Zviratidzo nezviratidzo
Mumwe munhu anongotarisa angangotarisa paanoedza kuona zvinhu zviri kure. Vanogonawo kugara pedyo neTerevhizheni kana kuunza mabhuku zvikuru pedyo nemeso avo pavanoverenga.
Dzimwe nguva kutarisa mberi kunoita kuti vanhu vasanyatsoziva zvinhu zvisiri kure.
Zvinokonzera
Kuongororwa kunoitika apo ziso reziso rinenge rakareba kudarika rinowanzoitika, kana apo cornea inopfuura yakawandisa. Iyi mamiriro ezvinhu anoita kuti chiedza chiise mberi pamberi pe retina kwete panzvimbo chaiyo pamusoro payo. Mune zviitiko zvakawanda, kutarisa mberi kunotora nhaka. Zvisinei, pane humwe humwe humwe hunoratidza kuti zvakanyanya kufambidzana mabasa, zvakadai sokuverenga kwenguva yakareba kwenguva yakareba kana kutamba mitambo yemavhidhiyo kwemaawa mazhinji, mukukura kwevanhu vakuru kunogona kuita kuti usanyanya kuona. Kunyange zvazvo, vanachiremba vanoona izvi izvi muchipatara, tsvakurudzo ichiri kupatsanurwa pane izvi sechikonzero chekutarisa. Mune dzimwe nyika, huwandu hwevanhu huri pedyo, hunofungidzirwa sehutano hwehutano hwevanhu kana chirwere.
Kuziva

Nemhaka yekutarisa mberi kana kuti myopia iri kuwedzera muUnited States nedzimwe nyika dzakawanda, vabereki vanowanzoda kufarira nzira dzekudzikisa dambudziko revana ravo rokuswedera pedyo nepamusoro kana kuve pedyo nekuona.
Ongororo ichangobva kuitwa naChristine C. Shermin muna 2011 inoratidza kuti paawa imwe yega yega vana vanopedza kunze kwevhiki, dambudziko ravo rokuswedera pedyo rinodonha ne2 muzana. Uyezve, mwana akatarisa mune imwe yezvidzidzo, akapedza avhareji yenguva inenge maawa mana maawa mashomanana pavhiki kunze kwevana vanowanzogara kana vana vanotarisa. Imwe hukama hunofadza yakaongororwawo zvakare. Chidzidzo chacho chakaedza kuziva kana vana vakashandisa nguva yakawanda vachienda kunze aslo vakapedza nguva shoma vachitamba mitambo yemakombiyuta, zvakasimba pedyo nekuverenga kana kudzidza. Zvisinei, hapana hukama hwakawanikwa
