- I-computer vision syndrome ibangela ukucindezeleka kwamehlo nokomisa ngenxa yomzamo wokugxila kanye nokuncipha kokucwayiza.
- Ukukhanya okuluhlaza okwesibhakabhaka okuvela ezikrinini kuphazamisa imijikelezo yokulala futhi kungabangela ukucasuka kwe-retina.
- Ukusebenzisa umthetho we-20-20-20 nokulungisa ibanga nokukhanya kubalulekile ekuvimbeleni ukulimala kwamehlo.
Kulezi zinsuku, cishe akunakwenzeka ukuphila ngaphandle kwe-smartphone eceleni kwethu. Sesijwayele ukuhlola izinkundla zokuxhumana, ukuphendula ama-imeyili, noma ukuphequlula i-inthanethi noma nini, noma kuphi, ngisho nokulala embhedeni ngaphambi kokulala.
