Tsanangudzo yeDefocus Signal
"Defocus" chiratidzo chakakosha chekuona mhinduro inogona kushandura maitiro ekukura kweziso rinokura. Kana defocus stimulation ikapihwa nekupfeka lenzi panguva yekukura kweziso, ziso rinokura rakananga kunzvimbo ye defocus chiratidzo kuti uwane emmetropia.
Semuyenzaniso, kana concave lenzi yakapfekwa paziso rinokura kuti riise negative defocus (kureva kuti, tarisiro iri kuseri kweretina), kuitira kuti tarisiro iwire paretina, mboni yeziso inokura nekukurumidza, izvo zvinosimudzira. kukura kwe myopia. Kana iyo convex lens yakapfekwa, ziso rinogashira yakanaka defocus, chiyero chekukura cheziso chinodzikira, uye chinokura chakananga ku hyperopia.
Basa reDefocus Signals
Inowanikwa kuti zviratidzo zve defocus yeperipheral retina inoita basa rinokosha pakugadzirisa kukura uye kukura kweziso reziso, kunyanya kana zviratidzo zvepakati nepakati zvepakati zvisingaenderani, zviratidzo zvemukati zvichatonga. Mune mamwe mazwi, iyo peripheral defocus masiginecha ine simba rakakura pane emmetropization regulation kupfuura yepakati defocus state!
Vatsvagiri vanotenda kuti kana wakapfeka magirazi ekuona-imwe chete, iyo yepakati inotariswa inofananidzwa pane retina, asi iyo yeperipheral yakatarisa inofananidzwa kuseri kweretina. Iyo peripheral retina inogamuchira hyperopic defocus chiratidzo, izvo zvinoita kuti axis yeziso ikure uye myopia kudzika.
Dhizaini yemagirazi e defocus
Multi-point micro-transmission defocus magirazi akagadzirwa uye anogadzirwa maererano nemusimboti weperipheral myopia defocus, kuitira kuti mufananidzo weperipheral uwire pamberi pe retina. Panguva ino, ruzivo rwunoendeswa kune mboni yeziso ruchadzikisa kukura kweaxis yeziso. Zvidzidzo zvakasiyana zvakaratidza kuti myopia control effect yakanyatsoenderana nenguva yekupfeka, uye zvinokurudzirwa kuipfeka kweanopfuura maawa gumi nemaviri pazuva.
Tsvagiridzo pachiyero chakakura che optical defocus myopia inoratidza kuti kuona kure-kure kwemifananidzo yeretinal inomhanyisa kukura kweziso, zvichitungamira kurebesa kwemboni yeziso uye kukura kwemyopia. Sezvineiwo, pedyo-kuona-defocus yemifananidzo yeretinal inononoka kukura kweziso. Iyo yekutarisa inowira pamberi pe retina nekuda kwepedyo-inoona defocus inogona kuderedza kukura kweziso asi haigone kupfupisa axial kureba.
Kune vechidiki vane axis yeziso kureba isingadariki 24mm, iyo yakanakira myopic defocus yakasanganiswa kudzivirira uye kudzora matanho anogona kuve akajairwa ziso kureba muhukuru. Nekudaro, kune vanhu vane axis yeziso kureba inopfuura 24mm, kureba kweaxial hakugone kupfupikiswa.
Micro-lens chiedza matanda pamagirazi emaziso anoumba myopic defocus masaini mukati meziso, ayo ari akakosha ekuderedza myopia kukura. Zvisinei, kuvapo kwema micro-lenses pamalenses hazvirevi hazvo kuti zvinobudirira; ma micro-lenses anofanira kutanga ashanda zvinobudirira. Naizvozvo, kugadzira uye kugadzirisa tekinoroji yemamicro-lenses pamalenzi zvakare inoedza hunyanzvi uye tekinoroji yemakambani ekugadzira.
Dhizaini yeMulti-Focus Micro-Lenses
Nekubuda kwe "defocus theory," vagadziri vakuru ve lens vakagadzira mhando dzakasiyana dze defocus lenzi. Mumakore maviri apfuura, ma-multi-focus micro-lens defocus lenses akatangwa zvakare imwe mushure meimwe. Kunyangwe iwo ese ari e-multi-focus defocus lenzi, pane misiyano yakakura mudhizaini uye nenhamba yekutarisa.
1. Kunzwisisa kweMicro-Lenses
Kana wakapfeka magirazi emaziso ekuona kamwe chete, chiedza chinobva kure chinogona kuwira pafovea, nechepakati pe retina. Zvisinei, chiedza chinobva kumativi, mushure mokupfuura nelens imwe chete, hachisviki kune imwe ndege ye retina. Sezvo retina ine curvature, mapikicha anobva kumativi anowira kuseri kweretina. Panguva iyi, uropi hwakachenjera zvikuru. Pakugamuchira iyi kukurudzira, retina inongoerekana yaenda kumufananidzo wechinhu, zvichiita kuti mboni yeziso ikure kumashure, zvichiita kuti dhigirii remyopia rirambe richiwedzera.
