Thanks for sharing the formula.
I will try it and let here know.

Actual thickness also changes.
OptiCampus has the option to use manual BC, otherwise it uses appropriate BC with Automatic options.

I am using below generally accepted formula for lens thickness calculation:

Thickness = MinimumThickness + ( ( ((ED+A+DBL-PD)/2)^2 x |Sph+(Cyl x sin(Axis)^2)| ) / (2000*(Index - 1)]) )

This...

I am using below formula for lens thickness calculation and then comparing my results with OptiCampus calculator:

Thickness = MinimumThickness + ( ( ((ED+A+DBL-PD)/2)^2 x |Sph+(Cyl x...

Any chance I can get that formula?

OD Sph = -7.00
OD Cyl = -3.00
OD Axis = 30
OS Sph = -4.00
OS Cyl = 0
OS Axis = 0
Reading Level Distance(mm) = 10.0
