Iiglasi zokuthintela ukukhanya okuluhlaza ziye zanda kakhulu kwiminyaka yamuva nje, kwaye abantu abaninzi bazibona njengesisombululo esinokuthi sinciphise ubunzima bamehlo kunye nokuphucula umgangatho wokulala.Ukusebenza kwezi glasi sisihloko esinomdla kwaye sikhuthaze izifundo ezahlukeneyo kunye neengxoxo.Kweli nqaku, siza kuphonononga iingenelo ezinokubakho zeeglasi ezibhlowu zokuthintela ukukhanya, inzululwazi ngasemva kwazo, kunye nezinye izinto ekufuneka uzikhumbule xa uzisebenzisa.Ukukhanya okuluhlaza okwesibhakabhaka kukukhanya okuphezulu kwamandla, ubude obufutshane obukhutshwa zizikrini zedijithali, ukukhanya kwe-LED, kunye nelanga.Ukuvezwa kukukhanya okuluhlaza okuvela kwizikrini, ngakumbi ebusuku, kuphazamisa umjikelo wendalo wokuvuka komzimba ngokucinezela ukuveliswa kwe-melatonin, ihomoni elawula ukulala.Ukongezelela, ukuvezwa ixesha elide ekukhanyeni okuluhlaza okwesibhakabhaka kudityaniswa noxinzelelo lwamehlo edijithali, imeko ebonakaliswa kukungakhathali kwamehlo, ukoma, kunye nokudinwa.Iiglasi eziluhlaza okwesibhakabhaka ziyilelwe ukuhluza okanye ukuvala ukukhanya okuluhlaza okoko kuncitshiswe ukukhanya okuluhlaza okufikelela emehlweni akho.Ezinye iilensi zenzelwe ngokukodwa ukujolisa awona maza amaza ayingozi okukhanya okuluhlaza okwesibhakabhaka, ngelixa ezinye zinokuba nesiphumo sokuhluza ngokubanzi.Umbono ongemva kwezi glasi kukunciphisa iziphumo ezingalunganga zokukhanya okuluhlaza okwesibhakabhaka kwimpilo yamehlo kunye neepateni zokulala.Uphononongo oluninzi luphande ifuthe leeglasi ezivala ukukhanya okuluhlaza ekudinweni kwamehlo kunye nomgangatho wokulala.
Uphononongo luka-2017 olupapashwe kwi-Journal of Adolescent Health lufumene ukuba abathathi-nxaxheba abanxibe iiglasi zokuthintela ukukhanya okuluhlaza okwesibhakabhaka ngelixa besebenzisa izixhobo zedijithali bafumana iimpawu ezincitshisiweyo zoxinzelelo lwamehlo xa kuthelekiswa nabathathi-nxaxheba abangazange banxibe iiglasi.Olunye uphononongo olupapashwe ngo-2017 kwijenali yeMpilo yokulala ibonise ukuba ukunxiba iiglasi zokuthintela ukukhanya okuluhlaza ebusuku kunokuphucula umgangatho wokulala ngokwandisa amanqanaba e-melatonin kunye nokunciphisa ixesha elithathayo ukulala.Kwelinye icala, ezinye izifundo ziye zathandabuza ukusebenza ngokupheleleyo kweeglasi zokuthintela ukukhanya okuluhlaza.Uphononongo luka-2018 olupapashwe kwijenali ye-Ophthalmology kunye nePhysiological Optics yagqiba ukuba ngelixa ukukhanya okuluhlaza okwesibhakabhaka kunokubangela ukungathandeki okubonakalayo, ubungqina bokuba iilensi zokucoca ukukhanya okuluhlaza okwesibhakabhaka zinokunciphisa ezi mpawu azingqinelani.Ngokunjalo, uphononongo luka-2020 olupapashwe kwiDatha yeCochrane yoPhononongo oluCwangcisiweyo lufumene ubungqina obaneleyo bokuxhasa ukusetyenziswa kweeglasi zokucoca ukukhanya okuluhlaza ukunciphisa ubunzima bamehlo edijithali.Nangona iziphumo zophando zixubene, abantu abaninzi baxela ukuphuculwa kwe-subjective kwinduduzo yamehlo kunye nomgangatho wokulala emva kokunxiba iiglasi zokuthintela ukukhanya kubomi babo bemihla ngemihla.Kubalulekile ukuqaphela ukuba impendulo yomntu kwezi glasi inokwahluka ngokusekelwe kwizinto ezifana nexesha lokuvezwa kwesikrini, ukuba sesichengeni somntu kubunzima bamehlo, kunye neepatheni zokulala ezikhoyo.Xa uqwalasela ukusebenza okunokwenzeka kweeglasi zokuthintela ukukhanya okuluhlaza okwesibhakabhaka, kubalulekile ukuqonda ukuba ezi glasi azikho isisombululo esilinganayo.Izinto ezinjengomgangatho weelensi, amaza athile okukhanya okuluhlaza ekujoliswe kuwo, kunye nokwahluka komntu ngamnye kwifiziyoloji yamehlo kunye nobuthathaka bokukhanya konke kuchaphazela iziphumo ezibonwayo zokunxiba ezi glasi.Ukongeza, ukuthatha indlela epheleleyo kwimpilo yamehlo kunye nococeko lokulala kubalulekile.Ukongeza ekusebenziseni iiglasi zokuthintela ukukhanya okuluhlaza, ukuthatha ikhefu lesikrini rhoqo, ukulungelelanisa ukukhanya kwesikrini kunye nesetingi yokuthelekisa, ukusebenzisa isibane esifanelekileyo, kunye nokuziqhelanisa nemikhwa elungileyo yokulala zizinto ezibalulekileyo zokugcina impilo yamehlo ngokubanzi kunye nokukhuthaza ukulala ngokuzolileyo.
Konke kuzo zonke, ngelixa ubungqina besayensi malunga nokusebenza kweeglasi zokuthintela ukukhanya okuluhlaza okwesibhakabhaka bungagqibekanga, kukho inkxaso ekhulayo yokukwazi kwabo ukunciphisa ubunzima bamehlo kunye nokuphucula ubuthongo kwabanye abantu.Ukuba ufumana ukungonwabi ukusuka kwixesha elide lesikrini okanye unengxaki yokulala emva kokusebenzisa izixhobo zedijithali, kunokuba kufanelekile ukuba ucinge ngokuzama iiglasi zokuthintela ukukhanya okuluhlaza.Nangona kunjalo, ukusetyenziswa kwabo kufuneka kuthathelwe ingqalelo njengenxalenye yokhathalelo lwamehlo olubanzi kunye nenkqubo yokucoceka kokulala, kwaye ukhumbule ukuba iimpendulo zomntu ngamnye zinokwahluka.Ukubonisana nengcali yokhathalelo lwamehlo kunokubonelela ngesikhokelo somntu malunga nendlela yokufaka iiglasi zokuthintela ukukhanya okuluhlaza kubomi bakho bemihla ngemihla.
