Niba uri nyir'imodoka cyangwa myopic, ugomba kwitondera cyane.Mu gihe cyizuba, ntugashyire ibirahuri bya resin mumodoka!

Niba ikinyabiziga gihagaze ku zuba, ubushyuhe bwo hejuru buzatera kwangirika kwikirahure cya resin, kandi firime iri kumurongo byoroshye kugwa, noneho lens izabura imikorere ikwiye kandi igire ingaruka kubuzima bwicyerekezo.

Imiterere yibirahuri byinshi bya resin igizwe nibice bitatu, kandi igipimo cyo kwaguka kwa buri cyiciro kiratandukanye.Niba ubushyuhe bugeze kuri 60 ℃, lens izahinduka urujijo, nka mato mato mato.

Ubushakashatsi bumwe bwerekana ko iyo ubushyuhe bwo hanze bugera kuri 32 ℃, ubushyuhe buri mumodoka bushobora kuba hejuru ya 50 ℃.Muri ubu buryo, indorerwamo zerekanwa ku kinyabiziga ziroroshye kwangirika.
