A pharmaceutical company called Allergan has developed eye drops that can help to treat presbyopia – close-up blurred vision. This often starts when people get into their 40s. It affects over a billion people around the globe. The eye drops are called Vuity. Allergan said Vuity is "the first and only FDA-approved eye drop to treat age-related Blurry Near Vision (presbyopia) in adults". It added they "may help patients…see up close".
Presbyopia sufferers make the text on phone and computer screens bigger. The eye drops could help people see text more clearly. Clinical studies showed that people who used Vuity every day did better on eye chart tests. They saw three or more lines on a near-vision eye chart. The eye drops reduce the eye's pupil size. This helps people to focus on text and objects that are near them. A user who tested the drops said they helped him to read smaller letters.
