Microorganisms in water can adhere to your lenses and cause infections. It’s better to be safe than sorry!

The Biofilm Battle

Microorganisms are incredibly adept at surviving, adapting, and cohabiting with their environment. When it comes to your lenses, they form biofilms – slimy matrices that shield them from disinfection.

These biofilms can harbor harmful bacteria, fungi, and other microorganisms, posing a threat to your eye health. Understanding the challenges posed by biofilms is crucial in combating contact lens-related eye infections.

Here’s what you need to know:

1. Fungal Intruders: Fungi are particularly resilient and can infiltrate biofilms with ease.

They utilize biofilm structure to shield themselves from disinfectants, making them a formidable opponent. 2.

Disinfection Dilemma: Common lens solutions struggle to effectively eradicate biofilms, especially those infested with fungi. Unfortunately, this leaves our lenses vulnerable to infection, even if we follow the recommended cleaning routine diligently.

3. Breaking the Barrier: Researchers are working tirelessly to develop advanced disinfection methods that can demolish biofilms.

Until then, following a strict cleaning routine, and seeking prompt medical attention at the first sign of infection, is our best defense.
