What's happen with PALs when the frame is not in the right position of wear ?
- CVD = Corneal Vertex Distance
- PT = Pantoscopic Tilt Angle
- FFA = Face Form Angle
1. One wearer with Premium PALs in four frames = 4 diffiference vision field.
2. Three wearers with Premium PALs in one frame = 3 difference visual field.
3. One wearer with Impression ILT in four frames = same visual field.
Tell me if you like some more! :bbg:
