Ese amadarubindi ashobora kivura umutwe udakira?

 

lunette (amadarubindi) ashobora kugabanya cyangwa gukuraho umutwe mu gihe icyo kibazo giterwa no kutabona neza.

Dore uko bimeze:

Umutwe ushobora guterwa no:

  • Kureba nabi (vision problem): nk’iyo umuntu afite myopia (kutareba kure), hypermetropia (kutareba hafi), cyangwa astigmatism.
  • Guhatiriza amaso igihe usoma, ukoresha telefone, mudasobwa cyangwa ureba ibintu byinshi udafite lunette ibikwiriye.
  • Presbyopia (gusaza kw’amaso), ibaho ku bantu bageze mu myaka yo hejuru (40+), aho umuntu atakibona neza ibiri hafi.

Lunette zishobora kugufasha mu buryo bukurikira:

  1. Guhagarika umutwe uterwa no guhatiriza amaso.
  2. Gutanga uburumbuke mu maso, ukareba neza udahangayitse.
  3. Kugabanya stress iva ku kuba umuntu atabona neza.

Icyo ugomba gukora:

  1. Gana muganga w’amaso (optométriste cyangwa ophtalmologue).
  2. Azakupima amaso neza, amenye niba ikibazo cy’umutwe gifitanye isano n’amaso.
  3. Niba bibaye ngombwa, azagusabira lunette ziboneye.

Icyitonderwa:

✔️ Niba umutwe udashira n’iyo wambaye lunette, ushobora kuba hari ikindi kibazo (nko kubura amazi, stress, indwara y’uruhu, cyangwa infection). Ibyo nabyo bisaba kwivuza.

Waba ushaka ko ngufasha gushaka aho bapimira amaso hafi yawe cyangwa aho bagurisha lunette?
