Today, eyeglasses come in a couple of different forms, like myopia glasses, hyperopia glasses, reading glasses, bifocals, trifocals, tinted eyeglasses and bifocal safety glasses and so forth. These different names actually reflect specific functions of these products. In this article, we create a universal name for all these prescription glasses: nose eyeglasses. Well, this name only says that these glasses are worn over the user’s nose. All of us know that prescription eyeglasses are designed to help patients with poor eyesight “regain” clear vision in different distances. For patients whose vision problems reaching a certain degree of severity, it is necessary to make a pair of prescription glasses stay on the nose frequently or even day long on a regular basis. Staying on the nose on a daily basis, these glasses are thus sometimes called nose glasses. Of course, people who use prescription glasses on a part-time basis also wear them on the nose. A same situation can be found in sunglasses and safety glasses fields.
It is necessary to make modern eyewear users know that those commonly seen products in modern eyewear market are not the single form in the long eyewear history. Nearly all eyeglasses currently available are worn over the face, by putting them on the nose. However, the dominant role gained by these nose eyeglasses can not deny the existence of other eyewear products. Several hundred years ago, reading glasses were regularly held by elderly individuals to manage close-up reading materials. In detail, this original form of reading glasses was held by hand, rather than staying on the nose. Until now, there are still antique glasses in this form.
Since nose eyeglasses are the dominant form of eyewear, there is even a standard size associated with this facial part. Brand manufacturers usually imprint the size numbers inside a temple. There are typically three standard sizes suggesting the measurements of different frame parts. The second size is exactly the bridge size, such as 19. This is actually closely related with the wearer’s nose size because nose glasses will stay on the nose. Choosing a proper bridge size will ensure that the frame fits the wearer’s nose.
