Traditionally, tortoise shell glasses were made from the shells of tortoises, specifically the hawksbill turtle. However, due to ethical concerns and strict international conservation laws, genuine tortoise shell is no longer used. Today's tortoise shell glasses are crafted from a variety of synthetic materials designed to mimic the distinctive mottled pattern of brown, black, and sometimes amber or honey. These materials include acetate, plastic that is both lightweight and durable, offering a high-quality, ethical, and environmentally friendly alternative. Acetate frame allows for rich coloration and the intricate patterns that tortoise shell glasses are known for, making them a popular choice for eyewear.
