The Quick Answer
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.

| Contact Lenses | Daily, bi-weekly, or monthly depending on lens type | Lenses feel uncomfortable or dry, Vision seems blurry even with lenses in |
Why Daily, bi-weekly, or monthly depending on lens type? (The "Why It Matters")
Contact lenses accumulate protein deposits, bacteria, and debris over time. Overwearing them increases risk of serious infections like keratitis, corneal ulcers, and even permanent vision loss.
Warning Signs You Waited Too Long
If you're noticing any of these signs, it's time to take action immediately:
- Lenses feel uncomfortable or dry
- Vision seems blurry even with lenses in
- Eyes are red, irritated, or itchy
- You've exceeded the recommended wear time
Pro Tips for Success
- 1Never 'stretch' your lenses beyond their schedule
- 2Always wash hands before handling lenses
- 3Replace your lens case every 3 months
- 4Use fresh solution daily—never top off old solution

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.
