Can Daily Contact Lenses be Reused?

Contact lenses can become a bit pricey, especially daily disposable lenses, which need to be constantly replaced. This leads to the question: Can daily contact lenses be reused instead of being tossed at the end of the day? The short answer is no. The longer answer is that this is an extremely risky behaviour that can cause severe complications.

Reusing Contact Lenses

The main reason reusable contact lenses are preferred by some is that it means you need to buy fewer sets of lenses, which, over extended periods of time, can save no small amount of money. However, you need to be careful to only reuse contact lenses which are meant to be reused, or you risk potential eye irritation, infection, or worse.

Some of the risks associated with reusing daily disposable contact lenses include:

  • Increased risk of infection: When you reuse daily disposable contact lenses, you increase the risk of developing an eye infection. This is because the lenses may harbor bacteria and other microorganisms that can cause infections.
  • Dryness and discomfort: Reusing daily disposable contact lenses can lead to dryness and discomfort, as the lenses may not fit as well and may not allow as much oxygen to reach the surface of the eye.
  • Damage to the lenses: Reusing daily disposable contact lenses can cause the lenses to become damaged, which can make them uncomfortable to wear and may increase the risk of eye irritation.
  • Reduced visual clarity: Reusing daily disposable contact lenses can lead to reduced visual clarity because the lenses may become dirty or scratched over time.
  • Increased risk of scratching your eye (corneal abrasion): If your contact lenses become damaged, they may not fit properly on the surface of your eye and could potentially cause discomfort or injury. If the lenses shift or move, they may not conform to the shape of your cornea (the front of your eye), which can cause irritation or other issues. In some cases, damaged contact lenses may even break into fragments while in the eye, which can be difficult to remove and may cause a painful scratch on the cornea (called a corneal abrasion). If this occurs, it is important to seek emergency treatment to address the issue.
  • Increased risk of corneal neovascularization: Using daily disposable contact lenses beyond their intended lifespan can reduce the quality of the lenses and impact their ability to allow oxygen to pass through to the surface of the eye. When the cornea does not receive enough oxygen (a condition called hypoxia), it may start to swell over time due to the growth of new blood vessels (neovascularization) in an attempt to increase oxygen supply. If this swelling becomes severe, it can lead to vision loss and even blindness.

What are Daily Disposable Contacts

Daily disposable lenses are lenses that you throw away in the trash at the end of the day after wearing them. After waking up in the morning, you open another pack of lenses. You won't have to clean or store daily lenses for next time if you choose daily lenses. These lenses are extremely thin, allow a lot of oxygen through to the eye, and contain a lot of water. The downside is that if you took them off in the middle of the day, they'd no longer be usable and you'd have to use a new pair.

Dangers of Cleaning and Reusing Lenses Improperly

Daily disposable contacts are ultra-thin, so cleaning them is ineffective-and it can actually break down the lens, increasing its chances of breaking during use. Think of it like this: a daily disposable lens is like a paper plate. The thin paper plates are great for one meal, but they easily absorb food particles and liquids (just like disposable lenses).

In a study conducted at Hong Kong Polytechnic University, disposable lenses were tested for bacteria after being worn for a day. Approximately 95% of the study participants had at least one pair of used lenses that was contaminated with harmful bacteria. In some cases, the harmful bacteria that grow on disposable lenses can cause severe side effects, including vision loss.

If you wear contact lenses, follow our eye doctor’s instructions about how often to change and replace them. Make sure your hands are clean before you touch the contacts or your eyes, and dispose of the contacts properly. Don't extend the use of your contacts beyond their set schedules. It will ensure that your eyes are in the best possible health.

Common Questions

The duration can range from eight to 16 hours a day. It depends on your eyesight, how well you tolerate contacts, and whether or not you suffer from dry eyes. Never wear the lenses for longer than recommended by the manufacturer and our eye doctor. If you have sensitive eyes or work long hours, you might need a backup pair of glasses for taking out your daily lenses after eight hours. The length of time you can wear your lenses each day will be determined by our eye doctor.

I haven't actually used the optometrist side, so my review is limited to the vision therapy offered.  This office was recommended by my occupational therapist for the treatment of my double vision following a stroke.

Love this location. I had a brain injury accident from day one one. All the team make you feel you still important and hope in the horizon after when the medical system fell you miserably. Dr. Ikeda very professional and very understanding about your issue. Two tombs up.

My husband and I were immediately impressed with Dr Ikeda. I was hit by a car while cycling which caused broken bones and three brain injuries. The brain injuries caused double vision. Dr. Ikeda examined my eyes and got me started on vision therapy with his occupational therapist who specializes in vision therapy.  She (Chris) is absolutely great.  I am impressed with the array of tools used to help recover my binocular vision.  I am doing things I never thought were possible (balance boards etc).  Chris pushes me and keeps me motivated. I really enjoy my sessions with her.  The office staff is always friendly and they have a wonderful appointment reminder tool that makes it easy to keep my calendar up to date. I am happy the rehab center at Little Co. of Mary recommended them!!

The Vision Therapy is handled in a separate office through a different door from the shared waiting room. Chris, the vision therapist, has a wide and varied assortment of tools, equipment and resources to best evaluate and treat most vision issues. After just a few visits, my double vision became easier to control, using exercises developed during the therapy process. It was time well-spent.

I have been coming here since I can remember. I love it here. The staff is so amazing and nice. They explain everything they gonna do and never make you feel rushed. Dr. Ikeda has always been my doctor and I would never want another one. He is the doctor for my whole family and is always asking how everyone is doing. I am also so crazy about picking out my frames and have to try so many and each person who helps me take the time and lets me try them all on. I would never want to go anywhere else! I definitely would recommend this office to anyone looking for a great eye doctor.

This is not for the eye exam but for the frames selection portion. I brought my prescription from Kaiser here with my VSP insurance. The reception staff was very polite and professional.  Manny helped me to pick out frames and explain my coverage.  Very helpful and patient not like the individual at the other place I rated here on Yelp.  I was running late and he still helped me and was not bothered at all.  I am so glad I came here ..........very pleased.

Very professional staff and pleasant.
