When to Replace Your Contact Lenses

A lady choosing whether or not to replace her contact lenses.

Table of Contents

Replacing contact lenses on time helps maintain comfort and clarity. A lens gradually collects deposits and becomes less smooth, which can lead to irritation or haze. Each lens type follows a specific schedule based on the day it was opened.

Replacement Schedules by Lens Type

Daily Disposables

Worn once and discarded the same day. No cleaning or storage involved.

Biweekly Lenses

Good for 14 days after opening. Even with light use, they should be replaced at the two-week mark.

Monthly Lenses

Intended for 30 days once opened. Pushing them beyond this period increases discomfort.

Checklist: Signs It’s Time for a New Pair

  • The replacement date has passed.
  • The lens feels dry or gritty during wear.
  • Vision looks slightly hazy or inconsistent.
  • Cleaning no longer restores a smooth surface.
  • You slept in your lenses and want to avoid irritation.
  • You recently recovered from an eye infection.
  • The lens case or solution came into contact with water or expired solution.
