For the presbyopia people who have myopia, astigmatism or hyperopia, the most traditional solution is to prepare two pairs of glasses with different degrees to meet the vision needs of far and near use respectively. This scheme has simple principle, low adaptation threshold, and is economical and practical. It is suitable for most people who have requirements for far and near vision.

If daily work and life need to frequently switch between near and far use of eyes, pursue convenience, accept a certain adaptation cycle and a higher budget, a pair of progressive multifocal glasses will have a better experience, and can meet all the needs of looking far, middle and near at the same time.

1、 Single light reading glasses:

Through a fixed positive degree lens, the light entering the eye is directly focused in advance to compensate for the lack of eye adjustment force, so that the imaging of near objects just falls on the retina, helping the eye to focus on close-range targets optically and solving the problem of blurred vision.

2、 Double light reading glasses:

The lens is divided into upper and lower areas. The upper part is the far use degree, and the lower part increases the positive degree for close viewing. At the same time, it can meet the correction needs of both far and near distances, and solve the problem of frequent replacement of glasses for distance viewing.

3、 Progressive multifocal reading glasses:

On the same lens, it realizes the continuous natural change of the distance degrees of far, medium and near, and the gradual transition from the distance to the near degree, which can not only correct the old flowers, but also meet the visual needs of different distances. It can obtain clear imaging throughout the whole process, and solves the defect that the traditional presbyopia glasses can only see the old flowers in the near and double light.
