Meet M Missoni's brand-new True Grass eyewear collection, updating a range of classic acetate frames with a sustainable twist. Each biodegradable polypropylene pair substitutes 35% of their normal plastic content with plant-based materials, as demonstrated by the green "Grass Based" lens print. Combining contrasting opaque tones for a colour-block look, these cateye optical glasses are embellished with a debossed logo on the temple and signature half zig zag end tips.
