It’s fairly common to feel dizzy, slightly “off,” or have a headache when you first start wearing new glasses. The adjustment time depends on what changed. Common reasons new glasses can cause dizziness * Prescription changed: Even a relatively small change in sphere, cylinder, or astigmatism

If you leave the astigmatism axis blank, what happens depends on the prescription and the ordering system: * If CYL is also blank/zero: Axis is normally not needed. The prescription is treated as having no astigmatism correction. * If CYL has a value but AXIS is blank: The prescription is incom

Yes. Glasses slipping down or sitting unevenly can create a temporary visual PD offset, especially with higher prescriptions or progressive lenses. * PD (pupillary distance) is the distance between the pupils and is independent of the frame. * If the glasses slide down, the optical centers move

Yes, incorrect PD (pupillary distance) can cause distorted or uncomfortable vision with new glasses, especially with stronger prescriptions or progressive lenses. If the PD is incorrect, the optical center of the lenses may not line up properly with your pupils. This can cause: * Blurred or d

Yes. Incorrect fitting height can make progressive lenses blurry or difficult to use for near vision. The fitting height (segment height) determines where the progressive corridor and near zone are positioned relative to your eyes. If it is wrong: * Too high: the near zone may sit too high, m

Yes—but the difference is about how the PD is measured, not necessarily the total distance between your pupils. * Binocular/total PD: One number for both eyes, e.g. 64 mm. * Monocular PD: Two separate measurements, e.g. 32 mm right + 32 mm left = 64 mm. The important point is that monocular

If you choose narrow frames while having a wide pupillary distance (PD), several issues can arise depending on how extreme the mismatch is. 1. Lens thickness may increase If your pupils are farther apart than the optical centers of the frame, the lab has to decenter the lenses outward. This c

Yes, many optical labs can process lenses with astigmatism (cylinder) greater than 4.00 D, but it depends on the lens material, design, and the lab’s capabilities. In general: * Cylinder over 4.00 D is considered a high astigmatism prescription and usually requires more specialized lens surfa

If your left-eye (OS) and right-eye (OD) prescriptions are accidentally swapped, the glasses will usually feel wrong almost immediately. What you experience depends on how different the two prescriptions are. Common symptoms include: * Blurry vision that doesn’t clear up. * Eye strain or fat

#emergingcreator Does poor lighting affect pupillary distance measurement? Yes. Poor lighting can reduce the accuracy of a pupillary distance (PD) measurement, especially if it’s being measured from a photo or with a smartphone app. Here’s why: * Pupils enlarge in dim light. When your pu

Yes. Pupillary distance (PD) measured from a selfie can be inaccurate, and the amount of error depends on how the measurement is taken. Common sources of error include: * Camera distortion: Wide-angle front cameras can distort facial proportions, especially if the phone is held close. * Incor

While you may still be able to use a two-year-old prescription, we recommend updating your prescription every year since your vision can change. A current prescription helps ensure your new glasses provide the best possible clarity and comfort. If your prescription is over two years old, it’s a goo

Yes. An incorrect pupillary distance (PD) can make new glasses feel uncomfortable or even cause dizziness, especially if the error is significant. Common symptoms of an incorrect PD include: * Dizziness or a sense of imbalance * Eye strain or fatigue * Headaches * Difficulty focusing * A
