Roseanne Barr revealed she is losing her vision in a candid interview with the Daily Beast.

She made the revelation while discussing her love of marijuana. The 62-year-old comedian said she has macular degeneration and glaucoma, and is dealing with pressure in her eyes. Weed, she said, is ” a good medicine.”

Barr admitted doctors cannot give her a time frame for when she will ultimately go blind.

“No, they can’t. My vision is closing in now,” Barr told the Daily Beast. “It’s something weird. But there are other weird things. That one’s harsh, ’cause I read a lot, and then I thought, ‘Well, I guess I could hire somebody to read for me and read to me.’ But I like words and I like looking. You do what you have to do. I just try and enjoy vision as much as possible — y’know, living it up. My dad had it, too.”

She tweeted about her symptoms Monday, clarifying that she is not blind yet.

Macular degeneration leads to haziness of the vision and can result in a blind spot in the center of the vision field, according to Mayo Clinic. Glaucoma is a group of eye conditions that cause nerve damage and can lead to vision loss.
