Dear Nikola,

If I understand correctly, you have discharge from both eyes,
and see colored rings in both eyes. Elevated pressure is not
associated with discharge. Therefore, if the colored rings
are to be attributed to high pressure, one must, in violation
of Occam's razor, hypothesize the simultaneous onset of three 
separate illnesses. The simultaneous onset of high pressure
in both eyes, though not impossible is also unlikely and 
in violation of Occam's rule. Therefore it seems to me much
more probable that pus and/or mucus from commonly occuring
bilateral conjunctivitis explains both the blurring and the 
colored rings, than that you have experienced the simultaneous 
onset of three independently occurring disorders: viz, bilateral
conjunctivitis, acute glaucoma right eye, and acute glaucoma 
left eye.

I am reminded however of the teaching of the Hippocratics,
that the physician must observe the patient, and that the physician
who theorizes rather than observes, will do his patient great harm. 
I cannot advise, and YOU must decide, whether or not to consult
an ophthalmologist in India.

The changes in air pressure attendant on altitude changes have
no known effect on the eyes.
