Cultural Note

In Chinese culture, eye health is often emphasized, especially in communities where outdoor activities are prevalent. Pterygium is seen as a condition that can be linked to lifestyle choices, such as spending time in sunny environments without proper eye protection.

Memory Tip

Think of 胬 as a 'nurturing' tissue that grows on the eye, reminding you to protect your eyes from the sun. The left part 背 (bèi) resembles a shield, implying protection, while the right part is related to the eye's surface, connecting to the idea of a growth.
