Malenzi evamwe vanhu anotaridzika ebhuruu, mamwe epepuru, uye mamwe egirinhi. Uye magirazi ekuvharisa chiedza chebhuruu anondikurudzira ane yellowish. Saka nei malenzi ekuvharisa mwenje webhuruu achishanduka yero?
Mukutaura, mwenje chena ine mavara manomwe echiedza, ese akakosha. Chiedza chebhuruu chikamu chakakosha chechiedza chinooneka, uye zvisikwa pachazvo hazvina mwenje muchena wakasiyana. Chiedza chebhuruu chinosanganiswa nechiedza chegirinhi uye cheyero kuratidza chiedza chichena. Chiedza chegirini uye chiedza cheyero chine simba shoma uye hachinyanyi kushatisa maziso, nepo chiedza chebhuruu chine marefu marefu uye simba rakakwirira, iro rinonyanya kushatirisa maziso.
Kubva pakuona kweruvara, iyo anti-blue light lens inoratidza imwe ruvara, uye iyo yakadzika kutaura ndeyeyero. Naizvozvo, kana iyo lens isina ruvara ichishambadzira kuti inogona kuramba mwenje webhuruu, rinotova benzi. Nekuti kusefa mwenje weblue zvinoreva kuti spectrum inogamuchirwa nemeso haina kukwana kana ichienzaniswa neakasikwa spectrum, saka pachave nechromatic aberration, uye huwandu hwechromatic aberration hunoenderana nemaonero emunhu wega wega uye kunaka kwelenzi pachayo.
Saka, kusviba kwelenzi kuri nani here? Kutaura zvazviri, hazvisizvo. Malenzi akajeka kana akasviba eyero haagone kuvharira mwenje webhuruu, nepo lenzi reyero rakajeka rinogona kudzivirira mwenje webhuruu pasina kukanganisa nzira yakajairika. Iyi pfungwa inogona kuregererwa nyore nyore neshamwari dzakawanda pakutenga magirazi emagetsi e-anti-blue. Chimbofungidzira, kana kupfuura 90% yechiedza chebhuruu yakavharwa, zvinoreva kuti iwe haugone kuona mwenje chena, saka unogona kusiyanisa kana yakanaka kana yakaipa kumaziso?
Hunhu hwelens hunoenderana nerefractive index, dispersion coefficient, uye zvidimbu zvemabasa akasiyana. Iyo yakakwira iyo refractive index, iyo yakaonda lens, iyo yakakwirira kupararira, kujeka kwekuona, uye zvidimbu zvakasiyana zvakanyanya anti-ultraviolet, anti-blue mwenje wemagetsi skrini, anti-static, guruva, nezvimwe.
Nyanzvi dzinotaura izvi: “Mwaranzi yechiedza chebhuruu chiedza chine simba guru chinooneka chine urefu hwe400-500 nanometers, chinova chiedza chine simba zvikuru muchiedza chinooneka. Chiedza chebhuruu chine simba guru chinokuvadza maziso zvakapetwa ka10 pane chiedzawo zvacho.” Izvi zvinoratidza simba rechiedza chebhuruu. Yakakura sei! Mushure mekudzidza nezve njodzi yechiedza chebhuruu, mupepeti akaendawo kunopfeka magirazi e-anti-blue light, saka magirazi emupepeti akashandukawo yero!
