Have you ever wondered how long your eyeglass prescription is good for? It’s a question that many people tend to overlook, but the answer can have a big impact on your vision and wallet. By knowing how long your prescription is valid, you can avoid paying for unnecessary eye exams or purchasing new glasses when you don’t need to. So, let’s answer the question – how long is my eyeglass prescription good for?
Firstly, it’s important to note that the lifespan of your prescription can depend on a variety of factors including your individual eye health and the strength of your prescription. Typically, however, eyeglass prescriptions are valid for anywhere from one to two years. This means that if you haven’t had an eye exam in over a year, it’s time to schedule one. It’s also worth noting that if you have any changes in your vision or eye health during that one to two year period, you should consult with your eye doctor to determine if a new prescription is necessary.
Now that we know how long eyeglass prescriptions are valid for, let’s talk about why it’s important to stay up to date on them. Wearing an outdated prescription can lead to a variety of problems including headaches, blurry vision, and even increased eye strain. Additionally, if your prescription is significantly off, it can be dangerous to perform certain tasks such as driving or operating heavy machinery. By ensuring that your prescription is up to date, you can avoid these issues and ensure your vision is always at its best. So, if you’re due for an eye exam or aren’t sure if your current prescription is valid, take the time to schedule an appointment with your optometrist today.
What is an eyeglass prescription?
An eyeglass prescription is a written document from an eye doctor that specifies the type and amount of corrections needed for your vision. It is the blueprint for creating eyeglasses tailored to your specific needs. The prescription includes information such as the power of the lenses, the axis of astigmatism, and the distance between pupils. It’s important to have an up-to-date prescription to ensure that your eyeglasses provide clear and comfortable vision.
How is an eyeglass prescription determined by an optometrist?
When you visit an optometrist, they will conduct a comprehensive eye examination to assess your vision and determine whether you need glasses or contact lenses. The examination may take up to an hour to complete, and it involves several tests to measure your visual acuity, eye coordination, and eye health.
- The optometrist will begin by asking you to read letters on a chart to determine the clarity of your vision. This test is known as a visual acuity test.
- They will also examine your eye coordination to ensure that your eyes are working together and focusing properly. This test may involve covering one eye and then the other while looking at a target.
- The optometrist will check the internal and external structures of your eye to assess your eye health and screen for any eye diseases or conditions.
Based on the results of the eye examination, the optometrist will then determine the type of correction you need for your vision. If you are nearsighted, your prescription will have a negative number, while if you are farsighted, your prescription will have a positive number. The prescription will also include a number for astigmatism, which measures the degree of irregularity in the curvature of your cornea.
The prescription will typically include three numbers for each eye, which represent the following:
| Number | Definition |
|---|---|
| 1 | Sphere (SPH): This indicates the degree of nearsightedness or farsightedness, with a negative number indicating nearsightedness and a positive number indicating farsightedness. |
| 2 | Cylinder (CYL): This measures the degree of astigmatism, with a number indicating the amount of correction needed. |
| 3 | Axis: This indicates the orientation of the astigmatism correction needed, ranging from 0 to 180 degrees. |
Once you have your prescription, it is important to get it filled and update your eyeglasses or contact lenses as needed. Your prescription is typically valid for one to two years, depending on your age and overall eye health. Be sure to schedule regular eye examinations with your optometrist to ensure that your prescription is up to date and your eyes are healthy.
What is the average expiration date for an eyeglass prescription?
It is important to know how long your eyeglass prescription is valid for because the prescription determines the level of correction needed for your vision. Typically, an eyeglass prescription is valid for one to two years, depending on the optometrist or ophthalmologist who issued the prescription.
- Some eye doctors may prescribe eyeglasses for a shorter period of time, such as six months.
- Other eye doctors may prescribe eyeglasses for a longer period of time, such as three years.
- It is worth noting that some insurance companies may have their own rules about how long an eyeglass prescription is valid for.
Eye doctors determine the expiration date of an eyeglass prescription based on various factors, such as the patient’s age, the severity of their refractive error, and any changes in their eyesight since their last appointment.
It is important to keep in mind that even if your prescription has not yet expired, you may still need to schedule a new eye exam if you are experiencing issues with your vision. Your eye doctor will be able to determine if any adjustments are needed to your prescription to provide the best vision correction for your eyes.
