PDgo vs 线上配镜助手

PDgo measures your pupillary distance (PD) in seconds using your iPhone's TrueDepth camera — no ruler, no mirror, no guesswork. Most online optical stores ask for your PD when you order glasses. PDgo gives you a reliable reference number right from your phone. HOW IT WORKS 1. Align your eyes inside the on-screen guide 2. Hold still — PDgo automatically captures three rounds 3. View your result and it's saved to your records WHAT YOU GET • Total PD plus left and right monocular PD • Near PD conversion for reading distance • A confidence rating based on measurement stability • Local history — rename, search, and review your measurements anytime • Lens guidance: index, coating, and shape suggestions based on your prescription PRIVATE BY DESIGN • All measurement processing happens on your iPhone • Camera frames and depth data are never uploaded • No sign-in is required for the core measurement and Apple purchase flow • Optional WeChat sign-in on the mainland China App Store syncs existing mini-program benefits and backs up new measurement values and labels saved after sign-in. Earlier local records remain on the device. You can delete cloud records or cloud account data in the app. Photos, depth data and face data are never uploaded. REQUIREMENTS & ACCURACY PDgo requires an iPhone with Face ID (TrueDepth camera). Results are a reference for ordering eyewear and talking with your optician — for medical decisions, please rely on a professional eye exam. PRICING Unlock your result with a one-time purchase, or get unlimited measurements with a yearly plan. Prices are shown in your local currency at checkout. The yearly plan auto-renews and can be canceled anytime in your Apple ID settings. Terms of Use (EULA): https://lumaseq.com/terms.html Privacy Policy: https://lumaseq.com/privacy.html
