If you're planning to custom a new pair of prescription glasses, it's a convenient way to get prescription from exsiting glasses you're wearing. While using your existing vision prescription makes things easier, vision prescriptions can change over time and due to lifestyle habits, so it is best to make an appointment with an optometrist to re-examine and determine the changes necessary to make your prescriptions more accurate.


To obtain an accurate vision prescription when refitting eyeglasses, you will need to do the following:

Check existing prescription

The optometrist will usually keep your prescription on the form when you get your first prescription. The optometrist may not give you a prescription, but it is better to let the optometrist show the prescription form for you when you first get glasses out of concern for your eyesight. In this way, we can get a prescription from existing glasses when we need to get glasses again.


Look at the prescription label on the inside of one of the temples of the glasses. There are usually lens width, bridge width, and temple length, usually in mm. Having these three value pairs will help you choose the frame size.

Verify prescription

There are two ways to verify the prescription. One is to download the smartphone application test at home. Of course, this has certain requirements for equipment and operation steps. But prescriptions obtained in this way may not be very accurate.

The other is to contact your original optometrist to have your prescription verified by checking your vision and making any necessary adjustments to your glasses.


Make an appointment with an optometrist

Contact your optometrist and schedule an appointment. Explain that you want to get prescriptions for pre-existing eyes and want help from them. Be sure to bring your existing glasses to your appointment so your optometrist can use them to determine your prescription.

Once your optometrist has verified your prescription, they will give you a new prescription that you can use to buy new eyeglasses or contact lenses.


Getting a prescription from your existing glasses is a convenient and efficient way to get a new prescription. But prescriptions for glasses can become inaccurate over time. By following these steps, the prescription can be verified and confirmed in time, and the glasses can be re-refitted, so that the normal work and life will not be affected.
