Vision recovery training

Line-up of glasses and contacts at the same time that the rich have been explained, evolved over the years and training leading to the recovery of vision presbyopia correction, various methods have been devised.
There are a variety of modern ranging from those that match the old, I will be able to choose the method that suits his training.
Here, we will introduce a variety of vision recovery training.

The first is the training to use (pinhole glasses) glasses that has a hole.
Also referred to as spectacle lens rather than the lens portion, like a black plate is fitted, has several small holes drilled into it.
Use this hole, is the phenomenon in order to recover pinhole vision.

A pinhole phenomenon is a phenomenon that seems fine enough, you need to align the focus is no longer impossible if the light, so that the vision was getting better.
Lens to aggregate the light came in, when you see things eye, it is focused on the retina at the back, but things are still visible clearly.
However, earlier than the retina or was, and which will cause further focus in the back, become myopia or hyperopia.
Light entering the eye is thin and enters as one muscle, the lens is no longer necessary to aggregate the light will be focused at any position.

Is due to ciliary muscle of the eye and will be in tension by looking at something for a long time, eyestrain leading to vision loss, the let me stiff.
Because there is no need to adjust the focus to see things and pinhole glasses, you will be able to rest the muscles of the eye.
Also, if you can see the near and far with this pinhole glasses, but also to train the ciliary body training, leading to the recovery of vision and presbyopia correction, too.
