FAQs: How Long Do Contact Lenses Last? And Other Common Questions Answered
Contact lenses are a simple and budget-friendly way to see clearly without having to wear glasses. They’re perfect for anyone who likes how they look without frames or wants something a bit more practical—especially if you’re always on the go.
If you're new to contacts or just curious, you probably have a few questions like: How long do they last? What are they made of? And what’s the deal with disposable ones?
Don’t worry—we’ve got you! In this article, we’ll cover all the basics so you’ll feel comfortable and confident giving contact lenses a try.
How Long Do Contact Lenses Last?
The lifespan of contact lenses depends on the type you use. All lenses must eventually be discarded or recycled after a set period, as per your optometrist’s instructions.
Some lenses are designed to last for just one day, while others can be worn for up to two weeks or a month before needing to be replaced.
Soft disposable lenses are the most popular choice due to their convenience and comfort. The exact duration will vary depending on the brand and your individual prescription needs, but your optometrist will provide guidance based on what suits you best.
What Are Contact Lenses Made From?
Contact lenses are small, flexible discs made from soft, oxygen-permeable plastics that sit directly on the cornea of your eye. Not only do they correct your vision, but they also allow essential oxygen to reach the surface of your eye.
Most soft lenses are made from a hydrophilic (water-loving) plastic that remains soft in a moist environment. Many also include silicone hydrogel materials, which further enhance oxygen flow to the eye, promoting greater comfort for longer wear.
To prevent them from drying out and becoming unusable, contact lenses must be stored in a special solution when not being worn. While you’re wearing them, your natural tears keep them moist and flexible.
What Are Disposable Contact Lenses?
Disposable contact lenses are soft lenses designed to be worn for a set period and then thrown away. They’re a hygienic and hassle-free option, ideal for busy lifestyles.
There are three main types of disposable soft contact lenses:
- Daily Disposables:
Worn once and then discarded at the end of the day. Each morning, you open a fresh pair—no cleaning, no storage—making them the most convenient and hygienic choice.
- Fortnightly or Monthly Disposables:
These lenses are worn during the day, removed at night, and stored in a cleaning solution. Depending on the brand and your optometrist’s advice, they can be replaced every two weeks or once a month.
- Extended-Wear Lenses:
Some soft lenses are approved for continuous wear, meaning you can wear them while sleeping for up to several days or a week. However, this option should only be used under close supervision from your optometrist to ensure your eye health is maintained.
Your optometrist will recommend the best type based on your eyes, lifestyle, and preferences.
How Do I Care for My Contact Lenses?
Caring for contact lenses is straightforward but important. When not being worn, lenses should be stored in a contact lens solution. This solution contains ingredients that disinfect the lenses, remove debris, and keep them hydrated.
The best solution for you will depend on the type of lenses you use and your optometrist’s recommendation. Generally, you should also gently rub your lenses with the solution before storing them, as this helps to further remove any surface deposits.
Be sure to follow your optometrist’s advice closely to keep your eyes healthy and your lenses in good condition.
How Do I Start Using Contact Lenses?
Most people who require vision correction are suitable candidates for contact lenses. If you're interested, simply speak to your optometrist during your next eye exam. They will advise on the best type of lens based on your vision needs, eye health, and lifestyle.
It’s important to note that your contact lens prescription will differ slightly from your glasses prescription. Your optometrist will explain the difference and help you order the correct lenses.
Many optometrists also offer free trial lenses so you can test them out and learn how to insert and remove them properly. It might take a little practice, but with the right guidance, you'll soon feel confident.
