As we get older, our eyes become weak and lose the ability to alter their focus from distant objects to close ones. This is when you will have a problem while reading the newspaper or the menu card unless you hold them away from your eyes. This condition is called Presbyopia, a natural phenomenon, which happens to almost every person in their 40's. There are Bifocal Contact Lenses that are designed to provide better vision to those suffering from this problem.
Before 1947, people used bifocal spectacles or glasses to deal with Presbyopia. Now, several manufacturers of contact lenses specialize in bifocals, but bifocal contact lenses are not for everyone. Some might find problems adjusting the lenses or finding a good vision with them. To find out if the bifocal lenses are fit, you need to determine your normal vision without lenses and other visual needs first. The good news about these bifocal lenses is that, if they suit your eyes, then they can not only make your vision better but would also make you look better.
There are various types of contact lenses. Some are made of soft materials, while some are of rigid gas permeable materials. Some Bifocal lenses can also be worn for a specific period and replaced by fresh lenses at specified intervals, sometimes even daily.
Some Presbyopia prefers a lens that can correct both distance and near vision. Such bifocal contact lenses are designed with a distance and a near portion. When you look through the upper portion of the lens, you can see the distant objects. Similarly, when you look through the lower portion, you can see the near objects. These bifocal contact lenses are known as segmented lenses.
While segmented contact lenses provide you an alternating vision, there is a different kind of bifocal contact lens that offers a simultaneous insight which allows both far-away and near items to be in focus at the same time. These lenses are designed in a manner where the near and the distance correction are put in concentric rings. But all wearers cannot adapt to this type of vision. Other types of bifocal Contact Lenses include Aspheric contact lenses and a Diffractive contact lens.
There may be many alternatives to the bifocal lenses, which are much cheaper and takes less time to adapt, but once you get used to wearing the bifocal contact lenses, you are likely to prefer it that way. If you are fond of Frequency 55 lenses, you should know that Frequency 55 discontinued, but there are many replacements of this option right now in the market, which are worth trying.
