Thanks for the video. Although my preference is different;
I work with the +1.50 D lens and use the other lens(es) ON this one as needed. By this way, I don't have to re-calculate the absolute value, as the OTHER (2nd) lens is the exact number of the correction. Additionaly, if there is astigmatism, I put the THIRD lens on the right axis. ex: +1.5 (working lens) with -2.0 and +1.50 x 90; answer is -2.0, +1.5 x 90
In astigmatism, use of the THIRD lens on BOTH lenses eliminates the aberrations.
The problem with this example is that, when the light shines, the pupil constricts and gets so small it is difficult to see any red. Maybe thats because im just using a basic pen light
