Over the past centuries, eyeglasses fitting over people’s faces are the dominant form of eyewear. And according to this common wearing approach, these devices are sometimes called face eyeglasses. Nearly all forms of eyewear products including regular prescription eyeglasses, sunglasses and safety goggles are put over the eyes. These devices are used in order to get vision correction or eye protection against harmful rays or dangerous particles. Both of these two purposes are associated with the eyes. And in some cases these products are called optics glasses. It is absolutely true that the eye is the exact target that requires visual aid or protection. But it is incorrect to suppose that all related devices should be placed in front of the eyes if they will function properly. Face glasses represent only one form of optical devices for the eyes’ behalf. Among presbyopic patients, there are other forms of magnifying devices.
It is widely known that regular reading glasses are used by presbyopic patients to read materials that are close-up. They eliminate the necessity to hold books and newspapers intentionally in the distance. Thanks to lens technological improvement, now there are widely available bifocal reading glasses, trifocal reading glasses and even progressive glasses, all of which can deal with presbyopia. Certainly, these all belong to face eyeglasses. What are beyond this category include some hand-held magnifiers and special magnifying platforms. These devices will not stay on the user’s face. Instead, they will be held or just stand on the desk. Compared with regular reading glasses including single-vision and multifocal ones, these devices are more professional in magnifying reading materials. Thus they are also widely used by folks in their 40s, 50s and over.
Another point related with face eyeglasses is that there are some tips while selecting an appropriate pair. And these tips are associated with the wearer’s face. Facial shape and facial size are the most decisive. Each customer has personal features in these two aspects. For instance, some people have a round face and some others’ faces are rectangle. The selected frame should have a shape contrasting with the wearer’s face shape. While considering frame size, it is generally determined by the wearer’s face size that they should be in scale.
