very interesting ... I've had tremendous frustration from optometrists insisting that I have a fixed prescription, but invariably whatever they prescribe me ends up wrong. In the end I ignored my optometrist, found a way to order online and ordered every single prescription for contacts from -5.5 to -6.5 with a couple of options for other parameters and literally just tried them all. What I found was that my "correct" prescription really, truly varies, ... even over a period of just days. So I ended up just switching between different contacts as needed. But one effect I observed is that a great sequence was to wear slightly under-strength lenses for a week or so and then switch up a level. This seems to do what you suggest ... my eyes then slot into the correct strength with improved comfort and vision and often stabilise there. Every now and then, everything tips over (often if I get a really bad sleep for some reason) and then I go back to the "slightly under strength" option to try and reset. All of this I've figured out purely empiracally because I've been so unhappy with the options that multiple optometrists provided me .... so its nice to hear someone say something vaguely similar to what I experience!

You might want to test to see if you have an astigmatism, in most cases you have it from birth, but I somehow developed it. Take a look at this chart: https://static2.feelgoodcontacts.net/images/astigmatism-degree.jpg https://static2.feelgoodcontacts.net/images/astigmatism-degr... Basically all the lines should look equally sharp when your vision is corrected. In my case - if I don't wear glasses and move close enough to see it clearly - the horizontal lines have a shadow going upwards, where as the vertical lines are sharp. The shadow is strongest on the 0 degree and 180 degree lines, meaning I have an astigmatism at one of those. This doesn't tell you what the correction should be, but it tells you if you have it.
