You must also consider whether you have anFFP (first focal plane) scopeor SFP (second focal plane) reticle. Suffice it to say, having an FFP reticle enables a shooter to use their MOA reticle effectively and accurately at any magnification. If you have an SFP scope, the MOA reticle is a...
for the progressive lens. The base design may also include a distribution of the refractive and/or astigmatic errors. The base design also preferably includes a distribution of the magnification, anamorphotic distortion, vertical and/or horizontal prism, gradient of the refractive value, and/or asti...
On the other hand, random errors may be caused by an altered corneal refractive index, mistaken detection of stromal interface, variation in magnification ratio of the posterior cornea, stromal haze, change in transparency in the early postoperative cornea, and alterations in shape reconstruction ...
