonakaliswa kwesinambatho kunye nesitayela, kodwa into echazwe yimiqathango yangaphandle kunye neemeko:
- Ukuze ufunde i-tennis, khetha iiglasi zezemidlalo nge-blue or lens. Baya kuphucula ulwahlulo lwekrele eliphuzi ngokubhekiselele kwimvelaphi yentsimi.
- Kulo galufa, ulungele ukulungelelanisa iilensi zethusi - ezi ziza kunika ubunzulu bomfanekiso kwaye uncede ukubona ibhola elimhlophe likhanyise.
- Kwakhona, uluhlu lwama-amber lucetyiswa kubaqhubi beebhayisiki kunye nabazingeli. Isiglasi sokubhinqa kwiilazi zezemidlalo ezinjalo kuya kunciphisa ukukhanya okukhanya. Ngokubanzi, uhla oluphuzi luhle kwiimeko eziphantsi zokukhanya (ubusika, inkungu, amafu).
- Xa ukuqhuba imidlalo yamanzi epholile iilensi nazo zifanelekile - umsebenzi wazo oyintloko kukugxininisa i-glare kuboniswa ngamanzi.
- Okuthandwayo ngamanani amaninzi asemagqabini kuye kwafumanisa ukubaluleka kungekhona nje ngokuba iilensi zemibala zinika ubuninzi bokukhanya. Bayekezela kuphela ukukhanya okukhazimulayo, ngaphandle kokuphazamisa umbala wokubona.
- Abafaki bemidlalo yasebusika, njengomthetho, bakhethe izilwanyana zama-glass kunye neilensi ezibomvu okanye ezimnyama. Ukubona ngcono ikhephu eligubungelekileyo kwiimozulu zezulu, khetha amathoni e-orange, kunye nosuku olukhanyayo lwelanga, iiglasi zezemidlalo ezibalaseleyo zibomvu. Ukunciphisa inani lokukhanya eliboniswa kwikhephu liza kusiza isibuko sokubhinqa.
- Kwaye, ekugqibeleni, izibuko zesikrini eziqhelekileyo, intandokazi yabaninzi, zinako ukunciphisa igalelo lelanga elikhanyayo emehlweni ethu. Bandisa ukwahlula komfanekiso, banike ithuba lokuvuyela ngokupheleleyo indawo.
Izibuko zemibala yezemidlalo kunye ne-diopters . Nangona konke ukuphuhliswa kwetheknoloji yanamhlanje, iilazi zezemidlalo ezikhoyo azikwazi ukwenza ngokupheleleyo umsebenzi wokulungisa amehlo. Inyaniso kukuba ezininzi iimpawu zemiSebenzi yangaphandle zenziwa nge-lens ephihliweyo, kwaye ukuveliswa kwezinto zokuhamba ngokusebenza kusetyenziswa ngokubanzi kunye neendawo "eziplatiweyo". Ukongezelela, ukulungiswa okubonakalayo kunye ne-curvature enkulu akuyona into ekhethekileyo, kuba umfanekiso ophosakeleyo unokuthi uwandise iingxaki zombono, zibangele i-prismatic effect kunye ne- astigmatism .
Izixhobo zemiglasi yezemidlalo
Okubaluleka ngokubalulekileyo yizinto ezivela kulo mzekelo. Bafanele babe namandla kangangoko, kodwa bavule. Uphuhliso lwakamuva - iimveliso ze-carbon fibre, ezinamaxesha angama-10 anamandla kwaye ngexesha elifanayo 75% lilula ngaphezu kwesimbi. Ukuzama nokukhetha iiglasi zakho, qaphela ukuhamba kwawo. Iiglasi zemigangatho zithempelesi eziguquguqukayo, kukuvumela ukuba ukhethe ukulungiswa okugqibeleleyo, kuxhomekeke kubukhulu kunye nokuma kwentloko. Enye enye inqaku - umlomo uyayeka. Ngethuba lokusebenza kunye nokuphefumula okuninzi, akufanele bahlabe, badonsa okanye baphazamise. Abantu abaninzi banokuthenga ngokukhawuleza iiglasi zezemidlalo kwi-band elastic - zigqithwe njengesiqhelo, kodwa kwimeko ethile kulula, efanelekileyo kwaye, ngokubalulekayo, ngokubalulekayo, egcinwe ngokukhuselekileyo entloko.
