Image Jump Calculator
This tool is intended for educational and dispensing support use.
It calculates image jump from the segment top to segment optical center distance and add power.
Summary Output
Enter the segment optical center distance and add power above, then submit the form.
How It Works
This calculator uses the standard image jump formula from the study guide:
Image Jump = (distance from segment top to segment O.C. in mm × Add Power) / 10
It is useful when thinking through multifocal segment design and how much jump occurs at the segment top. :contentReference[oaicite:1]{index=1}
