It may seem a little inconvenient to have to schedule an eye exam each year just to renew your contact lens prescription. Maybe you're even asking yourself, "Can you buy contacts with an expired prescription?". Well, there's a good reason why you can't buy contact lenses with expired prescriptions!
In the United States, you need to provide a valid prescription written by your optometrist or ophthalmologist to purchase contact lenses, since your prescription will be verified upon sale of the contact lenses. Note, this is true even for colored contact lenses without vision correction in order to ensure the health of your eyes and your vision.
Why do you need a prescription?
The reason why contact lens prescriptions expire is to protect your vision and eye health. Our eyes change over time, as does your vision, meaning that prescriptions become inaccurate over time and are no longer sufficient to correct your vision. When using lenses with an inaccurate prescription, your eyes can become strained and make your vision worse, not to mention give you headaches and blurry vision.
Contact lenses with expired prescription: yes or no?
How long do contact prescriptions last? Typically, your contact lens prescription will expire after one year from your eye examination. This is because when you consistently wear contact lenses, your eyes need to be examined annually to make sure the lenses aren't increasing your risk of eye infections or hurting the eye.
That's why we suggest that you see your eye doctor on a yearly basis to get your contacts prescription renewal and make sure your prescription is up to date and you are using the best contact lenses to meet your specific needs. Don't try to buy contact lenses online with an expired prescription, it's illegal to sell anyone contact lenses without a valid prescription.
So, check your contact lens prescription right now. If they're close to or past the expiration date, contact your eye doctor and schedule an eye exam.
