Eye drops could replace glasses or surgery for longsightedness, study says

Research shows most patients can read extra lines on eye test charts after twice-daily treatment

Hundreds of millions of people worldwide have presbyopia, which is when the eyes find it difficult to focus on objects and text up close. Glasses or surgery can usually resolve the problem but many find wearing spectacles inconvenient and having an operation is not an option for everyone.
