Abafundi besikole samabanga aphansi nabasekondari bazoqala amaholide abo ehlobo ngesonto. Izinkinga zombono zezingane zizophinde zibe ukugxila kwabazali.
Eminyakeni yamuva nje, phakathi kwezindlela eziningi zokuvimbela i-Myopia nokulawula, ama-lens aqhelelana, anganciphisa ukuthuthukiswa kwe-Myopia, sekudume kakhulu phakathi kwabazali.
Ngakho-ke, kanjani ukukhetha ama-lens ahlekisayo? Ngabe kufanelekile? Ayini amaphuzu okufanele uwaphawule ku-Optometry? Ngemuva kokufunda okuqukethwe okulandelayo, ngicabanga ukuthi abazali bayoba nokuqonda okungcono.
Yini ama-lens adicekile?
Ngokuvamile, ama-lens adicilela ama-lens akhiqizwanga ngokwehluleka, aklanyelwe ukuqukatha indawo ephakathi nendawo kanye nendawo engahambisani, eyinkimbinkimbi ngokwengeziwe ngokuya ngemingcele ye-optical nokufuna okuningi ngokwemibandela evamile.
Ngokukhethekile, indawo ephakathi isetshenziselwa ukulungisa i-Myopia ukuqinisekisa ukuthi "umbono ocacile", ngenkathi isifunda se-peripheral senzelwe ukukhiqiza i-medopic defocus ngomklamo okhethekile we-optical. Izimpawu ze-monyocus ze-defacus ezikhiqizwe kulezi zindawo zingavimba ukukhula kwe-axis yamehlo, ngaleyo ndlela zehlise ukuqhubeka kwe-myopia.
Uyini umehluko phakathi kwamalensi ajwayelekile kanye namalensi wokuphenya?
Ama-lens ajwayelekile we-monofocal agxila esithombeni se-Central Vision ku-retina futhi angakwazi ukubona kuphela umbono olungile, avumele umuntu abone kahle lapho egqoke;
Ama-lens akhubazekile awagcini nje ngokugxila esithombeni esiphakathi esiya e-retina ukusivumela ukuthi sibone kahle kodwa futhi sigxile ku-retina, sakha i-metina defocus ebambezela ukuthuthukiswa kwe-myopia.

Qaphela: Iziguli ezine-strabismus, umbono ongajwayelekile we-binocular, futhi i-anisometropia idinga ukuhlolwa ngudokotela futhi ibheka kufanelekile.
