Currently, there are some limitations to the types of prescription lenses that XanderGlasses can accommodate, these include prisms, progressives, (+) SPHERE corrections for distance.
Unfortunately, we are unable to manufacture lenses that require prisms, progressives, or (+) SPHERE corrections for distance vision. We have been working with the lens manufacturer to try to ease this limitation, but due to the nature of how the glasses lenses and frames are constructed, combined with the physical shape required to correct for farsightedness, we have been unable to support this combination.
You may wish to continue without prescription lenses, but we would not recommend it. While you may be able to read the captions, your vision would be blurred without a proper prescription correction, which could lead to eye strain and discomfort.
