    Ibicuruzwa

    Kuki Guhitamo CR-39 Amashanyarazi?

    Crystal Vision (CR) ninziza zo mu rwego rwo hejuru zakozwe na imwe mu masosiyete akomeye ku isi.
    CR-39, cyangwa allyl diglycol karubone (ADC), ni polymer ya plastike ikunze gukoreshwa mugukora indorerwamo z'amaso.
    Amagambo ahinnye yerekana “Columbia Resin # 39”, yari formula ya 39 ya plastike ya termosetting yakozwe n'umushinga wa Columbia Resins mu 1940.
    Ufitwe na PPG, ibi bikoresho birahindura gukora lens.
    Kimwe cya kabiri kiremereye nkikirahure, ntibishoboka cyane kumeneka, hamwe nubwiza bwa optique hafi nkikirahure.
    CR-39 irashyuha hanyuma igasukwa muburyo bwiza bwikirahure - guhuza imiterere yikirahure cyane.

    Itara ry'ubururu-Violet

    Impinduka imwe nini ni itara ry'ubururu. Itara ry'ubururu ntabwo ari shyashya - ni igice kigaragara.

    Izuba ryabaye isoko imwe rukumbi yumucyo wubururu kuva igihe cyatangiriye hamwe no kugaragara hanze inshuro 500 kurenza inzu. Guhindura urumuri rwubururu bizana ubumenyi bwacu bwingaruka kuri sisitemu yo kureba. Nkesha ubushakashatsi bwakozwe na Paris Vision Institute na Essilor, ubu tuzi ko impfu nyinshi zingurube zingurube zibaho mugihe utugingo ngengabuzima twibasiwe n’imirasire yubururu-violet hagati ya 415nm-455nm, hamwe na 435nm

    Ni ubuhe buryo bwiza bwo guhitamo tugomba kugabanya urumuri rw'ubururu?

    Ntabwo itara ry'ubururu ryose ari ribi kuri wewe. Nyamara, Umucyo Wangiza Ubururu ni.

    Isohora mubikoresho abarwayi bawe bakoresha burimunsi - nka mudasobwa, terefone zigendanwa, na tableti.

    Kandi kubera ko 60% byabantu bamara amasaha arenga atandatu kumunsi kubikoresho bya digitale, abarwayi bawe birashoboka ko bazabaza icyo bakora kugirango barinde amaso yabo kutumara igihe kinini cyumucyo wubururu.

    Ibyingenzi

    • Itara ry'ubururu-violet kuva kuri 415-455 nm ryagaragaye nkimpamvu itera imbaraga za okiside itera imbaraga kandi ikanabuza kwirwanaho, bityo bumwe muburyo bwumucyo bwangiza retina.

    • Ingaruka zishobora kuba ziterwa no kwiyongera kwurumuri rwubururu zirashobora guhinduka bitewe nubuhanga bugezweho bwamaso.

    • Uburezi bw'abarwayi ni ngombwa mu gukangurira abantu kumenya ingaruka mbi z'umucyo w'ubururu hamwe n'ibisubizo bihari byo gukumira.

    • Itara ry'ubururu rigizwe n'imirase yangiza (ubururu-violet) kandi ifite akamaro (ubururu-turquoise). Ni ngombwa ko lens y'amaso ihagarika iyambere ikareka ikanyura.

    • Iyo ugereranije ibisubizo bitandukanye bya optique yo kuyungurura urumuri rwubururu ni ngombwa kuzirikana ko umubare wurumuri rwubururu-violet wafunzwe ari ngombwa gusa ahubwo nuburebure bwumurongo wahagaritswe.
