Actually, those eye drops are to treat presbyopia which uses a different mechanism. Presbyopia typically affects older people and presents as long-sightedness (not short-sight like I described earlier). Presbyopia causes the lens in the eye to lose its elasticity and causes the eye to focus light behind the retina. Curiously, a similar effect (longsight) can be caused by the eyeball being too short (hypermetropia). That said the eye drops sound like pretty cool treatment.
