These sustainable unisex readers by Piranha Optics are both environmentally friendly and classically stylish! Lightweight and comfortable, the Crater reading glasses have dark gray frames made from Eco-Pact recycled plastic. The temples are constructed of biodegradable BPA-free wheat grass composite. The clear acrylic lenses are fully magnified, and come in a variety of diopters.
Piranha Optics is proud to bring you Natural Earth readers - a line that focuses on new sustainable materials and technology. And because every little bit helps, 1% of all profits made from these readers will go to support our National Parks and their personnel.
When our Natural Earth readers reach the end of their lifecycle, the elements can be separated into separate recycling. We recommend placing the PET1 plastic water bottle frames into bottle recycling. The acrylic lenses can be popped out and placed into plastic recycling. You can write "acrylic" on the lens with marker so they can be sorted appropriately. The metal hinges and screws can be placed into metal recycling. The composite and bamboo materials are biodegradable and can be composted. Industrial composting is the fastest way to break down wheat and tree bark composite, and backyard composting may take up to half a year to break down plant-based materials.
