Broken Eyes, if you look at your spherical aberrations from your 8mm wavefront scan... please tell us how many diopters of equivalent defocus you would have from this induced HOA alone.

I would love to know.

People need to understand that these distortions ARE visually debilitating and there are no glasses to fix them.

If you add the spherical aberration and the coma in my left eye, the equivalent defocus is about 2.25 diopters.

I don't know if this is accurate or not because I'm using an 8mm scan but the forumula is for a 6mm pupil.

I don't know how to work this formula to determine the factor for an 8mm pupil.
