Prescription change to remove astigmatism?

I had an eye exam a year and a half ago, my contacts were
left -3.25 right -4.00, glasses were left -3.25 right -4.00 -0.25 x005. My glasses always felt too weak, I think especially in the right eye.
This year I got an exam a month ago, and my prescription was changed to left -3.25 right -4.25 and glasses left -3.25 and right to -4.25.

When I asked my doctor if my astigmatism disappeared, he said no, but that I didn't need to specify it as it is very minor astigmatism and I could just get a regular lens.

This seems really odd to me, does it sound right to anyone?

Thanks!!

He said that my astigmatism still is the same -.25, however because I found the right eye weak in the old glasses, he just upped it to solid -4.25, instead of -4.25 -.25 x005.

Since your astigmatism was literally so low before it is likely in the new eye exam it was under 0.25 and they only make lenses in 0.25 power increments so astigmatism under that will not be corrected. 0.25 is the lowest power increment that is made in optical lenses. So yes it is possible in your eye exam it read your astigmatism is lower then a quarter diopter (0.25) and anything under that there is really no way to correct it.
As for contact lenses they do not make any toric lenses for astigmatism with a "cyl" or "cylinder" any lower then 0.75 so for contacts even if you have a 0.25 or even 0.50 cyl it will go uncorrected since they do not make them any lower.
So yes that does sound right to me !

I think with glasses you do need a correction for astigmatism even if its just -1/4, with contact lenses it's different.
