As contact wearers, we’re often asked how long contact lenses last. Well, it depends on various factors, but the average lifespan of contact lenses is around one year. In this article, we’ll take a closer look at what affects lens lifespan and what you can do to make your lenses last as long as possible. Keep reading for more information.
What are contact lenses made of, and how do they work?
Contact lenses are small, curved pieces of plastic that sit directly on the surface of the eye. They are usually made from a type of clear plastic called polymethyl methacrylate (PMMA). PMMA is a durable material that is also used in bulletproof glass and clear plastic surgery implants.
Contact lenses work by bending the light that enters the eye, which helps to correct vision problems. Myopia, or nearsightedness, is caused by light being bent too much as it enters the eye, while hyperopia, or farsightedness, occurs when light is not bent enough.
By correcting the way that light bends, contact lenses can help people to see more clearly. There are also special types of contact lenses that can be used to correct more serious vision problems, such as astigmatism.
The two primary types of lenses are:
- Stiff or rigid gas permeable (RGP) lenses
- Soft lenses
Most people wear soft lenses as they’re more comfortable and easier to adjust to than RGP lenses. However, RGP lenses often give you better vision.
How long do contact lenses last?
The lifespan of your contact lenses depends on several factors, including:
- The type of lens- RGP lenses usually last longer than soft lenses.
- How often do you wear them- if you wear your lenses every day, they won’t last as long as if you only wear them occasionally.
- How well you take care of them- if you clean and store your lenses properly, they’ll last longer.
How often should you replace your contact lenses?
Generally, you should replace your lenses every one to two years. However, this may vary depending on the lens type and how often you wear them. For example, if you only wear your lenses occasionally, you may be able to use the same pair for longer than if you wear them every day.
Not all contact lenses are designed to be replaced yearly, and some lenses, such as daily disposable lenses, are only meant to be worn for one day before being thrown away. If unsure how often you should replace your lenses, speak to your eye care professional for guidance.
How can you make your contact lenses last longer?
There are several things you can do to make your lenses last longer, including:
- Handle them with care- be gentle when putting in and taking out your lenses.
- Clean them properly- always clean and store your lenses according to the manufacturer’s instructions.
- Don’t wear them for too long- try limiting how long you wear your lenses daily.
If you take care of your lenses and replace them as needed, you can enjoy clear vision and comfortable wear for many years.
What are the risks associated with not replacing your contact lenses on time?
While it’s not typically harmful to wear your lenses for a few extra months or even years, it’s essential to be aware of the risks associated with doing so. These risks include:
The main risk of not replacing your lenses on time is that you may develop an eye infection. Wearing lenses for too long can also lead to irritation, redness, and discomfort. You must see your eye care professional immediately if you develop any of these symptoms. They can help to diagnose the problem and determine whether or not you need to replace your lenses.
Another risk of not replacing your lenses on time is that the vision in your affected eye may worsen. It is because the curve of your lens may change over time, which can cause refractive errors.
How can you tell if your contacts are expired or damaged beyond use?
There are many ways to tell if your contacts are expired or damaged beyond use, including:
- Check the expiration date- all contact lenses have an expiration date on the packaging. Once this date has passed, you should discard the lenses.
- Inspect the lenses- if you can see any cracks, tears, or other damage on the lens, it’s time to replace them.
- Check for integrity of the lens- if the lens is no longer round or has changed shape, it’s time to replace it.
- If your lenses are dry or uncomfortable- if your lenses feel dry or uncomfortable, it may be time to replace them.
If you’re unsure whether your lenses are expired or damaged beyond use, speak to your eye care professional for guidance.
What should you do if you accidentally damage or lose your contact lenses?
You must see your eye care professional immediately if you accidentally damage or lose your contact lenses. They can help to assess the situation and determine whether or not you need to replace your lenses.
It’s vital to be aware that losing a contact lens risks developing an eye infection. It is because the lens can act as a breeding ground for bacteria. If you develop any symptoms of an eye infection, such as redness, swelling, or pain, be sure to see your eye care professional immediately.
Contacts are a safe way to improve your vision. However, replacing them as needed is crucial to reduce the risk of developing an eye infection or other problems. If you’re unsure when to replace your lenses, speak to your eye care professional for guidance, and they can help you determine the best course of action for your individual needs.
