How to choose a progressive lens

Even though the use of glasses for presbyopia correction, now is the time when asked appearance.
The way to start out at a young age if symptoms of presbyopia, and want to choose the design of smart glasses, progressive lenses is not too bad to look mainstream.
Whether you are thinking of buying a bifocals now, it would be more likely to choose here.
Here, I will look at the choice of progressive lenses often used to presbyopia correction.

With glasses that do not fit the frequency, there is not only uncomfortable to the eyes, you would feel even worse.
What is important therefore is the "power addition" of the lens.
The difference in the frequency of each of the part to see the near or distant, the frequency and subscribers, this difference has been involved in the appearance and breadth of vision.
Both correspond to perspective, those corresponding to both in the near those corresponding to the short distance, the progressive power addition of the lens is divided into four large but reduces the eye strain.

The bifocals, the more distant frequency.
Two intermediate and proximal are well-balanced distribution.
Near many amphibious Middle, have been reduced in the distance.
In the near future for both, the frequency of the near is almost as its name suggests.
Reducing eye strain, most is configured in degrees distant.

Recommended for those who want to spend in the glasses always, bifocals, you can also use this among beginners.
For both near, and are suitable for those who want to have separate glasses, bifocals is for those who do not fit in with bifocals.
To live does not mean wearing glasses all the time, in the near future for both is a lens that matches the person you would like to use a pin point.
Reduce eye strain is very similar to bifocals, it is suitable for those who work to see what is close to a long period of time.

I do not know but it looks like this is not suitable for general orientation, those glasses that will not actually try to use.
Therefore, to try all kinds of it would be a good idea.
