My Mom had non treatable macular, had lost sight in the left eye and it had moved into the right eye along with glaucoma. Our Ophthalmologist said to take 40mg of straight Lutein which I purchased thru Puritans Pride. She took it for the summer, it reversed the macular in the right eye, no more glaucoma and she got sight back in her left eye. She passed away a few years later, I started taking the 40mg Lutein once a day and my eyes got so better that I went from the glasses I had in 2020 back to 1995. I just got my eyes reexamined, and she was shocked at how my sight had improved.
