I'm 20 years old female. My left eye power has sph - 0.50,cyl is - 0.50 and axis is 180 and right eye power has only sph that is - 0.75. And the vision is 6/6 for both eyes. But I have no eye pain, no strain, only blurry vision when the distance of the thing is more. And the axis 180 meaning? Is it bad? Is astigmatism very bad? Is it harmful? Is my eye power is very poor? Is my astigmatism is severe? What should I do? Do I need to wear glasses all the time? Or will it affect my eyes more like will my power increase or decrease after some months? I want to decrease my eye power, to make it constant what can I do?
