Understanding the importance of a valid contact lens prescription
As a contact lens wearer, you know that having the right prescription is important for clear vision and comfortable wear. Using an expired prescription, however, can lead to a host of problems, including blurry vision and potential eye damage. So, how can you determine if your contact lens prescription has expired?
Knowing when your prescription was last issued
The easiest way to determine if your contact lens prescription has expired is to know when it was last issued. In the United States, contact lens prescriptions are valid for one year from the date they were issued or as dictated by state law. This means that if it has been more than a year since you last had an eye exam and were issued a new prescription, it is likely expired.
Scheduling a comprehensive eye exam
Even if your contact lens prescription has not yet expired, it is important to schedule a comprehensive eye exam at least once a year. This exam not only ensures that your prescription is up to date, but also screens for potential eye diseases and conditions that may not have obvious symptoms.
Checking for changes in vision or comfort
If you have not reached the one-year mark since your last prescription, but are experiencing changes in vision or discomfort while wearing your contact lenses, it is important to schedule an appointment with your eye doctor. These changes may indicate a need for a new prescription or a switch to a different type of lens.
Only ordering contact lenses with a valid prescription
Finally, it is crucial to only order contact lenses with a valid prescription from a licensed eye care professional. The U.S. Food and Drug Administration (FDA) enforces strict regulations on the sale of contact lenses, requiring a valid prescription for anyone looking to purchase them. By following these regulations and only using a valid prescription, you can ensure the health and safety of your eyes.
