A guide to
Your prescription
After an eye exam, your optician gives you a prescription for you to use when ordering your unique opticals. Understanding this prescription helps you get the perfect lenses for clear vision. Here's a guide to help you decode it:
Sphere (SPH):
Negative (-): You are nearsighted, meaning you see things better up close.
Positive (+): You are farsighted, meaning you see things better far away.
Cylinder (CYL): If you have astigmatism, this number shows how much correction your lenses need to make your vision sharp and clear.
Axis: This number (from 1 to 180) tells you the direction to place the astigmatism correction in your lenses.
Pupillary Distance (PD): This is the distance between your pupils, measured in millimeters. It ensures your lenses are perfectly aligned with your eyes for the best vision.
Your prescription is unique to you. It's like a special recipe that helps create lenses just for your eyes, giving you the clearest vision possible. When you order opticals online at BERTA, these numbers help us make sure your lenses fit your needs perfectly.
If you have any questions or need help, our customer support team is always here for you. We want to make sure you have the best experience and the clearest vision with your new opticals!
