Sayuri, a "Sanketsu-girl," who is set to sing Lycoris Recoil's final theme song "Hana no To" this season, has been diagnosed with glaucoma, which the CDC, the United States' national public health agency, describes as "a group of conditions that can result in vision loss and even blindness."
On September 17, the 26-year-old singer tweeted that her severe nearsightedness caused her to wear contact lenses, which resulted in keratitis, inflammation, or cornea infection. The condition improved, but after a thorough examination at an ophthalmology clinic, she discovered that she has glaucoma.
"[Glaucoma] was discovered early, so putting in eye drops correctly leaves me little chance of going blind," but she admits it does bother her a little because she is still in her 20s.
The CDC cautions that "anyone can get glaucoma, but certain groups are at increased danger," including African Americans over the age of 40, all people over the age of 60, people with a family history of glaucoma, and diabetics.
Lycoris Recoil's non-credit closing sequence with her song "Hana no To" has attracted more than 2 million views as of the time of writing: Check out the 1-minute and 30-second video on Aniplex's YouTube channel below:
