A new drug that could help more than 128 million Americans read without needing glasses has been submitted to the Food and Drug Administration for approval.

The investigational eye drop – called AGN-190584 – is expected to be approved by the end of this year, according to a statement released last week by Allergan Eye Car, an AbbVie company.

The eye drops are a pilocarpine solution meant to treat the symptoms of presbyopia, which is an age-related condition that causes gradual loss of the eyes’ ability to focus on nearby objects, according to the Mayo Clinic.
