A young eye lens is very elastic and is therefore able to change shape easily. This allows us to focus the eyes on both near and distant objects, and enables us to see clearly. This ability is also called [...] increasingly further away - the near point is the closest point at which an object can be brought into focus by the eye. How can presbyopia be treated? As the accommodation ability of the eye is different for
