Did you even read my reply? The rx gets transposed to minus cyl and both the old and new rx are almost identical. I don't know what your uncle told you but a 10 degree difference on the axis is not the end of the world. Sure your vision is a bit distorted but the axis rotation is only 10 degrees off between 10 and 180. In fact, if your glasses rx had an axis of 5 or 6 or 4 then that's probably why the dr put you in a 10 because that kind of axis is between 180 and 10. There's no point of fadeaway getting a "2nd opinion" unless his old rx is giving him major issues because I am willing to bet the dr autorefracted him before he used the foropter in him
A 10 degree change in axis with a cylinder of 2.00 D is a HUGE difference. The standards for cylinder axis are: 0.25 D: +/- 14 degrees 0.50 D: +/- 7 degrees 0.75 D: +/- 5 degrees 1.00 - 1.50 D: +/- 3 degrees > 1.50 D: +/- 2 degrees So True Beaner had to be prescribed anything between 178 - 002 degrees to have no noticeable difference in visual acuity. However, since he said he had no problems in acuity, rather having headaches, I think his contact lenses did not fit him properly. Contact lenses with astigmatism are quite finicky and rotate around the eye even if the base curve and size are as accurate as possible. The bad fit probably caused temporary blurriness which clears up, but the strain of having to adjust to blurry vision for a bit would give headaches.
lol wow you must have a lot of knowledge about this b.c I didn't even add that the contacts didn't fit me properly and would always rotate and you already knew that. I had acuvue Oyasis, and now I have airoptix. Also, would you consider a change in cylindrical number of .5 big? I am 2.25 and 1.5 in each eye, my cyl number really increased .
I'm an optometry student. I wouldn't say a change in 0.50 D of cylinder power is that big of a change. Depending on who checks your eyes, your sphere and cylinder may go back and forth in a tug-of-war, but they will generally add up to the same power in one direction. My optometrist prescribed me 0.25 D of cylinder, yet when we practice at school, I can go up to 1.00 D of cylinder as long as 0.75 D is taken away from my sphere. I still get good 20/20 or 20/15 vision from it. Remember, your prescription is based on your subjective results. There are objective ways to measure the power of your eyes, but that doesn't matter if it doesn't give you the vision that you see best with.
