Interojo

Interojo makes contact lenses, thin, curved discs worn directly on the eye to correct vision or change eye colour.

It supplies these lenses to consumers in South Korea under its own Clalen brand, while serving international customers primarily through OEM and ODM arrangements, meaning it manufactures lenses to other companies' specifications. Listed on KOSDAQ, South Korea's tech and small-cap board, the company produces a broad portfolio spanning clear and colour lenses, daily-disposable and extended-wear formats, and functional types including lenses for astigmatism, presbyopia, and blue-light filtering, with its product mix shifting increasingly toward premium silicone-based materials.
