Do You Need Bifocal Sunglasses?
There are millions of different makes and models of sunglasses to choose from, but if you need prescription sunglasses then you need to make sure that you have them properly prescription fitted. Some people are not even aware of what vision problems they have, which is why it is important to determine whether you require bifocal sunglasses.
What Are Bifocals?
Bifocal sunglasses are a type of prescription sunglasses that are designed specifically for people who need both near and farsighted vision correction. Bifocal sunglasses are very different from single vision lenses, as they have two corrective lenses on each side of a pair of glasses for a total of four lenses per pair.
There are actually a few different types of bifocals that are available, and only a licensed optician will be able to determine which specific type would be best for you. Bifocals have really always been designed to make all activities easier, not just reading. This includes using the computer, writing, and other activities that require close range focusing.
Bifocals contain a visible line across the middle of the actual lens, which separates the two focal portions. Eye care professionals will work with you to decide which shape should be used for the near vision focal segment, and options include a half-moon or circular shape.
Getting Your Glasses
If you have determined that you do in fact need bifocal lenses and are interested in getting bifocal sunglasses, the next step is for you to decide on a pair of frames. There are some great options out there, including names like Nike, Prada, Versace, and Chanel. More than anything it will depend on how much money you are willing to spend, because the better the brand the more expensive they are going to be.
There are a few things that you should consider when looking for a pair of bifocal sunglasses. One of the most important things you can do is actually lift them up and get a feel for them. You want the glasses to be heavier, as this will mean that they are made of a higher quality material. The cheaper glasses are always made of a plastic or similar inexpensive material, and although some of them are very attractive they tend to bend and dent more easily and will not last as long.
You also want to consider aspects such as your nose shape, in order to find the most comfortable pair of glasses.
