Problem with eyes in zazen
I was wondering if anyone else has been experiencing problems with their eyes in Zazen. When I sit in Zazen, my eyes tend to move involuntarily, they hurt, I get tears, the focus keeps shifting even though I am trying to keep them unfocused. It ruins my sitting. I use eye drops, I have tried everything, nothing helps, I end up just getting angry. I am relatively new to zazen, but I have practiced the shamata meditation before in a different tradition, with eyes closed and it's been working much better. My eyes have always been very sensitive to light, I work with computers, and being of European stock, my eyes are obviously anatomically different from the Chinese/Japanese type. Asked a few Zen teachers, the answers so far provided nothing of practical value.
Can anyone please offer some advice, or it this God telling me to switch to another school of Buddhism?
Gassho,
