The new medicine takes effect in about 15 minutes, with one drop on each eye providing sharper vision for six to 10 hours, according to the company…. Vuity is the first FDA-approved eye drop to treat age-related blurry near vision, also known as presbyopia. The prescription drug utilizes the eye’s natural ability to reduce its pupil size, said Dr. George Waring, the principal investigator for the trial.

“Reducing the pupil size expands the depth of field or the depth of focus, and that allows you to focus at different ranges naturally,” he said.

A 30-day supply of the drug will cost about $80 and works best in people 40 to 55 years old, a Vuity spokesperson said. Side effects detected in the three-month trial included headaches and red eyes, the company said.
