So, I’m probably not the best case to answer the question, but having gone from a spherical equivalent of -4.75/-4.25 down to -2.25 (and dropping, yessss), I have noticed a lot.
Even when things are “blurry,” they have a clarity they did not. It was not too many months ago I was looking about without lenses and wondering why everything looked so awful, now I am on the cusp of seeing very well.
I noticed over the last few years with a high use of blue blocking tint in my reading glasses that when I wore the clear lenses, green tints seemed much more obvious and distinct. I haven’t had blue tint since I started with EM and Zenni last summer/fall, but I still experience the vibrancy of the colors. I do note that when I look at the full moon, and some outdoor lamps, that the Zenni lenses have a green reflection artifact. Just the tiniest bit. (I’m currently in -1.75 sphere, -1.00 cylinder, bilaterally).
It’s easier for me to pick up on perspective orientation now.
I mentioned in a previous post that night vision seems to be improving. I often end my days by standing at the window or on my balcony and looking out; I believe I’m seeing into the dark spaces much more clearly, and I can see the graduations as light falls on objects further from its source much better. That was one thing I noticed when I was at my peak worst vision: when I was a kid with perfect vision, I could see light from oncoming vehicles before the vehicle was in sight. I lost that ability completely at my peak worst vision; it seems to be coming back.
Our apartment complexes are designed with a rock garden in the center courtyard of each building. I can see two of these across the parking lot from my balcony. A few weeks ago, I noticed that I can now tell, without glasses, the difference between the concrete paving and the gravel/stones, although they are almost the same color.
It’s always a shock when you realize you can see something now that you couldn’t see before under whatever conditions–no glasses, diffs, or even norms. I noticed the subway tile in my kitchen a few months ago. I can now pretty much read the clock on my Sirius home radio now without glasses, when it’s off (the font is much smaller when it’s on).
More to come.
Best of luck! Keep up those good habits.
