Ukufakwa kwelensi eqhubekayo bekulokhu kuyindaba eshisayo embonini yamehlo.Isizathu sokuthi kungani i-lens eqhubekayo ihluke ku-lens eyodwa yokukhanya ukuthi i-lens eqhubekayo ingaxazulula inkinga yabantu abadala bangabona ngokucacile kusukela kude, phakathi nendawo naseduze, okuyinto elula kakhulu, enhle futhi engakwazi ukuhlanganisa iminyaka.Ngakho-ke kungani umkhiqizo "ongcono kakhulu" onjalo unezinga lokungena lika-1.4% kuphela e-China, kodwa ngaphezu kwe-48% emazweni athuthukile?Ingabe kungenxa yenani?Ngokusobala akunjalo, i-xiaobian ikholelwa ukuthi izinga lokuphumelela lokuqhathanisa okuqhubekayo lihlobene eduze.
Izinga lokuphumelela lokufakwa okuqhubekayo lithonywa izici eziningi, njengokulindela kwekhasimende, ihaba lomkhiqizo, ukunemba kwedatha (incwadi ye-optometry, ibanga lomfundi, ukuphakama komfundi, i-ADD, ukukhetha kweshaneli), ukukhetha kwefreyimu ye-lens, njll. Odokotela abaningi bamehlo emsebenzini wabo bayokwenza lokho. kunzima nokukhethwa kwesiteshi.Namuhla, u-Xiaobian uzokwabelana nawe ukuthi ungasikhetha kanjani isiteshi esiqhubekayo.
Ngemva kokubonisana nolunye ulwazi nokubuza odokotela bamehlo abanolwazi, bonke bavumelana ngokuthi akufanele sichaze ukuthi hlobo luni lwesiteshi esifanele amakhasimende kuphela “ngobude bohlaka”, kodwa kudingeka sicabangele izici ezilandelayo:
1. Iminyaka yekhasimende
Ngokuvamile, abantu abaneminyaka ephakathi kanye nabadala abangaphansi kweminyaka engama-55 bangakhetha kokubili iziteshi ezinde nezifushane, ngoba i-ADD ayinkulu kakhulu, futhi ukuzivumelanisa nezimo nakho kulungile.Uma i-ADD ingaphezu kuka +2.00, kungcono ukhethe isiteshi eside.
2. Zijwayeze ukufunda ukuma
Amakhasimende agqoka izibuko ukuze abone izinto, uma ejwayele ukunyakaza kwamehlo, engajwayele ukunyakaza kwekhanda, kunconywa ukuthi iziteshi ezinde nezifushane zingaba.Uma ujwayele ukuhambisa ikhanda, ungasetshenziselwa ukuhambisa amehlo, kunconywa ukuba ukhethe isiteshi esifushane.
3. Ukuvumelana nezimo kwamakhasimende
Uma ukuzivumelanisa nezimo kunamandla, iziteshi ezinde nezifushane zingaba.Uma ukuzivumelanisa nezimo kukubi, kutuswa ukuba ukhethe isiteshi esifushane
4. ENGEZA inombolo ye-photometric (ADD)
ENGEZA phakathi kuka-+2.00d, zombili iziteshi ezinde nezifushane zamukelekile;Uma i-ADD ingaphezu kuka + 2.00d, khetha isiteshi eside
5. Ubude bomugqa oqondile wohlaka
Khetha isiteshi esifushane samafreyimu amancane (28-32mm) kanye nesiteshi eside samafreyimu amakhulu (32-35mm).Akunconywa ukukhetha ozimele abanomugqa omile obude phakathi kuka-26mm noma ngaphezulu kuka-38mm, ikakhulukazi uma amafreyimu anosayizi omkhulu ekhethelwa amashaneli amafushane, ukuze kugwenywe ukungakhululeki nezikhalazo.
6. Ukwehla kwamehlo
Lapho sikhetha iziteshi, kufanele futhi sicabangele ukwehla kwamehlo ekhasimende nezinye izinkinga.Ngokwethiyori, uma ikhasimende likhula, ukwehla kuzoba buthaka, futhi usayizi wedigri yakamuva yokungeza i-ADD uyakhula ngokukhula kweminyaka.
Ngakho-ke, ngisho noma amakhasimende asebekhulile ene-ADD ephezulu, kodwa amandla okunciphisa amehlo atholakala enganele noma awahlali ngokwanele ngemva kokuhlolwa, izimpawu zokungakwazi ukufinyelela endaweni ephumelelayo eseduze nokukhanya nokubona ukufiphala okuseduze kungase. kwenzeka uma bekhetha isiteshi eside noma isiteshi esijwayelekile.Kulokhu, kunconywa futhi ukukhetha isiteshi esifushane.
