Astigmatism is a bitch in the way that you cannot compensate it by moving closer or further relative to the computer screen. You need to use your prescription glasses or you will face eyestrain, period. I have heavy myopia, astigmatism and went through cataracts procedure, so my eyesight is not really eagle like. What works for me is using light background themes (night/dark schemes do not really work) and increasing the terminal/editor font size and decreasing the screen resolution (I have my 4k monitor running at 1920x1080, so there you go). Also, do not code at night without indirect lighting, your pupils will be thankful. But the most important thing is: do not neglect your eyes. If you were prescripted glasses, use them, and visit the doctor every year.