Zvakakosha kucherechedza:
1. Retina ine basa rekukura rakananga kumufananidzo.
2. Kana mufananidzo wecornea yepakati ukawira panzvimbo yeretina, nepo mufananidzo weparipheri ukawira kuseri kweretina, unokonzera kure-kuona kure.
Basa rema micro-lenses kushandisa musimboti wekushandura mwenje neakawedzera positive lenzi mumativi ekudhonzera mifananidzo yeperipheral kumberi kweretina. Izvi zvinogonesa kujeka kwepakati pekutarisa uku ichibvumira mifananidzo yeperipheral kuti iwire pamberi pechikamu che retina, ichigadzira traction pane retina yekudzivirira nekudzora zvinangwa.
Zvakakosha kucherechedza:
1. Ingave iri peripheral defocus lens kana multi-focus micro-lens, ivo vose vanokwevera mifananidzo yeperipheral kumberi kwe retina kuti vagadzire peripheral myopic defocus vachichengetedza zvakajeka maonero epakati.
2. Mhedzisiro inosiyana zvichienderana nehuwandu hwe defocus yemifananidzo yeperipheral inowira pamberi pe retina.
2. Dhizaini yeMicro-Concave Lenses
Mukuonekwa kwema-multi-focus micro-defocus lenses, tinogona kuona akawanda micro-defocus points, ayo anoumbwa neamwechete concave lenses. Tichifunga nezvezvino magadzirirwo magadzirirwo, concave lenses inogona kukamurwa kuita: single power spherical lenses, yakaderera isiri-micro-defocus lenses, uye akakwira asiri-micro-defocus lenses (ane mutsauko wakakura musimba pakati pepakati uye periphery).
1. Mhedzisiro yekufungidzira ye-high non-micro-defocus lenses inosangana nezvinotarisirwa, zvichipa nani myopia control.
2. Kusvibiswa kwe "mifananidzo" yakasvibiswa: Malensi epamusoro asina-micro-defocus anogadzira maramu echiedza asingatarise uye anotsauka. Kana chiratidzo chiri pamberi pe retina chakanyanya kujeka, chinogona kusarudzwa sechiratidzo chekutanga chekutarisa pedyo, zvichiita kuti mifananidzo inotevera ione kure-kure.
Zvakanakira kushandisa yakakwirira isiri-micro-defocus lenses:
1. Kugadzira matambudziko ekufungidzira kuhuropi nekusagadzira tarisiro, vana havangatarise kushandisa micro-lenses, asi vachazvimiririra vanosarudza kuisa pfungwa pazvikamu zvakajeka pakati penzvimbo yepakati uye periphery.
2. Kugadzira myopic defocus nehupamhi uye ukobvu, zvichiita kuti kusimba kwakasimba uye kunatsiridza myopia kutonga kushanda.
3. Njodzi dzeKuona neMicro-Concave Lenses
Kunyanya kunetseka ne myopia control lens ane micro-lenses ndeyekuti vana vanogona kutarisa pazvinhu vachishandisa micro-lenses, izvo zvinogona kuva neanotevera mhedzisiro mhedzisiro:
1. Kusarudzwa kwekuona kwepedyo sechiratidzo chikuru chekuona
2. Kusaona zvakanaka kwezvinhu
3. Kupfeka kwenguva refu kunokanganisa kugadzirisa
4. Kutungamira kune zvisizvo zvigadziriso uye convergence matching
5. Kusashanda myopia control paunenge uchiona zvinhu zviri pedyo
Mukupedzisa
Nekuwedzera kwakasiyana-siyana kwe-multi-focus micro-defocus lenses, kusarudza iyo yakarurama inova dambudziko. Pasinei nekugadzirwa kwe lens, chinangwa ndechekugadzira mufananidzo wakajeka pane retina uchichengetedza yakagadzikana uye yakagadzikana myopic defocus chiratidzo pamberi pe retina kuti inonoke kufambira mberi kwe myopia uye ziso axial elongation. Ihwo hunyanzvi, tekinoroji, uye kuvimbiswa kwemhando ye-multi-focus micro-defocus lenses kwakakosha. Malensi asina kunaka haangotadza kudzikamisa kufambira mberi kwemyopia uye axial elongation asi kupfeka kwenguva refu kunogona kukanganisa gadziriso, zvichitungamira mukusangana kusingaite.
