Growing number and Presbyopia

In presbyopia, the most unpleasant experience is the switch from a reality of perfect near vision to an occasional need, and later, a complete dependency on reading glasses. However, there is another uncomfortable phenomenon that has to do with presbyopia – the growing “number” or “prescription” of the reading glasses , that is the amount of optical correction needed for restoring perfect near vision. Due to a continuous change on the anatomy of the eye in presbyopia, its ability to focus on near objects gradually degrades, resulting in a continuously increasing power of the required optical correction. The outcome of this need is the need for purchasing new pairs of reading glasses every once in a while, until the lens reaches its final state, requiring full optical correction. This process may last a few years! Throughout this period, people with presbyopia typically purchase several pairs of reading glasses for every prescription, in order to have them at hand both at home, in the office and in the handbag. Consequently, a lot of money is spent on reading glasses that become useless as presbyopia progresses. However, such a significant distress caused by the need to maintain the correct pair of reading glasses can be avoided by brain training starting with initial symptoms of presbyopia.
