Ha mahlo a rōna a theoha, re lokela ho roala likhalase.Leha ho le joalo, metsoalle e meng e tloaetse ho roala lilense tsa ho ikopanya ka lebaka la mosebetsi, liketsahalo kapa e 'ngoe ea likhetho tsa bona.Empa na nka roala lilense bakeng sa astigmatism?
Bakeng sa astigmatism e bonolo, ho lokile ho roala lilense tsa mahlo, 'me ho tla thusa ho lokisa pono.Empa haeba astigmatism e tebile, u lokela ho e hlahloba ka hloko 'me u mamele keletso ea ngaka
Leha ho le joalo, haeba astigmatism ea hau e feta 175, 'me lilense tsa spherical le cylindrical li kholo ho feta kapa li lekana le 4: 1, u lokela ho nahana ka hore na u ka apara li-contact lenses.Ha e le hantle, sena se ka tsejoa feela ka mor'a optometry ea setsebi.
Hona joale ho na le lilense tse khethehileng tsa ho kopana le batho ba astigmatism 'marakeng, ke hore, lilense tse tsebahalang tsa astigmatism.Hafeela lilense tsa ho kopana li ka apesoa ka tumello ea ba boholong, u ka reka lilense tsa puisano ho latela lintlha tse fanoeng ke ba boholong.
Ka hona, hore na ho roala lilense tsa ho ikopanya ka mor'a astigmatism ho lokela ho hlahlojoa ka ho qaqileng.Haeba mahlo a hau a se a sa tšoanelehe ho roala lilense, u se ke ua hana ho roala likhalase tsa foreimi ka lebaka la ponahalo ea hau, ho seng joalo ho tla tlisa moroalo mahlong a hao le ho etsa hore mathata a hau a pono a be tebileng haholoanyane.
