Polarized magirazi ezuva: zvavari uye zvakakosha mabhenefiti

Zvemukati

• Kubatsira kukuru
• Kukosha kwemasefa mumirazi yezuva

Iyo yakasungirirwa girazi rezuva rudzi rwemagirazi ane malenzi akagadzirwa kuchengetedza maziso kubva kumwaranzi yechiedza ayo anoratidzwa pamusoro pemeso. UVA mwaranzi ndiyo iyo inonyanya kukanganisa pasi pevhu uye nekudaro yakakosha mune yakanaka magirazi ezuva. Nekudaro, magirazi ezuva akakodzera kwazvo ekuchengetedza hutano hwemaziso ndeuyo ane mafirita matatu: UVA, UVB uye UVC. Magirazi akaparadzirwa, kune rumwe rutivi, anopa nyaradzo kuchiono sezvavanokwanisa kuronga nzira iyo mwaranzi inopinda nayo mumaziso, ichideredza kupenya.

Magirazi ezuva akakosha kuchengetedza maonero ako pamazuva ane zuva uye kunyange pamazuva ane makore, nekuti anodzivirira kusangana kwakananga nemwaranzi yeUV, kudzivirira kukura kwezvirwere zvemaziso mukuwedzera pakupa hukuru hwekuona. Neichi chikonzero, magirazi anofanirwa kupfekwa nevanhu vese pamazuva ane zuva, kunyangwe nevacheche nevana, kana vachitamba panze.

Kubatsira kukuru

Magirazi egirazi ane lenzi dzakakwenenzverwa anogona kuve nemabhenefiti akati wandei ehutano, iwo makuru acho ari:

1. Dzivirira maziso ako kubva kune zvinokuvadza zvezuva, kuva mubatsiri mukuru kudziviriro yezuva inoshandiswa paganda;
2. Dzivirira kukwegura kusati kwasvika uye kuoneka kwemakwenzi akatenderedza maziso nehuma;
3. Kuderedza njodzi yekuparara nezvimwe zvirwere zvemaziso;
4. Yakakura yekuona nyaradzo kana uchifamba panze;
5. Deredza kupenya uye chiedza;
6. Kuvandudza kupinza zvaunoona;
7. Deredza huzi uye kuwedzera ruzivo rwemavara.

Kunyangwe ivo vachikurudzirwa kuti vashandiswe mune ese mamiriro, iyo polarized lens inonyanya kukodzera kushandiswa pamhenderekedzo yegungwa, yekutyaira uye kutamba mitambo yemvura kana muchando, uko zuva rinopenya zvakanyanya zvichikonzera kusagadzikana kukuru mumaziso.

Kukosha kwemasefa mumirazi yezuva

Magirazi egirazi emhando yepamusoro anodhura, asi anowanzo aine mafirita akakosha anodzivirira kufamba kwechiedza chezuva, kudzivirira uye kuvimbisa hutano hwemaziso. Ona tafura iri pazasi yekukosha kweaya mafirita mana pamasikati ezuva:

Kune akatiwandei mamodheru pamusika kune ese maface marudzi. Zvimwe zvinogona kutogadzirwa kuyera kusvika padanho rinodiwa nemunhu, uye zvinogona kutsiva kushandiswa kwemagirazi akajairika pamazuva ane zuva.

Magirazi ezuva akadhura uye emanyepo haafanire kutengwa sezvo isu tisingazive kana achidzivirira maziso kubva kuzuva, nekuti anogona kunge asina mafirita anodikanwa, uye anogona kukonzeresa zvirwere zvemaziso, nekuti iyo yakasviba iyo lens, inowedzera kuwedzera lens uye mudzidzi uye nekudaro akakura zvakanyanya kune anokuvadza ezuva. Zvisinei, huwandu hwakawanda hwezvigadzirwa zvinotengeswa muBrazil zvine mafirita akanaka, kunze kwemagirazi ezuva akapwanywa uye anotengeswa kune vanotengesa mumugwagwa, semuenzaniso.

Kuti uve nechokwadi chekudzivirira kwezuva kwakazara, pamusoro pekushandisa girazi rezuva remuviri uye kumeso, zvinokurudzirwawo kushandiswa kwezuva nezuva magirazi ezuva akanaka, ane UVA, UVB uye UVC mafirita kana magirazi ezuva ane lenzi rakadzvanywa.
