Explanation

All three items contain plastic, though not always in an obvious form.

Cigarette filters are made of cellulose acetate (a plastic polymer), not cotton. They are non-biodegradable and release microplastics and toxic chemicals into the environment.

Eyeglass lenses are made using polycarbonate or CR-39, both of which are plastic polymers, preferred for being lightweight and impact-resistant.

Car tyres contain synthetic rubber and plastic polymers (petrochemical-based), making them partly plastic-based.

Thus, all three are linked to plastic pollution and circular economy concerns.
