As age catches up your eyes will become less flexible and so close up objects will not be in focus. This common vision problem is known as presbyopia, and it is one of the most common eye conditions. If you are lucky enough not to be already wearing glass, then all you have to do to solve this problem is to buy some reading glasses. If you already have glasses, then you need to switch to bifocal or no line bifocals that are also known as progressive lenses or multifocal lenses.
The no line bifocals are the most popular type of glasses that are used by people with presbyopia. Their popularity stems from the fact that they have many advantages over the traditional bifocals. Understanding what they are will help explain why their popularity has been on the increase over the years.
Unlike the regular bifocals, the progressive lenses have many focal distances. The distances depend on where you look out for. This makes it possible for the user or wearer to have a clear vision at all distances that are far, near, intermediate ad anything in between. Since these multifocal lenses have multiple focal zones, it is easier for the user to adapt to them than bifocals that only have two focal zones.
Just as the name suggests, these lenses eliminate the visible lines that are characteristic of traditional bifocals and trifocals. This helps to hide the fact that you need reading glass and also makes you look younger. In fact, some people claim that wearing this type of lenses can make you look half your age. With these glasses, nobody will know whether you are wearing them as a fashion accessory or due to presbyopia.
Advantages of No Line Bifocals
Besides from the obvious commercial advantage that you get from these lenses they also provide a better and a more natural correction of presbyopia. This is especially so when compared to the traditional bifocals and trifocals.
With no line bifocals, you can look up and see clearly across a room or view a distant object. These glasses also allow you to look ahead to your computer that is at an intermediate distance and look down to read a book comfortably through the near zone of your lenses.
These lenses eliminate the annoying “image jump” problem caused by trifocals and bifocal lenses. When using bifocals or trifocals, images seem to jump as your eyes move past the boundary between distance and near parts of the lens. For no-line bifocals, the transition is seamless and smooth as the lenses let you change your focus from distant to near and back again without experiencing any image jumps.
These lenses are more technologically advanced and sophisticated than most types of glasses. In fact, these lenses are the closest thing to a natural youthful vision that you can ever get if you are suffering from presbyopia. These lenses will provide you with an uninterrupted view of the world with a gradual and almost unnoticeable transition from far to near and anything in between. All this is achieved without the traditional bifocal line that most people see as ugly and a sign of aging. However, these lenses are more expensive than bifocals since they use a more advanced technology.
