It is impossible to comment on your eye heath as you have not supplied any medical information concerning your eye, your eye pressure, your optic nerve or anything else.
All I can say from what you have posted is that I am concerned about the quality of your glaucoma management, especially since glaucoma causes irreversible total, lights-out blindness
if not treated correctly.
In that light I feel you have a serious ophthalmic condition. This condition can cause blindness. You do not seem to be getting appropriate care, although lumigan and timolol are the correct drops to use. I do not know what the generic one is....
I realize that this was not the answer you were hoping to hear but it would be unfair to you and unprofessional of me were I provide you with anything less than truthful and honest information.
Surely, you prefer that I tell the truth rather than what you wish to hear. Because it reflects very poorly on me unless you press one of the top three feedback choices, keep this in mind when rating my answer and please do not punish me for being honest. I understand that this may not be easy to hear, and I empathize.
