Ukuba ufaka lakho elifutshane-sightedness, ukuza kuthi ga ngoku-sightedness okanye astigmatism (okanye, ukuba oko kuyasebenza apha, kanjalo ubudala ingaba kude ibe ezichaphazelekayo-sightedness), kufuneka imoto kuba obubonakalayo aid.

Uvunyelwe ukuba drive, ke ngoko, zange ngaphandle umbono, ukuba kunjalo kuchazwe kwi-mvume. Abo sele sephepha-mvume lokuqhuba, kufuneka kufuneka ukhangele kuphela eyiyeyakhe zokhuseleko, yithi rhoqo ngeliso uvavanyo ngomhla optician, ukuba amaxabiso abanalo deteriorated.

ishumi ipesenti ye-indoda abantu behlabathi).
I-Red-Luhlaza-ubuthathaka iza ngeendlela ezininzi ezahluka-hlukileyo shades. Ezona Ezichaphazelekayo uza ukubona imibala Red kwaye Oluhlaza, hayi ke oqaqambileyo, kodwa endaweni yoko njengoko shades ka-ngwevu. Ngubani ezichaphazelekayo nge-i-Red-Luhlaza ubuthathaka, usakwazi yokuthenga i-mvume. A Glasses okanye ekhethekileyo prescription glasses akuvumelekanga (okanye kuphela uphando). Nanku umzekelo umbala umbono uvavanyo: Kutheni kubalulekile ukuze ukwazi aqonde imibala. Kufuneka ukwazi, umzekelo, ukuba flashing ukukhanya kukuba Bomvu okanye Okwesibhakabhaka. Wasiqhekeza ezongeziweyo kwi balance ye-awandulela isithuthi ingaba red, xa ukukhanya imigca ethe ingaba Ganges mhlophe. Ngokuqhelekileyo, ukukhanya kwi traffic ezongeziweyo ngu cacisa: phezulu kukuba bomvu, ezantsi ngu oluhlaza. Kodwa yintoni ukuba mnye kuphela lamp ikhona, apho mhlawumbi bomvu okanye oluhlaza. Oku akumelanga kuba road, nangona kunjalo, kodwa unako kwenzeka ngendlela ethile kwiimeko (umz, ukwakhiwa zephondo, Parking garages).
