Nekuwedzera kwemaawa emasikati uye chiedza chezuva chakanyanya, uchifamba mumigwagwa, hazvina kuoma kuona kuti vanhu vazhinji vakapfeka ma lens ephotochromic kupfuura kare. Magirazi ekunyoreswa kwave kuri kukura kwemari muindasitiri yekutengesa eyewear mumakore achangopfuura, uye mafotochromic lenses anoramba ari akasimba ekutengesa kwezhizha. Musika uye kugamuchirwa kwevatengi kwemafotochromic lenses kunobva pamaitiro avo, kudzivirira kwakareruka, uye zvine chekuita nekutyaira.
Mazuva ano, vanhu vakawanda vanoziva kukanganisa kwe ultraviolet mwaranzi inogona kukonzera paganda. Masikirini ezuva, maparasol, kepisi dzebaseball, uye kunyange zvivharo zvemaoko zveaizi zvave zvinhu zvakakosha pakushanya kwechirimo. Kukuvadzwa kwemwaranzi yeUV kumaziso kunogona kusakurumidza kuoneka seganda rakatsvuka, asi nekufamba kwenguva, kufumurwa zvakanyanya kunogona kukonzera mhedzisiro yakanyanya. Zvirwere zvemaziso senge cataract uye zera-ane hukama macular degeneration zvakaratidzwa kuve zvine zvakananga kana zvisina kunanga zvinongedzo kune UV kuratidzwa. Parizvino, vatengi veChinese havana pfungwa yakabatana ye "nguva yekupfeka magirazi ezuva" zvichienderana nemamiriro ezuva. Kazhinji, nzvimbo yekunze yemwenje inotoda kuchengetedzwa kwechiedza, asi vatengi vazhinji vanonzwa kuti "hazvina basa" uye vanosarudza kusapfeka. Kutarisana nemamiriro ezvinhu aya, photochromic lenses, iyo inopa kururamisa kwekuona uye kuchengetedzwa kwechiedza pasina kudiwa kwekubviswa semagirazi ezuva enguva dzose mumamiriro akasiyana, ari kuwana kugamuchirwa pakati pevanhu vakawanda.
Nheyo yekuchinja kwemavara mu photochromic lenses inobva pa "photochromism." Munzvimbo dzekunze, malenzi aya anosviba kuita semagirazi ezuva uye anodzokera kuchena uye pachena mukati memba. Hunhu uhwu hunobatanidzwa nechinhu chinonzi silver halide. Munguva yekugadzira, vanogadzira lens vanopinza chigadziko kana firimu layer yemalenzi nesirivha halide microcrystals. Kana yaiswa kuchiedza chakasimba, sirivheri halide inoora kuita maion esirivheri uye halide ions, ichitora yakawanda yechiedza cheultraviolet uye chimwe chiedza chinooneka. Kana chiedza chiri mumhoteredzo chichidzima, maion esirivheri nehalide ions zvinosangana zvakare kuita sirivheri halide pasi pekudzikisira kuita kwecopper oxide, zvichiita kuti ruvara rwelenzi rwureruke kusvika rwave pachena uye nekujeka zvakare.
Shanduko yeruvara mumalensi ephotochromic mhedzisiro yekutevedzana kwemakemikari ekuchinja, nechiedza (kusanganisira chinooneka uye ultraviolet mwenje) ichiita basa rakakosha mune izvi maitiro. Nomuzvarirwo, kushanda kwemaitiro ekuchinja-mavara kunokonzerwa nemwaka uye mamiriro ekunze, saka haisi nguva dzose kuchengetedza maitiro anowirirana uye akagadzikana.
Kazhinji kutaura, mumamiriro ekunze ezuva, kusimba kwemwaranzi ye ultraviolet kwakasimba, zvichitungamira kune yakanyanya kusimba photochromic reaction, uye lenzi dzinosviba zvakanyanya. Kusiyana neizvi, pamazuva ane makore, kana mwaranzi yeUV uye kusimba kwechiedza zvakaderera, malenzi anoita seakareruka. Uyezve, sezvo tembiricha inokwira, ruvara rwephotochromic lenses runoreruka zvishoma nezvishoma. Sezvineiwo, kana tembiricha yadonha, lenzi zvishoma nezvishoma anosviba. Izvi zvinodaro nekuti pakupisa kwepamusoro, maion esirivheri nehalide ions, ayo akange amboora, anoderedzwa achidzokera kusirilver halide pasi pesimba rakawanda, achirerutsa ruvara rwemalenzi.
Nezve photochromic lenses, kune zvakare mimwe mibvunzo yakajairika uye mapoinzi eruzivo:
Ko mafotochromic lenses ane yakaderera mwenje transmittance / kujeka kana ichienzaniswa neyakajairwa lenzi?
Yepamusoro-mhando photochromic lenses haina ruvara zvachose kana isina kuvhurwa uye haina yakaderera mwenje transmittance pane akajairwa lenzi.
Sei photochromic lenzi isingachinji ruvara?
Kushaikwa kwekuchinja kwemavara mu photochromic lenses kunoenderana nezvinhu zviviri: mamiriro ekuvhenekesa uye iyo photochromic agent (silver halide). Kana vakasachinja ruvara kunyangwe muchiedza chakasimba uye nemwaranzi yeUV, zvingangoita kuti iyo photochromic agent yakakuvadzwa.
Ko iyo yekuchinja-ruvara mhedzisiro yephotochromic lenses ichawedzera nekufamba kwenguva?
Kufanana nechero lenzi, photochromic lenses zvakare ine hupenyu hurefu. Nekutarisirwa kwakakodzera, ivo vanowanzogara makore anopfuura 2-3.
Nei mafotochromic lenzi achisviba zvachose nekufamba kwenguva?
Kana mafotochromic lenzi akasviba nekufamba kwenguva uye asingakwanise kudzoreredza kujeka, imhaka yekuti mumiriri wavo wefotochromic haakwanise kudzoka kumamiriro ayo ekutanga mushure mekuchinja ruvara, zvichikonzera kusara kwetindi. Chiitiko ichi chinowanzoitika mune yakaderera-mhando lenzi, nepo yakanaka mhando photochromic lenses haizove nenyaya iyi.
Sei grey lenses ari anonyanya kuzivikanwa pamusika?
Malenzi egrey anogona kutora infrared uye 98% ye UV mwaranzi. Kubatsira kukuru kwegrey lenses ndeyekuti haashandure mavara ekutanga ezvinhu, zvinobudirira kuderedza kusimba kwechiedza. Ivo vanotora mwenje wakaenzana pane ese ma spectrum, saka zvinhu zvinoratidzika zvakasviba asi zvisina kukosha kwemavara kukanganisa, zvichipa maonero echokwadi uye echisikigo. Pamusoro pezvo, grey iruvara rwakarerekera, runokodzera munhu wese, ichiita kuti ive yakakurumbira mumusika.
