Colored contact lenses come in different replacement schedules, so how frequently you replace them depends on the specific lens prescribed to you. Following that schedule matters since the Food and Drug Administration (FDA) recommends discarding lenses once they reach their prescribed replacement period.
Daily colored contact lenses
Daily disposables are worn once and thrown away at the end of the day, giving you a fresh pair each time without the need to clean or store the lenses overnight.
Bi-weekly colored contact lenses
Bi-weekly lenses are reusable for about two weeks when prescribed on that schedule, so you'll need to remove, clean, disinfect, and store them properly between wears.
Monthly colored contact lenses
Monthly lenses are designed for a longer planned-replacement cycle and need regular cleaning and proper storage between uses before being discarded according to the prescribed schedule.
What to Know Before Buying Colored Contact Lenses Online
Colored contact lenses require a valid prescription, even when they have zero corrective power and are worn only to change your eye color. Your prescription should include the specific lens brand and measurements your eye care professional determined during your fitting, since contact lenses aren't interchangeable based on power alone.
When ordering online, use a seller that asks for your prescription or verifies it with your eye care provider before dispensing the lenses. Under the Federal Trade Commission (FTC) Contact Lens Rule, sellers must have a copy of a valid prescription or complete the required verification process, and they can't substitute a different brand unless permitted under the prescription rules.
