Axis and meaning

The axis in my R eye is 10 and L eye is 167. This is basically the inverse of each other. Does this mean anything or can this help me out anyway?

When the axis is a different in each eye it might help you see better with both eyes than you could with either eye all by itself. Some people think very small amounts of astigmatism might be normal or helpful.

If you’re trying to get rid of astigmatism you should look at your work environment and see if anything is set up off-center (do you have a screen on one side of your desk, is the light coming through a window on one side only, etc.)

Interesting. Sometimes I do have my laptop off center.

Muscians in an orchestra get astigmatism in predictable ways because their sheet music is off to one side or the other (and their head is tilted depending on which instrument they play.)

It does look like inverse at first sight but actually this is misleading as the difference is so small that they are both within the horizontal line. Look at the below and you will see that 10 and 167 are marked at both ends of the horizontal line, so they are on the same line, not mirrored. (They call it mirrored typically if the axis is between 120 and 150 in one eye and 30 and 60 in the other eye)

If it was newly added to your prescription and was below -0.75D cyl before starting EM it would be quite easy to fix. But even with your long term prescribed -1.25D it is not impossible to improve. Just takes a bit longer as you are most probably used to the distortion of the cyl added to your prescription.

When astigmatism appears around 180 degree it may be an indicator that while you move your eyes vertically up and down OK, your eyes are not moving horizontally left and right on the full range of motion. See the second pic below for the “preference for vertical scanning” (regardless of headtilt)
A.R. astigmatism means axis around the horizontal line.


There are 2 options why the vertical scan may be dominant:

  1. people use one axis less than normal (e.g. working on one monitor, focusing in for work and not looking left and right, can happen with mid or high myopia when the peripheral vision is lost in glasses already - so this is the underuse of the horizontal movements)
  2. people use one axis more than the other parts of the eye (e.g. musicians like trumpet or trombone players looking ahead at the instrument and then looking ahead at the sheet note, too. Or customer service people sitting in boxes with customer standing opposite and monitor in between, so overusing vertical movements as a natural consequence of the workstation set-up, or student looking up at the monitor and down at the notebook or smartphone, train drivers, etc)

Reducing cyl is work for the brain as the cyl around 180 corrects the image stronger horizontally than vertically. (Distorts the normal image to an oval) When you take away from the cyl, the brain has to equalise within the eye, the brain has to correct the input of oval and correct it to a circle.

What I can suggest on top of EM is

  1. holding your head still and moving your eyes left and right every time you can remember to do it during the day. Not straining, just trying to move the eyes along the full natural range of motion. You may even experience a bit of discomfort if you are very much not used to this. You may even notice that your head automatically moves with your eyes.
  2. The other thing is to keep your thumb up in front of you and turn your head left and right while keeping your eyes on the thumb.
  3. Finally you can hold up both your thumbs in front of you, and move them apart to the sides while keeping your eyes looking forward but still trying to keep note of the thumbs moving in the peripheral vision.

No reps and sets. No strains or muscle aches. Just gentle movement along the natural but full range of motion whenever you remember during the day. You should see changes after a week.

You may find these pics useful, too. Especially for checking the parallel lines before and after moving your eyes left and right a bit.
