The Generation of Stress in Eyeglasses
Tichifunga nezve kushushikana kwe lens, isu tinoziva kuti kukanganisa kwekushushikana pane ega ega zvigadzirwa zvelens idiki, uye inogona kutonzi haina kukosha.Naizvozvo, muyero yenyika yemalenses muChina, kushushikana ma paramita haabatanidzwe mumaitiro ekufanirwa.Saka, chii chinokonzera kushushikana kwegirazi remaziso?Izvi zvinonyanya kuenderana nehunyanzvi hwekuita tekinoroji yekugadzirira girazi remaziso.
Muzvitoro zvezvitoro zvegirazi remaziso, panguva yekuisa lenzi yepasi mufuremu, chiremba wemaziso anogaya lenzi yakati kurei kupfuura saizi chaiyo inodiwa kudzivirira lenzi kuti risanyanya kusununguka uye kuvharika zviri nyore kubva pafuremu.Izvi zvinoita kuti pave nekuchengetedza kwakachengeteka kana lenzi yakasungirirwa pafuremu ine screws, ichidzivirira kuti isatsvedza.Nekudaro, oparesheni iyi inogona kuwedzera kushushikana kwe lens, zvichitungamira mukusagadzikana kana yapfekwa.Yakawandisa lens zviyero kana kuwedzeredza-kuomesa kwefuremu screws zvinogona kukonzera kusaenzana kufananidzwa pamusoro peiyo lens, zvichikonzera mafungu-senge mafungu uye kukanganisa kunaka kwekufungidzira.
Iyo Phenomenon yeEyeglass Stress Generation
1. Birefringence
Nekuda kwekukura kudiki kwekukuya kwelens, kuomesa panguva yekusangana kunoita kuti nzvimbo yeperipheral yelens idzvinyirwe, zvichikonzera kuwedzera kuwanda.Shanduko yedensity iyi inoshandura iyo yekutanga refractive index ye lens, zvichikonzera kuitika kwe "birefringence" mulenzi.
2. Skewed
Kuparadzira Panguva yekusangana kwegirazi remaziso, kana saizi yakanyanya kusimba, zvinokonzeresa kuti lenzi idzvinyirwe, zvichikonzera "makwinya" epamusoro uye zvichikonzera kupararira kwe lens.
Kana takatarisana nenyaya dzakadai, tinogona kubvisa lens kubva pafuremu kuti tichinje iyo yakamanikidzwa mamiriro eiyo lens.Iyi shanduko ndeyekugadziriswa kwekunetseka kwechinguva, uye mushure mekunge simba rekunze rabviswa, mamiriro e lens anogona kusunungurwa kana kudzoreredzwa zvachose.Zvisinei, zvakakosha kucherechedza kuti kana kune kushanduka kwemukati kwenguva refu kunokonzerwa nekumanikidzwa kwekunze, kunyange kana lens yakaparadzaniswa uye yakasanganiswa, haigoni kuvimbisa kudzorerwa kwe lens kune yayo yepakutanga.Muchiitiko ichi, sarudzo chete ndeyokusarudza kugadzirisa lens itsva.
Kushushikana kweLens kunowanzoitika mumagirazi akazara-furemu, uye mumagirazi asina rimless, zvinogonawo kuitika kana rimu waya yakanyanya kusimba.Rudzi urwu rwechiitiko chinowanzoitika munzvimbo yeperipheral ye lens, uye kushushikana kudiki kune kakukanganisa pamhando yekuona uye haisi kuoneka nyore.Zvisinei, kana kushushikana kwakanyanyisa, kunokanganisa nzvimbo yepakati yemaziso, zvichiita kuti usaonekwe uye kuneta kwekuona, kunyanya kana uchitarisa kumativi kana panguva yekuongorora mafambiro.
Nekuti kushushikana kwegirazi remaziso kunonyanya kukonzerwa nekutsikirirwa kwefuremu, magirazi asina furemu anoratidza kuita zvirinani kuzorodza kushushikana.
Eyeglass Stress Self-test Method
Mushure mekuiswa pasi pemasimba ekunze, ma lens ezvigadzirwa zvakasiyana anoburitsa maitiro akasiyana ekushushikana nekuda kwekusiyana kwehuremu, kuoma, uye chimiro chemukati.Nekudaro, zviitiko zvekushushikana zvinogona kuitika zvisinei nechinhu.Izvi zvinotevera sumo pfupi kune nzira yekuedza kushushikana.Zvishandiso zvinodiwa imonitor yekombuta uye polarized lenzi.
Operating method:
1. Tanga kombiyuta uye uvhure gwaro reShoko risina chinhu.(Kuyedza kushushikana kunoda kushandiswa kwechiedza chepolarized, uye komputa yekutarisa ndiyo yakajairika sosi yekuyedza kushushikana chiedza.)
2. Isa magirazi pamberi pekombuta uye nyatso tarisa kuti uone kana pane abnormal phenomena iripo.
3. Shandisa polarized lenses (zvisarudzo zvinosanganisira magirazi ezuva, polarized lens clips, uye 3D movie magirazi) kutarisa maitiro ekunetseka pamalenzi emagirazi uye kombiyuta yekuongorora.
Polarized lenses inogona kuratidza kukanganiswa kwemavara munzvimbo yeperipheral ye lens, inova kuratidzwa kwemaitiro ekushushikana.Kugoverwa kwekunetseka pamagirazi kunowanzoonekwa sezvipingamupinyi zvinoshungurudza uye minda yekushungurudzika, uye dhigirii yemaitiro ekushungurudzika yakanyatsobatana nekushungurudzika kwemaitiro emagirazi.Nekuongorora kugoverwa kwemaitiro ekudzvinyirira, tinogona kuona zviri nyore kutungamira kwekumanikidza uye kuwanda kwekunetseka uko lens yakaitika panguva yegungano.
Pakuongororwa, lens yepakutanga isati yasangana ichine imwe dhigirii yekushushikana mukusavapo kwemasimba ekunze.Izvi zvinokonzerwa nemasimba asina kuenzana akadai sekumanikidza uye shrinkage panguva yekugadzira, zvichikonzera kushushikana kwemukati.Zvakakosha kucherechedza kuti kuvapo kwekunetseka kwemukati mumagirazi emaziso kwakaoma kudzivisa, uye zvishoma kana zvishoma zvemaitiro ekushungurudzika zvinogamuchirwa.Panguva imwecheteyo, maitiro ekudzvinyirira haafaniri kugoverwa kune optical centre ye lens kuti arege kukanganisa maitiro ekuona.
Mukupedzisa
Izvo zvinokonzeresa zvemagirazi emaziso zvinogona kuve nemhedzisiro pamhando yavo yekuona, senge kusagadzikana pakupfeka uye kupararira munzvimbo yekuona yeperipheral.Zvisinei, tinofanira kuziva kuti kushushikana mupfungwa kwemagirazi emaziso kwakaoma kudzivisa, uye chero bedzi kuri mukati memwero wakafanira, tapuro yokuona inogona kuva isingakoshi.Malenses akagadziridzwa anobatsirwa kubva kune lathe tekinoroji, zvichikonzera kuderera kwemamiriro ekushushikana, uye zvino zvave chigadzirwa chakanyanya mumusika wepamusoro-wekupedzisira maziso.
