Kuyandama kwamaso

Makina oyandama omwe nthawi zina mumawona pamaso panu samakhala pamaso panu, koma mkati mwawo. Malo oyandamawa ndi tizidutswa tating'onoting'ono ta ma cell tomwe timayenda mozungulira timadzimadzi tomwe timadzaza kuseri kwa diso lanu. Zitha kuwoneka ngati mawanga, mabanga, thovu, ulusi, kapena mapiko. Akuluakulu ambiri amakhala ndi ma float ochepa. Nthawi zina zimatha kuwoneka kwambiri kuposa nthawi zina, monga momwe mukuwerenga.

Mukawona kuwonjezeka kwadzidzidzi kwa zoyandama kapena ngati muwona zoyandama limodzi ndi kunyezimira kwa kuwunika m'mbali mwanu, ichi chitha kukhala chizindikiro cha kupindika kwa diso kapena gulu. Pitani kwa dokotala wa diso kapena chipinda chodzidzimutsa ngati muli ndi izi.

Nthawi zina phompho lolimba kapena lamdima limasokoneza kuwerenga. Posachedwa, mankhwala a laser apangidwa omwe atha kuthetsa mtundu wamtunduwu kuti usavutitse kwambiri.
