Lensike ya Polyakarubone ni amahitamo meza kubakora siporo, ibidukikije byangiza akazi, mumyenda yimyambarire cyane cyane kubana.
Ibikoresho bisanzwe bya plastiki bifashisha uburyo bwo kubumba, mugihe pelletike ya polikarubone ishyushye kugeza aho ishonga hanyuma igaterwa mumashanyarazi. Bituma lensike ya polyakarubone ikomera kandi ikarwanya ingaruka. Nyamara, utwo turemangingo ntidushobora kwihanganira, bityo, bisaba igifuniko kidasanzwe.