Factors that may impact the duration of an eyeglass prescription
The expiration date of an eyeglass prescription may vary depending on certain factors. These include:
- The patient’s age. Younger patients may need to have their eyes checked more frequently than older patients, as their vision can change more rapidly.
- The patient’s health. Certain health conditions, such as diabetes or high blood pressure, can affect a patient’s eyesight and may require more frequent check-ups.
- The severity of the patient’s refractive error. Patients with a higher degree of nearsightedness, farsightedness, or astigmatism may need to see their eye doctor more often than those with a milder refractive error.
Table: Eyeglass prescription expiration dates
| Optometrist/ Ophthalmologist | Expiration Date |
|---|---|
| Most optometrists | 1-2 years |
| Some optometrists | 6 months |
| Some ophthalmologists | 3 years |
It is important to check with your eye doctor and insurance provider to determine how long your eyeglass prescription is valid for. By scheduling regular eye exams and following your eye doctor’s recommended timeline for check-ups, you can ensure that your prescription is accurate and up to date.
Can an expired eyeglass prescription be renewed?
As with any medication, eyeglass prescriptions have an expiration date. The standard duration of an eyeglass prescription in the United States is two years for adults under 65 and one year for adults 65 and older. However, the specific length of time your eyeglass prescription is valid may vary based on your individual needs and the discretion of your eye doctor.
If your prescription has expired and you need new glasses or contacts, you may wonder if it’s possible to renew an old prescription instead of getting a new one. The answer is no. According to the American Optometric Association, eyeglass prescriptions must be current to ensure that you’re wearing appropriate corrective lenses for your current visual needs, and to minimize any potential harm from wearing an outdated prescription.
Why can’t an expired eyeglass prescription be renewed?
- An outdated prescription may not be accurate, meaning that it won’t provide the right level of correction for your eyesight.
- Your eyesight may have changed since you last had an eye exam, so you need to be assessed again to determine the correct prescription.
- Wearing the wrong prescription can actually cause headaches, eye strain, and even increased myopia, so it’s important to ensure that your prescription is up-to-date.
What should you do if your eyeglass prescription has expired?
If your prescription has expired, the only way to get a new one is to schedule an eye examination with an optometrist or ophthalmologist. Your doctor will assess your eyesight and determine your current eyeglass prescription. Even if your eyesight feels fine, it’s essential to have regular eye exams to ensure that your visual health is in good condition.
Conclusion
Ultimately, an expired eyeglass prescription cannot be renewed. You need to schedule a new eye exam to ensure that you are wearing the right prescription for your current visual needs. If you experience any changes in your eyesight or notice any issues with your vision, schedule an appointment with your eye doctor as soon as possible to avoid any potential complications. Your eyes are precious, and taking care of them by ensuring you have up-to-date eyeglass prescriptions is crucial for your overall health and wellbeing.

| North America | USA, Canada | Two years (adults under 65), One year (adults 65 and over) |
| Europe | EU Member States | One to two years (depending on the country) |
| Asia | China, Japan, South Korea | One year |
It’s important to note that the duration of validity may vary based on individual needs and the discretion of the prescribing doctor.
Are there different expiration dates for different types of eyeglass prescriptions (single vision vs. progressive lenses)?
Eye prescriptions are fundamental pieces of document that people carry around when buying eyeglasses or contact lenses. They are statements from optometrists of what your eye needs to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Notably, the lifespan of the prescription varies depending on the type.
- A single vision prescription for nearsightedness or farsightedness is valid for up to two years before requiring updating. This is because the eye changes over time, especially for individuals in their twenties.
- A prescription for reading glasses also has a lifespan of two years, just like single vision prescriptions.
- On the other hand, a progressive lens prescription, which is suitable for individuals who need different power for viewing distances, expires after one year. This is because progressive lenses require particular measurements that vary with the wearer’s specific life stage and head placement. Therefore, prescriptions for progressive lenses require frequent modification.
It is worth noting that while these timings are standard, you can always check with your optometrist to see if they have different advice based on your personal eye needs. It is also important to understand that if you are experiencing a significant change in vision before your prescription expires, you should visit your optometrist to get an updated prescription.
