Abakhiqizi bezingilazi bakhiqiza lawa ma-lens ukuze balungise ukubona kude kakhulu.Lokho kusho ukuthi kunzima ukubona izinto eduze.
Ishadi lamandla lelensi yokuxhumana
Qhubeka ufunda ukuze uthole ulwazi olwengeziwe ngamalensi e-lenticular, okubandakanya ukusetshenziswa kwawo ngale kokulungisa umbono.
Amandla aphezulu ngokuvamile asho izibuko ezisindayo kakhulu.Ukuvimbela amalensi ukuthi angashubi kakhulu ukuba angalingana, abakhiqizi bezibuko zamehlo benza amalensi e-biconvex.
Ungacabanga ngelensi yelensi njengamalensi amabili ahlukene apakishwe phezu kwelinye.Abakhiqizi bezingilazi ngokuvamile benza amalensi anosayizi ojwayelekile bese bebeka amalensi amandla aphezulu endaweni encane.Amalensi alungisa umbono wakho uma ubheka kuleyo ndawo ethile. .
Ama-Bifocal amalensi akhethekile akuvumela ukuthi ubone kangcono uma ufunda ubhekise ikhanda phansi.Uma ubheka phezulu, ungabona ezinye izinto ngokucacile.
Amalensi e-Lenticular asetshenziswa njengamalensi okuxhumana kanye nezibuko zamehlo.Ezinhlobonhlobo zezibuko, afika ngengilazi noma ngepulasitiki.
Abakhiqizi bezibuko noma bezinto ezibonakalayo bangashintsha amalensi e-lenticular ukuze bakusize ubone izinto ngokuqhubekayo noma ngokuseduze ngokucacile.
Kwesinye isikhathi odokotela batusa amalensi e-cylindrical spectacle entsheni yabantu abadala abanokukhubazeka kokubona okumaphakathi kuya komaphakathi besebancane.

Njengomphumela, abakhiqizi be-optical basebenzisa amalensi e-lenticular ukuze bakhe izibonisi zesikrini se-3-D TV namahedisethi wezinhlelo zento engekho ngokoqobo.
Ukuphrinta kwe-Raster noma ukubeka izendlalelo nakho kukuvumela ukuthi ubone isikhangiso sakho nge-3D.Ngokuvamile udinga ukuma noma uhlale e-engeli ukuze ujabulele umphumela ogcwele.
Uma une-cataract, ungase uzuze kumalensi e-lenticular.Lokhu kwenzeka lapho i-lens esesweni lakho iba namafu futhi iphazamisa ukubona kwakho.Udokotela wakho wamehlo ngokuvamile angalungisa ukubona kwakho ngokufaka amalensi amasha.

Ngokusho kwe-Consumer Reports, ilensi ejwayelekile ye-bifocal ibiza cishe u-$105. Kodwa lezo ezisetshenziselwa ukulungisa amakhathakhatha noma ezinye izinkinga zokubona zingabiza kakhulu.
Amalensi aqhubekayo angenye yamalensi e-biconvex abanye abantu abangawathola bekhululeke kakhudlwana ukuwagqoka.
Nge-cataract, udokotela wakho angenza izivivinyo, ezifana nokuhlolwa kwe-retinal ngokunwetshwa kwamehlo noma ukuhlolwa kwesibani sokusikwa.
Uma udokotela wakho encoma amalensi angama-cylindrical, uzokufundisa ukuthi uwagqoke kanjani ngendlela efanele kanye nendlela yokulingana namalensi.
Ilensi yelensi wuhlobo lwamalensi olungakusiza ukuthi ubone kangcono noma udale imiphumela ekhethekile ye-3-D.
I-bifocal iyisibonelo esivamile selensi ye-lenticular, nakuba izinketho eziyinkimbinkimbi zamalensi nazo ziyatholakala.
Izinhlungu zekhanda ezibangelwa imiyalelo emisha yengilazi yamehlo zivamile. Ngokuvamile, ziyanyamalala phakathi nezinsuku ezimbalwa njengoba amehlo akho ejwayela incwadi yakho entsha kadokotela...
