Contact Lens Fell? Water Risk is Real!
9 May
Summary
- Tap water can harbor dangerous microorganisms like Acanthamoeba.
- Rinsing lenses with solution may not eliminate all harmful microbes.
- Seek a doctor for redness, pain, or vision changes after lens contact.
Dropping a contact lens and rinsing it with solution might seem like a quick fix, but experts warn this can expose eyes to dangerous microbes. Tap water and sink surfaces are not sterile and can contain bacteria, fungi, and the rare but serious Acanthamoeba parasite.
When a contact lens contacts these contaminants, it can trap germs against the eye, increasing infection risk. While disinfecting solutions reduce the danger, they may not eliminate all harmful organisms, particularly Acanthamoeba. Therefore, the safest course of action for a dropped lens is often to discard it, especially if it's a daily disposable.
Reusable lenses require thorough disinfection with fresh solution. However, even with proper cleaning, a residual risk remains. The overall chance of severe infection is low, but Acanthamoeba keratitis can cause significant pain and vision problems if not treated promptly.
Individuals who have worn a potentially contaminated lens should remain vigilant for symptoms like redness, pain, blurred vision, light sensitivity, or excessive tearing. Promptly consulting an eye doctor is essential if any of these signs appear, as they could indicate an early-stage infection.
