Semi-rimless frames have become very popular these days among people in all aging groups, due to the reason that they can make people look trustworthy and intellectually mature. However, not all people are suitable for semi rimless glasses. If you are planning to buy semi-rimless glasses recently, it is worth spending a bit time reading through the following article.
Generally speaking, there are three types of people who are not recommended to choose the half rimless eyeglasses frames: 1. People have an imbalanced prescription 2. People have a low prescription with a small PD (Pupillay Distance) value 3. People who want to choose a polarized sunglasses lenses.
As we know, the stronger your prescription is, the thicker the lenses center will be for near-sighted prescription. In contrast, the thicker the edge of the lens will be for far sighted prescription. If you have an imbalanced prescription, the thickness between the prescription lenses will be different. To get a better appearance, those people are recommended to select a full rim glasses frame. The bottom portion of a half-rimless frame is held by a filament and it requires the technicians to cut a groove. If your prescription is lower than negative 3.00, the edge portion will be too thin, and it will be insufficient for the lab workers to put a slot on and hold the lens properly with the filament. In addition, if you would like to polarized sunglasses, you should avoid choosing the half-rimless frame, otherwise, the polarized coating on your polarized sunglass lenses will easily be peeled off.
