Kaŵirikaŵiri, kunyezimira ndi chinthu chimene kuwalako kumakhala konyezimira ndiponso konyezimira, kuchititsa diso la munthu kuona zinthu bwinobwino, zosakhala bwino ndi maso a munthu, kapena zosaoneka nkomwe.Chifukwa chake, mawonekedwe owunikira amafunika kuchepetsa kuwala.
Tanthauzo lokhazikika la kunyezimira ndi:
Chochitika chowoneka chomwe chimayambitsa kusapeza bwino kapena kuchepetsa kuthekera kowona mwatsatanetsatane kapena zinthu chifukwa cha kufalikira kosayenera kapena kusiyanasiyana kowala pamawonekedwe, kapena kukhalapo kwa kusiyana kowala kwambiri.- "Architectural Lighting Terminology Standard" JGJ/T 119-2008
Kuunikira pamasewera kumagwiritsa ntchito glare index (GR) kuwunika kuchuluka kwa kunyezimira, komwe ndi gawo lamalingaliro kuyeza momwe mabwalo amachitira masewera akunja ndi zida zina zowunikira panja kuti achepetse kuoneka komanso kusamasuka komwe kumachitika chifukwa cha maso a anthu.Ndi mulingo wa CIE.
Mu formula:
Lvi-kuwala kwa nsalu yotchinga (cd/m2) yopangidwa ndi kuwala komwe kumapangidwa ndi nyali kugunda mwachindunji m'maso;
Lve-kuwala kwa chinsalu chowala (cd/m2) chifukwa cha kuwala komwe kumachitika m'maso chifukwa cha chilengedwe.
Mitundu yosiyanasiyana ya GR imawonetsa magawo osiyanasiyana a kunyezimira, monga momwe zikusonyezedwera mu Gulu 1.
Table 1 Glare Index ndi Glare Degree
| Glare Quality Class GF | Glare Level | Mtengo wapatali wa magawo GR |
| 1 | Zosavomerezeka | 90 |
| 2 | - | 80 |
| 3 | Zosokoneza | 70 |
| 4 | - | 60 |
| 5 | Zosavomerezeka | 50 |
| 6 | - | 40 |
| 7 | Zomveka | 30 |
| 8 | - | 21 |
| 9 | ND | 10 |
GR=50 yodziwika padziko lonse lapansi ndiyo kunyezimira kovomerezeka kwa anthu, kotero muyezo wapadziko lonse lapansi umafuna kuti GR ya kuyatsa kwamasewera kumalo ochitira mpikisano isapitirire 50.
Kunena zowona, ndondomeko yomwe ili pamwambayi ndi yoyenera kuunikira kunja kwa malo, ndipo dziko langa lawonjezera ntchitoyi ku malo amkati, ndipo yakhala ikugwiritsidwa ntchito kuyambira 2007.
Nthawi zambiri kunyezimira ndi kwa diso la munthu, lomwe limatha kuwonedwa kuchokera ku tanthauzo la kunyezimira.Komabe, ndi chitukuko cha kuwulutsa zamasewera, mipikisano yayikulu imayikanso patsogolo zofunikira zamakamera.Mwachitsanzo, Masewera a Olimpiki amafuna kuti GR ya kamera isapitirire 40. Kuti mudziwe zambiri, chonde onani zolemba za wolemba "Sports Lighting Design Manual" (lofalitsidwa ndi China Electric Power Press).
