Tetrafilcon (Hema-NVP) is a contact lens material known for its unique properties. Manufactured by Conta Optic, these lenses have an average water content of 43%. Compared to other materials, Tetrafilcon (Hema-NVP) falls within the lower range of water content. For instance, materials like Lehfilcon A and Nesofilcon A have significantly higher water content at 78%. On the other hand, materials like Lotrafilcon A and Lotrafilcon B have much lower water content at 24% and 33% respectively. Tetrafilcon (Hema-NVP) strikes a balance between moisture retention and oxygen permeability, with an oxygen permeability of 11.
