Built for Kids Who Never
Slow Down

Don't worry — it looks more confusing than it is! Here's the quick decoder:

OD means right eye, OS means left eye. SPH (sphere) corrects nearsightedness (minus numbers) or farsightedness (plus numbers). CYL (cylinder) and AXIS correct astigmatism — if your child has it, both numbers will appear together.

Some prescriptions also include ADD (for reading power) or prism (for eye alignment). Most kids won't have these, but if yours does, just enter them exactly as written.

The most important thing: make sure your prescription is current (less than 1 year old) and comes from a licensed eye care professional. If anything looks unclear, snap a photo and send it to hi@eyebuddykids.com — we'll help you figure it out before you order.

PD stands for pupillary distance — the space between your child's pupils, measured in millimeters. It tells us exactly where to place the optical center of each lens so your child sees clearly and comfortably.

Some eye doctors include PD on the prescription, but many don't, especially for kids. If yours didn't, no problem! You have two easy options:

Option 1: Use our PD Buddy tool. It's a camera-based measurement right on our site. Just have your child sit still, look straight ahead, and follow the on-screen guide. It takes about 30 seconds.

Option 2: Call your eye doctor's office and ask. They usually have it on file even if they didn't print it.

Typical kids' PD ranges from about 43mm to 58mm depending on age. If you're unsure whether your measurement looks right, reach out to us — we double-check every order before it goes to the lab.

Size is the #1 reason online glasses don't work out — so we've made it really hard to get wrong.

Every EyeBuddy frame is organized into age groups based on lens width, the most reliable indicator of fit:

Ages 1-4: 40-44mm

Ages 5-8: 44-48mm

Ages 9-12: 48-52mm

Ages 13+: 50-54mm

The fastest way to check: look at your child's current glasses. There's usually a set of numbers printed on the inside of the temple arm. The first number is the lens width. Match that to our age groups and you're golden.

No current pair to measure? Use our Fit Guide — it walks you through finding the right size using age, face shape, and a quick reference photo. And remember, every order comes with our Perfect Fit Guarantee. If the size isn't right, we'll swap it free.

Yes. EyeBuddy frames and lens choices are built for active kids.

Polycarbonate and Trivex are impact-resistant materials. High-Index keeps stronger prescriptions thinner and lighter while staying optically balanced.

For frames, our FlexBuddies line has 180-degree flexible hinges, FeatherLite keeps weight low, and SportBuddies adds a more secure active fit.

Glasses still need care: store them in the case, clean with the microfiber cloth, and use both hands when putting them on or taking them off.

If something breaks during normal use, contact us and we will help.

Choose by prescription and daily use.

Trivex: index 1.53, high Abbe value around 43-45, crisp optics, and lighter feel.

Polycarbonate: index about 1.59, strong impact resistance, best for active kids.

High-Index: thinner and lighter for stronger prescriptions. 1.61 has Abbe ~41, 1.67 has Abbe ~32, and 1.74 has Abbe ~31.

You can also add blue-light filtering, gray photochromic lenses, or sun lenses when available. Still have questions? Email hi@eyebuddykids.com and we will help.

Kids' eyes change fast, and many vision problems show zero obvious symptoms. The American Optometric Association recommends this schedule:

First exam at 6 to 12 months old. A second exam at age 3. Another before starting school, age 5-6. Then every year after that through age 18.

Signs to watch for between checkups: sitting too close to screens or books, frequent squinting or head tilting, complaints of headaches or tired eyes, losing their place while reading, or one eye drifting inward or outward.

If your child already wears glasses, annual exams are especially important because their prescription can shift as they grow. A prescription older than one year may no longer be accurate — and we want every pair of EyeBuddies to give them their sharpest vision possible.
