Since my previous outdoor time experiment gathered quite some interest, I’m going to record a similar episode for the dreaded dark season.
I’ve been trying to provide hard evidence for the Reduced Lens Method for over a year now, measuring my eyes and recording the results. Last year, I took the dark days here in the north too lightly. The bill came in the form of worsening myopia and significant elongation of both eyes, thwarting my first attempt of producing evidence just as I got my own IOL Master, which allows me to measure my eyes’ length regularly.
You can see how things unfolded since then in my all-time chart:
The top chart is refraction; note that up is better there. The bottom graphs show how the length of my eyes changed, with slow but almost continuous shortening since spring. By looking at both kinds of graphs, you can see how shorter eyes correspond to better distance vision and vice-versa.
All this means: now is a decisive time! Will my eyes worsen again, turning this into a Sisyphean back-and-forth? Or can I keep my shortened eyes until spring? Or, if I dare to wish, might it even be possible to keep improving in winter?
Overcoming this obstacle would not only give me the prospect of better vision every year, but also leave a permanent record for all the naysayers, showing beyond reasonable doubt that eyes can shorten over the long run! So, can they really?
The main changes I’m pushing, compared to last winter, are:
- Trying to catch more outdoor daylight around noon.
- Computer glasses reduced twice (0.5 dpt less spherical; now using -1.75 on PC at ~90cm).
- Distance glasses roughly reduced twice (maybe a bit less due to details on glasses usage).
- Much stronger indoor lighting has been installed.
Edit: outdated 2019-12-13:
Trying to sleep earlier than last winter, to avoid missing daylight by sleeping in.
- Edit: added 2019-12-13: Trying to shift computer use to earlier times in the day, to avoid excessive eyestrain after sunset.
I put this into the 20/20 Gains Updates category, since preliminary results already indicate a small year-over-year improvement, especially on my left eye. But so far, this is still based on thin data and not enough time. Over the next three months, the outcome will become a lot clearer.
At the time of this writing (2019-11-29) the darkest day of the year on average here, Christmas Eve, is now 25 days away. The period in which the elongation most likely happened last year has already started for this year, and ends in 21 days, three weeks from now. My current AL EMAs are: 25.723 mm left and 25.796 mm right – all-time record levels, as you can see in the charts.
If we turn this into a contest between mainstream optometry’s “nothing can be done” and us trickster kittehs – which of course I’m doing – the data at this early point seems slightly in favor of improvement, with both eyes’ axial lengths’ moving averages below the first few samples I have from roughly one year ago. But the real decision is coming up now, with the solstice and deepest winter days ahead.
So, onward through the long nights! There will be regular updates as usual, and year-over-year comparisons of axial length will appear, with increasing precision. Feel free to comment with opinions or your experience with the dark days!
