Progressive muti-focal reading glasses become increasingly popular. But it requires certain adaptation during the wearing process. We should find a scientific way to see the process of adaptation. If you begin to wear bifocal or progressive eyeglasses frames, you need to learn how to see things in varied distances.

• To look at the objects in the distance: you should raise your head and look straight ahead through the upper area of the lens ( areas for the distance) to see the objects.
• To look at the objects nearby: your head should keep a 45°angle with the level, and turn the eyeballs down through the down part of the lens (areas for near things).
• See things at the middle distance from the middle part of the lenses.
• The nearer the objects locate, the lower of the lenses your eyes should focus on and vice versa.

For green hand in using multifocal glasses frames, it is common to encounter with following uncomfortable feelings.

• You will feel a little faint, and when you are dong some sports and climbing up stairs, are the first thing you have to be care of. so you need to be careful to climb the stairs.
• You may falsely assume that there is something wrong with the objects you see. You may make an inaccurate decision on the judgment of distance.
• When looking at close quarters, the eyes are downward with mild discomfort.
• It is hard for you to see things clearly if you look things through the edge of the lenses.

Therefore, new wearers must move heads more but run eyeballs less when seeing something. and use the distant, nearby and mid area to see the objects.
