| Presbyopia Presbyopia is a natural, inescapable and irreversible visual deficiency. When people are in their forties, the crystalline lens's accommodation capability becomes inadequate for a clear and comfortable near vision. Presbyopes tend to stretch out their arms to move back the texts they read. Presbyopia can be combined with other visual disorders (myopia or hyperopia, astigmatism). Without ophthalmic lenses, near vision becomes difficult. |
