Buying prescription glasses online can feel confusing if you don’t understand your prescription. Have you ever looked at your slip from the optician and wondered, “What do all these numbers and abbreviations even mean?” If so, you’re not alone.
In this guide, we’ll walk you through how to read your glasses prescription, explain what each section means, and show you how to use this knowledge when shopping online at Reflexa. By the end, you’ll feel confident choosing the perfect pair of frames that fit your vision needs and your style.
Why Understanding Your Glasses Prescription Matters
Your glasses prescription is more than just numbers—it’s the roadmap to clear vision. Whether you’re nearsighted, farsighted, or have astigmatism, knowing how to read your prescription helps you:
- Order prescription glasses online with ease.
- Avoid mistakes when entering your details during checkout.
- Make sense of your options, from men’s prescription glasses to women’s eyewear.
- Understand whether your prescription applies to contacts, safety glasses, or even stylish sunglasses.
Breaking Down Your Glasses Prescription
Most prescriptions include the following elements. Let’s break each one down in simple terms.
SPH (Sphere)
- Indicates if you’re nearsighted (–) or farsighted (+).
- The higher the number, the stronger your lenses need to be.
CYL (Cylinder)
- Shows the amount of correction for astigmatism.
- If blank, you don’t need this adjustment.
AXIS
- Works with CYL to correct astigmatism.
- It’s measured in degrees, showing where the correction is needed.
ADD
- Stands for “Addition.”
- It’s for reading or multifocal lenses, giving extra help up close.
PD (Pupillary Distance)
- The distance between your pupils, in millimeters.
- Ensures your lenses line up perfectly with your eyes.
Common Questions About Glasses Prescriptions
You might see different terms or wonder how your prescription relates to other eyewear. Let’s clear up a few common questions.
Is your contact lens prescription the same as glasses?
No. Contacts sit directly on your eye, so the measurements differ. You’ll need a separate contact lens prescription.
How to tell if your glasses prescription is wrong?
If you experience frequent headaches, blurry vision, or dizziness with new glasses, your prescription may need adjusting.
How long do glasses prescriptions last?
In Trinidad and Tobago, most prescriptions are valid for one to two years. Regular eye exams ensure your vision stays up to date.
What to do with old prescription glasses?
Consider donating them to local charities or recycling programs—they can make a difference for someone in need.
