Iiglasi ezibonisa indlela ezibukwayo luhlobo lweengqayi zeglasi ezintle ezenziwe ngokurisayikilisha iglasi njengezinto eziluhlaza, zityunyuzwe kwaye zinyibilikiswe kubushushu obuphezulu yigesi yendalo, ebonwa njengesphere engenambala necacileyo phantsi kwemicroscope. Isalathisi sayo sokurhawuzelela siphakathi kwe-1.50 kunye ne-1.64, kwaye ububanzi bayo ngokubanzi buphakathi kwe-100 microns kunye ne-1000 microns. Iiglasi ezibonisa indlela ezibukwa ngayo zineempawu zokuma okungqukuva, iingqayi ezincinci, ukufana, ukucaca kunye nokumelana nokuguguleka.
Iiglasi ezibonisa indlela ezisetyenziswa njengepeyinti yophawu lwendlela (ipeyinti) kwizinto ezibonisa indlela, zinokuphucula ukusebenza kophawu lwendlela, ziphucule ukhuseleko lokuqhuba ebusuku, zichongiwe kumasebe ezothutho kazwelonke. Xa imoto iqhuba ebusuku, izibane zezibane zikhanya kumgca wophawu lwendlela ngeeglasi, ukuze ukukhanya okuvela kwizibane zezibane kubonakale ngasemva ngaxeshanye, ngaloo ndlela kuvumela umqhubi ukuba abone indlela yokuqhubela phambili kwaye aphucule ukhuseleko lokuqhuba ebusuku. Kule mihla, iiglasi ezibonisa indlela ezisetyenziswa ngayo ziye zaba zizinto ezibonisa indlela ezingenakutshintshwa kwiimveliso zokhuseleko lwendlela.
Inkangeleko: icocekile, ayinambala kwaye icacile, ikhanya kwaye ingqukuva, ayinamaqamza okanye ukungcola okubonakalayo.