Conclusion
In conclusion, eyeglass prescription lifespan varies depending on the type. Single vision and reading glasses prescriptions are valid for up to two years, while progressive lens prescription requires updating every year. It is always best to consult with your eye doctor for more specific guidelines based on your needs.
| Type of Prescription | Expiration Date |
|---|---|
| Single Vision | Up to two years |
| Reading Glasses | Up to two years |
| Progressive Lenses | Requires updating every year |
Overall, ensuring your prescription is up-to-date is crucial to maintaining good eye health and ensuring that you are getting the most out of your eyeglasses or contact lenses.
What happens if I try to use an expired eyeglass prescription?
As we previously discussed, eyeglass prescriptions are only valid for a certain period, usually one or two years. If you try to use an expired prescription to order new glasses, you may face a few problems:
- The prescription may no longer be accurate: Your vision can change over time, so an expired prescription may not have the correct measurements for your current needs. This can result in uncomfortable glasses or poor vision.
- The eyewear provider may refuse to fill the order: Many eyewear providers require a current prescription before they can fulfill an order. This is to ensure that the customer is receiving the most accurate and up-to-date correction for their vision.
- Your insurance may not cover the order: Some insurance plans require a current prescription in order for the customer to receive coverage for their eyewear. If you are using an expired prescription, you may not be able to take advantage of your vision benefits.
To avoid these issues, it’s best to schedule regular eye exams and obtain a new prescription as needed. This will ensure that you are always seeing as clearly as possible and that your glasses are comfortable and effective.
How long is my eyeglass prescription good for?
Eyeglass prescriptions typically expire after one or two years, depending on the state and the eye doctor. The expiration date is determined by the doctor’s professional judgement and depends on factors such as the patient’s age, overall health, and visual history.
For example, a patient with a history of rapid vision changes may be given a prescription that is only valid for six months, while a patient with stable vision may be given a prescription that is valid for two years. Additionally, some states require prescriptions to be valid for a certain period, regardless of the individual patient’s needs.
What is included in an eyeglass prescription?
An eyeglass prescription typically includes the following information:
| Measurement | Description |
|---|---|
| OD and OS | These stand for “oculus dexter” (right eye) and “oculus sinister” (left eye) and indicate the prescription strength for each eye. |
| Sphere | This number indicates the strength of the lens needed to correct nearsightedness or farsightedness. A positive number indicates farsightedness, while a negative number indicates nearsightedness. |
| Cylinder | This number indicates the strength of the lens needed to correct astigmatism. |
| Axis | This number indicates the angle of the astigmatism correction. |
| Add | This number indicates the strength of the lens needed for close-up tasks like reading. It is usually only included for patients over 40. |
It’s important to note that your prescription may also include additional notes or details specific to your vision needs, such as prism measurements or bipolar distance.
Does insurance coverage for eyeglasses depend on the expiration date of the prescription?
Insurance coverage for eyeglasses can be a complex subject. When it comes to the expiration date of your prescription, there are a few things to consider.
- Insurance companies may have their own policies on how often you can have your vision checked and your prescription updated. Some plans may allow for an annual exam and new prescription, while others may only cover these services every two years.
- Depending on your insurance plan, coverage for eyeglasses may only be included if you have a valid prescription. In this case, you may need to pay out of pocket for new glasses if your prescription has expired.
- Some insurance plans may offer coverage for eyeglasses with an expired prescription, but only if the prescription is less than a certain number of years old – typically one or two.
It is important to check with your insurance provider to understand what your specific policy covers and how often you can have your prescription updated. If your coverage does not include glasses with an expired prescription, it may be worth considering vision insurance or discount programs to help offset the cost of new glasses.
Additional considerations
Even if your insurance plan does not cover glasses with an expired prescription, it is important to remember that vision can change over time. Regular eye exams and updated prescriptions can help ensure that you are seeing as clearly as possible and that your eye health is being monitored.
If you are experiencing changes in your vision or notice any issues with your eyes, it is important to schedule an appointment with your eye doctor as soon as possible.
Table: Insurance coverage for eyeglasses with expired prescriptions
| Insurance provider | Expired prescription coverage |
|---|---|
| ABC Insurance | Less than 1 year |
| XYZ Insurance | Less than 2 years |
| 123 Insurance | No coverage for expired prescriptions |
It is important to note that insurance coverage can vary greatly between providers and plans. Always refer to your specific policy to understand what is covered and what may require out-of-pocket expenses.
Can I order new glasses online with an expired prescription?
