Optical Inserts
If you need vision correction, optical Inserts from our partners Lensabl (North America) or Lensology (Europe) may improve your experience with Spectacles. Optical inserts will be custom made with your prescription and attach to Spectacles, sitting between your eyes and the display.
Contact lens wearers should be able to use Spectacles without optical inserts.
Is my prescription eligible for optical inserts?
Supported prescription ranges are determined by “Total Power”. Spectacles support optical inserts with a range of Total Power from +1.00 to -5.00 diopters. To determine whether your prescription is supported, calculate Total Power by combining your Sphere and Cylinder values from your prescription.
Examples for how to assess your Total Power below:
| Sphere | -2.00 | +1.50 | -3.25 | -3.50 | -5.00 |
| Cylinder | -1.00 | -0.50 | +1.25 | -2.50 | -0.75 |
| Total Power | -3.00 | +1.00 | -2.00 | -6.00 | -5.75 |
From the table above, the example of -6.00 and -5.75 would fall out of the range of supported prescriptions. Note, you will only supply your prescription to Lensabl or Lensology, not the “Total power”.
For further information, and to confirm whether your prescription can be supported, please reach out to Lensabl or Lensology directly.
Fitting your Optical Insert
To use an optical insert please carefully remove the existing nose clip by pulling it directly away from the frame until it comes loose.
Feed the nose clip through the optical insert.
The optical insert (that includes a nose clip) can then be inserted by pushing it until it clicks into place.
The nose pad of the insert can then be adjusted to fit.
