Ngaba loluphi uhlobo lweelensi eziqhubela phambili i-lens ye-stitoocal ye-stitocal?

Okokuqala, yintoni i-lens ye-stitofocal ye-stifocal?
Ngaphezulu kwe-1, ukugxila ngokuthe ngcembe iilensi kwilensi enye kuphela phakathi kokukhanya kwaye kuphantse ngaphandle kokufumana ukufundwa kakuhle kwaye kuphantse ukuphelelwa yi-organic, ke kwi-A Ilensi kwangaxeshanye sijonge umgama, umgama ophakathi kwaye uvale umlomo ofunekayo.

Iilensi ezihambelanayo zineendawo ezintathu ezisebenzayo
Indawo yokuqala yokusebenza yeyokusebenza kwindawo ekude ibekwe phezulu kwilensi. Indawo yomgama linani lamanani afunekayo ukubona kude, isetyenziselwe ukubona izinto ezikude.
Indawo yesibini yokusebenza yindawo yokubonisa ibekwe kumda ongezantsi welensi. Ukusondela linani lamanani afunekayo ukubona izinto ezikufutshane.
Indawo yesithathu yindawo ephakathi edibanisa ezimbini. Ibizwa ngokuba yindawo yeGradient, ngokuthe ngcembe itshintsha inqanaba lokujonga kude kwinqanaba lokujonga kufutshane, ukuze ungayisebenzisa ukubona izinto kumgama ophakathi. Ngenkangeleko, iilensi ze-stitofis ezihambelanayo ziyanyanzeleka kwiilensi rhoqo.

Zimbini, zeziphi iintlobo zelensi ye -usus (
Kwiminyaka yakutshanje, iilensi ze-stifocials ze-stifocials ze-stifocal inkqubela phambili ziye zaphuhliswa kwaye zidume ngokukhawuleza eChina. Okwangoku, ngokwendlela yokusebenzisa iliso kunye nezomzimba zabantu abakwiminyaka eyahlukeneyo, kulu phando oluhambelana neelensi ezigxile kwiilensi ezininzi lunokwahlulwa zangamacandelo amathathu:
1 Isetyenziselwa ukunciphisa ukudinwa okubonakalayo kunye nokulawula ukuphuculwa kweMyopia.
I-2. Anti-snatiue iilensi zabantu abadala. Isetyenziselwa abantu abaninzi abasebenza kumgama omalunga nokunciphisa ukutyeba okubonakalayo okubangelwa ngumsebenzi.
I-3. Iilensi ezihambelanayo kubantu abadala nabadala. Iiglasi zeglasi zabantu abalupheleyo nabalupheleyo zinokuzibona ngokulula kwaye zikufuphi, ukuze amehlo akho afumane imvakalelo yobutsha.

Zintathu, yintoni umsebenzi weelensi ye -usus (
.
QAPHELA: Kungenxa yokuba uninzi lwezigulana ezine-myopia zinengxaki yangaphandle endaweni yokuxakeka, inani labantu abalungele ukulawula ii-mypia zinqongophele, ezichaza i-10% kuphela ne-myopia.
(2) Ootitshala, ogqirha, umgama osondeleyo kwaye abantu abaninzi besebenzisa iikhompyuter, ukuze banciphise iikhompyuter ezibonakalayo eziziswe ngumsebenzi.
Kubantu abaneminyaka emihlanu nabadala kunye neeglasi zeglasi ukuze babone ukuba babone kakhulu. I-lens ye-stitoocal eqhushumba yenzelwe ukubonelela ngendlela yendalo, efanelekileyo nefanelekileyo kwizigulana zePortgoopia ukuba zilungiswe. Ukunxiba ilensi eqhubekayo ifana nokusebenzisa ikhamera yevidiyo. Iiglasi zeglasi zinokubona izinto ezikude, kufutshane ne-Pivemaight. Ke ngoko, sichaza iilensi eziqhubayo njenge "iilensi ezisondeza", kwaye zinxibe iiglasi ezilingana nokuhlawula ngaphezulu kweglasi.

Okwesine, yintoni endifanele ndinikele ingqalelo xa ndinxibe i-lenses ye-stitoocal ye-stiocal?
(1) Xa ukhetha isakhelo se-piripi, ubungakanani besizakhelo singqongqo. Kuyimfuneko ukukhetha isakhelo sesakhelo esifanelekileyo kunye nokuphakama ngokomgama womfundi.
. Ngeli xesha, kufuneka uguqule intloko yakho kancinci kwaye uzame ukubona embindini weelensi, kwaye ukungonwabi kuya kunyamalala.
