AR smart glasses promise a screen in your field of view, but the experience falls apart if you can't see the display clearly. For the RayNeo X3 Pro, prescription inserts snap into the frame with a Click and Fit mechanism, so you don't have to wear regular glasses underneath. Getting the order right—from your prescription details to lens coatings—saves a second round of shipping and keeps the heads-up screen sharp.
These inserts are custom-made, and a small mistake in the numbers can mean blurry text or an uncomfortable fit. The process is straightforward, but a few details are easy to overlook. Below, we walk through what you need before you order, the steps to place the order, and how to avoid common headaches.
Before You Order: RayNeo X3 Pro Prescription Inserts
Prescription inserts for the RayNeo X3 Pro use a Click and Fit attachment: align the lens carrier with the inner frame and press until it clips in. The design is model-specific—these inserts won't work with other RayNeo glasses like the V3 or Air 3. They're fabricated per order, so you'll need a current prescription from an optician, and Lensology, the official provider, ships worldwide with tracking.
The turnaround time for in-stock ULTIMA lenses is 1–3 working days, according to Lensology. More complex prescriptions or coatings may add time. Worth noting: the inserts add a bit of bulk, a trade-off the glasses themselves already confront.
About the RayNeo X3 Pro AR Glasses
The base device is the RayNeo X3 Pro AR Smart Glasses with 3500nits Global Edition, built around a micro-LED light engine and wave guides. CNET reports a 6,000-nit peak brightness, which pushes a 43-inch aerial screen right into your field of view. A Snapdragon AR1 Gen 1 chipset drives the spatial UI, and connectivity runs through USB-C. The design is noticeably bulkier than standard frames—one writer at CNET said they appeared "comically large" on an average head—but the weight comes in at about 3 ounces, which is lighter than earlier RayNeo AR models.
The international release landed in mid-May 2025, and the dual-camera setup hints at hand-tracking and AI features down the line. The extra bulk might be a deal-breaker for all-day wear, but for short productivity bursts or watching a video, the screen size is hard to match.
Step-by-Step: Ordering Your Prescription Inserts
Ordering from Lensology is a four-step process that starts with the numbers from your eye doctor and ends with a click. Take your time with the prescription entry—the numbers are small, and a missing axis value can throw the entire lens.
Step 1: Obtain Your Prescription Details
You'll need your SPH, CYL, and AXIS values for each eye. Lensology may also ask for a pupillary distance (PD) measurement, which isn't always on the prescription slip. If your optician didn't write it down, you can measure it with a ruler and a mirror, but a professional measurement is more reliable. Check the expiration date, too—prescriptions older than two years may not be accepted, and if you've noticed any change in vision, it's better to get a fresh exam before ordering.
For single-vision correction, the process is direct. Progressive lenses are possible, but the ordering form will ask for additional parameters like the ADD value. Don't guess; a wrong entry here makes the inserts unusable.
Step 2: Choose Your Lens Options
Lensology offers the ULTIMA lens material, which reduces thickness for stronger prescriptions. Standard coatings include anti-reflective and blue light filtering. The anti-reflective layer cuts down on glare from the AR display, while the blue light filter may ease eye strain during long sessions. A 1–3 working day turnaround applies to in-stock ULTIMA lenses, which is faster than most custom lens shops.
If your prescription is particularly high, the thicker lens blank might push the inserts outward. Lensology's ULTIMA material helps, but the inserts will still add some depth. That's just physics—and it's one reason the Click and Fit design is useful: you can pop them out when you're not using the AR features.
Step 3: Place Your Order
On the Lensology website, select "RayNeo X3 Pro" as the frame type. Then enter your prescription values for the right and left eyes, choose your lens material and coatings, and add to cart. The checkout page lets you upload a photo of your prescription or type it in manually. Double-check every digit before confirming—especially the AXIS values, which are easy to transpose.
Worldwide delivery is available, and Lensology provides a tracking number once the lenses ship. Shipping times vary by destination, but the production time for in-stock ULTIMA lenses is the fastest bucket. If you're ordering from outside the UK, factor in a few extra days for customs.
Step 4: Attach and Test Your Inserts
When the inserts arrive, line up the carrier with the inner frame of the X3 Pro glasses. A gentle press should click them into place. Don't force them—if they don't seat easily, check the orientation. Each lens is labeled for left and right.
Put the glasses on and look at the AR display. Text should be crisp. If it's blurry, remove the inserts and look through them at a printed page. Still blurry? The prescription might be entered incorrectly. Reach out to Lensology support; they can often recheck the numbers and advise on a replacement. A loose fit is usually a sign that the clips aren't fully engaged, so give them another firm press.
Common Ordering Mistakes to Avoid
Using an expired prescription is the top error. Your eyes change, and an old Rx won't give you the clarity you need. Similarly, entering the PD incorrectly—or leaving it out entirely—can shift the optical center, causing eyestrain and fuzziness. If your optician didn't provide a PD, ask for it; don't just guess.
Another trap: assuming the inserts will fit other RayNeo models. The X3 Pro inserts are shaped specifically for this frame, and they won't click into a V3 or Air 3. For strong prescriptions, the lens material matters. If you pick a standard-index lens for a high-power correction, the inserts may end up thick and heavy. The ULTIMA option is built for exactly that scenario.
Troubleshooting: Fit and Vision Issues
If the inserts don't click in securely, check that you're aligning the carrier with the inner groove. A small amount of resistance is normal, but the engagement should be positive. If the inserts feel loose after attachment, the clips may be bent; contact Lensology for a replacement.
Blurry vision often traces back to a data entry error. Compare the numbers on your prescription to the order confirmation. A single digit off in the CYL or AXIS fields can throw the entire lens. If the vision is clear in one eye but not the other, the problem is likely in that eye's values. Lensology support can walk you through the troubleshooting. The inserts may feel heavier than expected, especially if you're new to wearing glasses. The Click and Fit design lets you remove them when you're not using the AR display, which gives your nose a break.
Daily Use with Your Prescription Inserts
Clean the inserts with a microfiber cloth—the same one you'd use for regular glasses. Avoid paper towels or clothing, which can scratch the anti-reflective coating. When not in use, keep them in the case to prevent dust buildup and accidental drops. The inserts add a few grams and some bulk to the already large X3 Pro frame, a point CNET noted in their hands-on. The good news: the Click and Fit mechanism makes removal quick, so you can hand the glasses to someone else without them needing to see your prescription.
The AR display sits ahead of the inserts, so the digital screen remains visible and bright. You might need to adjust the brightness or text size in the settings to compensate for the additional lens in the light path. For most use cases, the inserts simply correct your vision, and the AR experience stays the same—just sharper.
