How to Use the Contact Lens Replacement Schedule
Proper contact lens replacement is critical for eye health. Even lenses that look clean accumulate protein deposits, lipids, and bacteria over time that irritate the cornea and reduce oxygen transmission.
Adding Your Lenses
Enter each eye separately (left and right) so you can track them independently — sometimes one eye goes through lenses faster if you remove one eye at a time. Enter the date you opened the current pair. The tracker calculates your replacement date and shows days remaining.
Warning Signs
Remove lenses immediately and consult an eye doctor if you experience: eye pain, redness that doesn't resolve after removing lenses, discharge or crusting, blurred vision that doesn't improve, or unusual light sensitivity. These can be signs of infection that requires prompt treatment.
Frequently Asked Questions
Is this contact lens tracker free?
Yes, completely free. Lens data is saved in your browser's local storage.
What happens if I wear contacts past their replacement date?
Wearing contacts past their replacement date significantly increases risk of eye infections, including serious bacterial keratitis. Old lenses accumulate protein deposits, bacteria, and debris that irritate the cornea and reduce oxygen transmission. Always follow your prescribed replacement schedule.
Can I sleep in contact lenses?
Most soft contact lenses are not approved for sleeping. Extended-wear lenses exist but require specific prescriptions. Sleeping in non-extended-wear contacts greatly increases infection risk. Always remove and disinfect lenses before sleeping unless specifically told otherwise by your eye doctor.
How should I clean and store contact lenses?
Use multipurpose solution to rinse and store lenses. Rub lenses gently even with no-rub solution for better cleaning. Replace your case every 1-3 months. Never use tap water, saliva, or plain saline for cleaning. Let the case air dry face-down on a clean tissue after each use.
When should I throw out a contact lens immediately?
Immediately if you have eye redness, pain, discharge, or blurred vision that doesn't clear with blinking. Also discard if the lens is torn, damaged, or if you're not sure how long it has been open.
