it´s been some time since I posted my introduction, but I wasn´t lazy along the way. I have some questions regarding my progression and cm-measurements which confuse me a little bit, maybe you can help me out. A little bit of history first, so let´s get started:
My starting point last year in April was (according to optometrist):
R -1,75 with -1.25 cyl. 105°
L -2.00 with - 1.5 cyl. 90°
which seemed to be too strong for me.
My own measurement showed on average:
R -1,75 with -0.5 to -0.75 cyl. 105°
L -2.00 with 0.75 to - 1 cyl. 90°
It took some months to learn AF, played around with glasses with reduced cylinder, without cylinder, reduced spherical correction, but eventually towards the end of summer I found it by not using glasses at all, which seemed to give me some stimulus. It really was a huge thing, mainly focusing on the sensation of relaxing the eyes and letting them work. And then I noticed some improvements, here you can see the general progression:
Right now, my measurements on average show:
R -1,25 with -1 cyl. 105°
L -1.5 with - 1 to -1.25 cyl. 90°
According to the graphs, along with the spherical reduction the cylinder increased. In cm, the cylinder stayed more or less on the same values both right and left, only spherical improved.
Subjectively I notice that my vision became mostly double vision, often I can read even small writing on the tv (covered by multiple images). Looking outside, e.g. trees branches, license plates etc. kind of pop into sharp focus, but appear mostly doubled. All that without glasses, this seems to give me the most stimulus, with glasses I cannot manage to achieve that.
Now some things I noticed playing around with cylinder correction and measurements:
Putting on glasses with cylinder correction, which make me see the lines on the astigmatism chart all perfectly black, I tried holding a +0.5 lense in front of my eyes. In theory I thought, all lines should become equally blurred, like having no cylinder should be. Instead, the blur showed on the exact same axis like with glasses without any cilyinder correction, letting me see only the horizontal lines black.
Doing measurements with the same plus lense in front of my eyes, it gave me following results:
R -1,75 with -0.5 cyl. 105°
L -2 with - 0.75 cyl. 90°
Again, the spherical cm-measurements changed according to theory, the cylinder values stayed the same
SO enough reporting, now to my questions:
Do these things make general sense, or is there something off? Could it be the astigmatism (which in ratio is quite high anyway) is some kind of double vision/mental thing, and not like a biological/optical issue? Or do I have a logical error somewhere?
I know Jake mentioned that during the process of improvement, double vision acually may be mistaken for astigmatism, did my astigmatism actually get worse, or did the double vision increase accidentally on the same axis as my astigmatism?
I wonder what would be the correct approach, since I dont´t want the astigmatism to get any higher, but wearing glasses just doesn´t give me the stimulus for AF.
I also notice that if the image pops into focus, and I look at the astigmatism wheel haning in my living room, the sharp lines always switch in axis, like from 90° to 0°, next time may be 45° etc…
I hope you guys can set me straight.
All the best
