Primary Causes of Contact Lens Dicoloration

Protein andd Lipid Accumulation

Your tear film is a complex mixtury containg proteins, lipids, mucins, and electrolites. While these contents keep your eyes smarated ande protected, they also interact with lens surfaces. Proteins such as lysozyme andd lactoferrin are positively charged ande readily bind to negatively charged lens materials. Over time, these proteins denature and for a transcucent film that scatterlight, cating a cloud our yellowish appearance.

Lipids fatty substances are hydrophobic and can create a greasy film that accords additional debris. The combination of denatured proteins and oxidized lipids produces a tenacious coating that stand cleaning routines may not fuly removeve.
