I understand. I'm 77 and have been fighting glaucoma for over 30 years. I am a candidate for xen-gen surgery when max eye drops no longer hold pressure down. I too have low vision now with only central vision in right eye, and lots of problems with glare. I also have high contrast white on black computer setting. I have a goose neck lamp by my computer to shine bright light on documents I have to read, and I always carry pen flashlight with me all the time.
I hope your surgery goes well!
