How to choose the best frame for different prescriptions?
In fact, different prescriptions mean that you have to choose different frames. Otherwise, you will be uncomfortable wearing them. The wrong frame may even affect your vision.
If you have mild prescription (less than -3.00 diopters), you can choose any kind of frame you like. Of course, the larger the frame, the heavier and thicker the lenses.
If you have moderate prescription (-3.00 to -6.00 diopters), you can choose any type of frame that is not oversized. 50-54mm size of frames are the best.
The best frames for a strong prescription (more than -6.00 diopters) should be small and round or oval. You should avoid large frames.
If you have hyperopia/farsightedness, do not choose a large frame because the diameter of a hyperopia lens is very small, generally no more than 60mm. when the lens is processed, the center point should be shifted according to your own pupillary distance. If the frame is too large, the PD displacement may be inaccurate. This is also applicable for all the other wearers. If your pupillary distance is short, don’t choose oversized frames.
