The discount prescription glasses are a decoration, but more importantly, they are used to correct vision.

First of all, we need to know that lenses are all optical center points, and the eye can only see objects comfortably, clearly, and not easily fatigued through the central area. This is also the significance of the pupillary distance that we need when fitting lenses.

Myopia discount prescription glasses lenses can be understood as a circle composed of many prisms with their bottom facing outward, and the optical center point does not produce a prism effect. But when viewed from an area far away from the center point, a prism effect occurs.

By looking through a bottom-facing prism, the object you see will move towards the top of the prism (downwards).

If you don't look through an area far from the center point, it can cause deformation, blurriness, shaking, and easy visual fatigue when viewing objects. Individual differences are significant. Some people have good tolerance and no sensation, while others may feel nauseous and need a long time to adapt. It's easy to increase the degree, but once it goes up, it can't go down!

Once you have knowledge, you will know whether you should wear glasses with large frames. It's not too late to know now! So can't we consider large circular frames?

That's not true either. If you wear the glasses frame on your face, adjusting the nose support to choose the appropriate discount prescription glasses frame for your eyes and considering the position of your glasses and the height of your pupils to match them can greatly avoid being unscientific.
