Various types of glasses are available for different type of people. These types are in demand by different age groups. Talking about the bifocal eyeglasses, these glasses are normally used by the old age people. Considering the current trends in eyewear industry; the rimless, heavy dark frames, smart and sensitive frames- these are some of the common types of eyeglasses used all around the world in these times. Bifocal is not a new concept, it’s being used by elderly people for many years. Basically, it is designed in such a way that people wearing it can see things at different distances, like from the upper portion they can see far off objects and from the lower side they can see the closer objects, that is basically used for the reading stuff. The D shaped portion at the lower side helps the people working very cautiously. Thus, this extra portion for short-sightedness might be a very little part of the total eyeglasses or it can be a bit larger in an area.
Bifocal eyewear- suitable for multi purposes:
To decide upon the fact that whether a person needs to wear a bifocal eyeglass or not depends upon the person who is going to opt for it. Mainly the adults who feel no longer easy to do the work comfortably on their own, and who have the problem of short-sightedness preferably choose the eyewear of bifocal sort. This problem is commonly termed as presbyopia, and because these eyes wear is just not only the solution for the short-sightedness but is also used for farsightedness. It helps the myopic patients also.
So even if a person is using the computer or if he is a book worm, he needs to have this eyeglass, because of the reason that it provides the wearer the facility of having a clearer and wider near vision. This facility helps the effort of the wearers’ focus to be adjustable, in watching both the far and nearer objects at one time. The various shapes of these glasses include:
• The D portion at the bottom of the eyeglasses.
• A circular shaped portion.
• A rectangular shaped portion at the lower side of the glasses.
• The complete lower half of the eyeglasses.
The major advantage of using this type of glasses is the easiness; people do not have to carry two eyeglasses at a time for the long and short-sightedness. Using this type of eyewear might be a problem in the beginning; it takes time to get adjusted to something new. People might be reluctant to select such a product because it gives quite a serious, boring, and adult look. But the benefits, the convenience, and the portability are changing the tastes of the customers. Doctors are also prescribing these types of glasses for their patients. Even the people who do not need prescription eyewear, but for the reading purpose they just buy nonprescription bifocal glasses. Thus, it’s the personal decision whether to purchase bifocal glasses depending upon the individual needs.
