How Often Should I Change My Contact Lenses?
Follow your lens type's schedule exactly: daily disposables after one day, bi-weekly lenses every 2 weeks, and monthly lenses every 30 days. Never sleep in lenses unless approved for extended wear.

Frequently Asked Questions
Can I wear monthly contacts for 30 wears instead of 30 days?
No. The 30-day limit is calendar days from opening, not wear days. Lenses degrade whether worn or not.
What happens if I sleep in my contacts?
Sleeping in non-extended-wear contacts starves your cornea of oxygen, increasing infection risk 6-8 times.
