Dominic I've never tried to use cyclopegic eye drops, as it never came to my mind.
I have no prior experience with correcting my astigmatism, but here is a full story of this single correction attempt.
Astigmatism found: somewhere in 2018-2013, don't remember exactly.
Days when my eyes were tired from 15 hours screen time per day, since 2013: zero
Do I feel my astigmatism in daily life: no. I feel it only when I look with one right eye
How I do perceive my vision on a daily basis: as 1 (perfect). Sometimes very slightly below
When all this unexplainable phone eyestrain started this autumn, I went to optics to correct my astigmatism and see how it goes. I can't find prescription and measurements from October, but here are measurements from November (subjectively there was something wrong with my eyesight at the moment):
Left eye vision test: 1
Right eye vision test: 0,4
Left eye: sph +0,25 cyl - 0,75 ax 122
Right eye: sph +0,25 cyl - 1,75 ax 84
Correction attempt in October: one lens solely for the right eye (worse one). Left eye rejected any correction
Wearing lens all the day: moderately ok, no problems with eyesight, no red eyes, some spatial disorientation due to image distortion by lens.
Wearing lens later with the phone:
- Spasm/pressure was almost not present on the right eye
- Right eye tried to focus maybe 50 times in a row on the phone, just like camera. It was so very noticeable. It eventually failed to find a focus, got tired, unfocused and rejected any further attempts to focus.
- Results were the same when I looked with one eye or with both eyes
- Right eye turned absolutely red in 20 minutes. I could attribute that to lens but it was ok all day and started when I took the phone. And also it happened before with no lens.
Correction attempt was made prior to finding phone influence on my binocular vision. When I tried to correct BV at the very beginning with stereograms, I got an unexplainable result: not only my spasm was gone but also my right eye became almost as good as the left one for a few hours.
My phone made things much worse since October, and I can't check that magical effect further.
Maybe when all this madness stops, and my eyes are fine, I will try to do exercises and see what will happen to my eyesight.
