The noupofu ngozi zvikuru, chando uye cortical

Pane mhando dzakasiyana wenyonganyonga kana munhu akamira kuona yorubvunzavaeni, inopenya chiedza, kana chete pakarepo kunobva upofu zvakakwana. Ngationei, chii vari mhando chaiyo upofu nako zvavari chokuita, uye rudzii rubatsiro unogona kupa.

usiku-upofu

Kana munhu ari aienda pamusoro usiku, iye nechirwere usiku upofu. The zita chirwere nokuti kuti huku mambakwedza uye rima vanorasikirwa kugona kwavo kuona zvakanaka. Uye zvinonyanya kuita pamwe huku, chirwere asina.

Pamberi yechimurenga Russia, hosha wakange vakawanda chimiro vokumaruwa, kunyanya zvinowedzerwa muchirimo.

The mashandiro kuti kuderedza yorubvunzavaeni zvakaratidzwa vakawanda ndechokuti kazhinji munhu anowedzera zvikuru susceptibility kuti chiedza murima. Vachikwanisa nokuti rima kwadzakabva yakadaro nokuda wevasungwa pamusoro rhodopsin, rine vhitamini A. Apo vhitamini mumuviri hazvikwani, ipapo rhodopsin ukasunungurwa zviduku zvakawanda, uye ziso anorasikirwa kukwanisa aro akatiita sei kutanga rima.

Naizvozvo upofu chokuita chinokosha rokushaya kana oversupply mumuviri mavhitamini A uye PP, uyewo vamwe B mavhitaminzi Zvinetso yorubvunzavaeni zvakaratidzwa - ichi ndicho rinonyatsooneka mangwanani chiratidzo zvirwere zviri mumuviri.

Zviya, masayendisiti akawana kuti vana vari kutya murima hakusi nemhaka anotyisa dzechembere kana wavo, kana muchimuka. kutya izvi zvinogona chokuita pamwe kuratidzwa zvavo usiku upofu nokushaya zvakakodzera mavhitaminzi.

Kune dzimwe zvinokonzera chirwere:

- cheshuga;

- cataract;

- zvirwere of the retina.

Asi kana izvi zvinokonzera havachafaniri, asi zvinokosha kuti zadzai muviri nengaidzo mavhitamini kuti upofu akapfuura. Kuti aite izvi, vanachiremba akarayira yakakwirira mishonga vhitamini A pachiimbwa riboflavin uye vhitamini B6. Yawapiwa - kubva shomanana kuti mwedzi, zvichienderana kwokuomerwa zviratidzo.

Zvinofanira kurangarirwa kuti, pamatunhu mishonga, vhitamini A zvinova chepfu, saizvozvowo vanoshingaira kana kuzvicheka-medicate iyi hazvibviri.

Nokuti dziviriro, unofanira kugara kudya twakadai uye nhanga, uye mumwaka - apricots nemadomasi.

chando-upofu

chirwere ichi kunoratidzwa inopenya chaizvo chezuva, kunyanya kana zuva kunooneka kubva pechiso chando. Ipapo munhu ane marwadzo mumaziso, anobvarura aibuda, pane photophobia. The retina vanhu vakadaro vane hanya kuti UV chiedza, zvinoita kuti munhu chisimbwa kune chiedza.

Sei zvakadaro maitiro kunoitika zviri chando? Chokwadi chokuti ultraviolet chiedza kunooneka kubva chando, ane zvakawanda simba nomugumisiro. Kunogona kukonzera kutsva of the retina uye kurasikirwa zvawakaratidzwa kwemazuva mashomanana. In chirwere zvikuru nounyoro, pane akatsvuka uye kuzvimba ziso, pane kuchinja pigmentation vakavakomberedza.

Nokuti chando Kudzivirira upofu inokurudzirwa kupfeka Sunglasses kana uchida kuenda kugomba rakajeka mushana chando zuva. Ndokusaka makomo uye skiers chokwadi kudzivirira meso ako.

cortical upofu

chirwere ichi hworatidza vafirwa kwakakwana wezvakaonekwa. The chinokonzera cortical upofu - vasingadzoreki kuparadzirwa munzvimbo cortical zvikamu uropi. chirwere ichi hachisi kuzvimiririra, uye pakamuka Somugumisiro atherosclerosis uye BP. Lead chepfu mumuviri kana carbon monoxide kungakonzera cortical upofu.

The pakuonekwa cortical upofu inowanzozivikanwa pashure nguva haasaruri kurasikirwa Zvinhu minda.

Cortical upofu zvinoreva mhando chetsinga kukuvara pamwero, saka kana zviratidzo yaida kutanga kutsvaka rubatsiro kwete chete kune chiremba ziso, asiwo kuna chiremba wetsinga.