When it comes to ordering new glasses online, many people wonder if it’s possible to do so with an expired prescription. The short answer is no, you cannot legally buy new glasses or contacts with an expired prescription.
- Your eyeglass prescription is only valid for a certain amount of time, and once it expires, you need to schedule another eye exam to update your prescription.
- There are several reasons why eyeglass prescriptions expire, including changes in your eye health, changes in your vision, and changes in the strength of your corrective lenses.
- While it may be tempting to order new glasses online using an expired prescription, doing so can be dangerous for your eye health, and it’s simply not worth the risk.
But what if you don’t have time to schedule an eye exam or you simply don’t want to pay for another one? Fortunately, there are a few ways to get around this issue.
If your prescription is only slightly expired (within a few months), some online retailers may allow you to order new glasses or contacts with your old prescription. However, this is not a guarantee, and it’s important to check with the retailer first to ensure that they are willing to accept your expired prescription.
Another option is to visit your eye doctor and ask for a copy of your old prescription. While it may be expired, having a copy of the prescription can still be helpful when ordering new glasses online, as it can provide important information such as your lens strength and other measurements.

|---|---|
| 1 year | Alabama, Colorado, Connecticut, Hawaii, Idaho, Indiana, Iowa, Kansas, Maine, Massachusetts, Mississippi, Montana, Nebraska, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Rhode Island, South Carolina, Vermont, Virginia, Washington |
| 2 years | Arizona, Arkansas, Delaware, Florida, Georgia, Illinois, Kentucky, Louisiana, Maryland, Michigan, Missouri, New York, Pennsylvania, West Virginia |
| 3 years | Alaska, California, Minnesota, Nevada, South Dakota, Texas, Utah, Wisconsin, Wyoming |
Ultimately, the best course of action when it comes to ordering new glasses online is to keep your prescription up to date. This not only ensures that your glasses are providing you with the best possible vision, but it also helps to protect your overall eye health.
How often should I have an eye exam to update my eyeglass prescription?
Having your eyes examined regularly is crucial to maintaining good eye health and ensuring that your eyeglass prescription is up-to-date. How often you should have an eye exam depends on your age, overall health, and risk factors for eye conditions. Typically, the following guidelines apply:
- Children under the age of 5 should have their eyes examined at least once by age 3.
- Children ages 6 to 18 should have their eyes examined every two years, or as recommended by their optometrist or ophthalmologist.
- Adults ages 19 to 60 should have their eyes examined at least once every two years, or as recommended by their optometrist or ophthalmologist.
- Adults over the age of 60 should have their eyes examined annually, as they are at increased risk for age-related eye conditions such as cataracts, macular degeneration, and glaucoma.
If you have a personal or family history of eye conditions, such as glaucoma or macular degeneration, or have a chronic medical condition such as diabetes, you may need to have more frequent eye exams to monitor your eye health.
It’s important to note that even if you have 20/20 vision and don’t wear glasses or contacts, you should still have regular eye exams. Eye exams can detect a variety of eye conditions and diseases that may not present symptoms until they have progressed to a more serious stage.
By following these guidelines and scheduling regular eye exams, you can ensure that your eyeglass prescription is up-to-date and maintain good eye health.
Are there any exceptions to the expiration date rule for eyeglass prescriptions (e.g. military personnel, certain medical conditions)?
Normally, an eyeglass prescription is valid for one to two years, depending on the state or country’s regulations. However, certain medical conditions or circumstances can affect the expiration date.
- Military personnel: Active-duty military personnel who need glasses or contact lenses for their job are exempt from the expiration date rule. Their prescription is valid for as long as they remain in service.
- Medical conditions: Individuals with certain medical conditions that affect their eyesight may need more frequent prescription updates. This includes patients with diabetes, glaucoma, and other eye diseases that require monitoring.
- Change in prescription: If a patient experiences a significant change in their vision, they may need a new prescription even if their old one has not expired yet.
It’s important for patients to follow their optometrist’s advice regarding the expiration date of their eyeglass prescription. Even if the prescription is still valid, it may not provide the best possible vision correction if the patient’s eyesight has changed significantly.
Below is a table showing the expiration date of eyeglass prescriptions in different states in the US:
| State | Expiration date |

| Alabama | 2 years |
| Alaska | 1 year |
| Arizona | 5 years |
