The Food and Drug Administration authorized eye drops that may possibly replace reading glasses for millions of people in October, and they entered the market this week.
"It's definitely a life changer," trial participant Toni Wright told CBS.
"I would not need my readers as much, especially on the computer, where I would always need to have them on."
The drops, known as pilocarpine, and sold by pharma outlet Allergan under the name "Vuity," might help the 128 million people in the United States who are nearsighted.
One drop in each eye, according to the business, may enhance closeup eyesight for six to ten hours, according to CBS News.
