Why would I need to get Bifocal Sunglasses?
Many people do wonder why they might need to wear bifocal sunglasses. Bifocal lenses contain two separate and different areas for viewing purposes. Usually, this is the upper and lower portion of the lens, with the upper portion being used for distance vision and the lower portion of the lenses being used for near vision. The reason why someone needs a bifocal lens is that they need to have a prescription for far vision and for near vision in a single lens.
An optician might recommend bifocals in order to reduce the eye strain that you suffer when you are doing close work, which can lead to some progressive near sightedness. For near-visual purposes you would not want to have a single distance prescription, as it would be pretty inappropriate for any visual activities. So bifocals get prescribed to help you focus and to aim your eyes more effectively.
Sometimes you may have trouble when playing golf, in that you don’t need help with items that are close to you, such as a golf ball, but you do need help with spotting items in the distance, like a flag, or bunkers, or any other features. Bifocal sunglasses would enable you to help you to focus on items close to you and then help you to focus on those distant items as well.
When you then have to look at objects that are very close to you, you may suffer from strabismus, which is basically cross-eyes. Bifocals can help you to aim your eyes correctly in this situation as well.
What we are not saying is that if you are prescribed bifocals it means that you possess bad eyesight. What it means is that it is possible for you to get the ideal correction for distance and near vision in one pair of sunglasses. When you go to get these lenses, your optician will need to review your specific needs and then recommend the bifocal sunglasses that will meet those needs best. These sunglasses will be available in polycarbonate, which is the safest material available for lenses, and always comes highly recommended. Do take the advice of eye care professionals though, as there are so many factors involved in wearing bifocals that people who really know what they are doing can really help you.
As far as adapting to this rather unusual lens situation, you just need to wear them as much as possible and eventually your eyes will get used to it. Obviously, if the problem is found when you are a child then it will be easier for you as it generally is easier for children to adapt to changes like this.
