Among the many questions we get here at 39DollarGlasses.com, one of the most common involves uncertainty when it comes to lenses. Those who need eyeglasses for both distance and reading have the option to wear either progressives or bifocals. If you often find yourself asking what the difference between these two types of lenses are, you’re in the right place.
Bifocal lenses are created with two separate areas of vision correction, which are divided by a line that runs horizontally across the bottom of the lens. To keep it simple: the top half of the lens is used for distance and the bottom portion is used for closer vision. We carry flat-top 28 bifocal lenses, which means the closer vision portion of the lens is 28 millimeters wide and shaped like a sideways letter “D.” There is also a different type of bifocal where the dividing bifocal line goes all the way across the lens, this is called an executive line bifocal. This type is not offered on our site but you are able to purchase it by calling in. Both these lenses are noticeably different than single-vision lenses as the lines are visible and defined.
If you’ve ever heard of the term “no -line bifocals,” it is simply another term used for progressives. You may also hear other terms used for progressives such as “no-line trifocals” or “vari-focals.” Similar to bifocals, progressives provide a range of vision that gradually progresses from distance to near from top to bottom, without a line or shape at the bottom of the lens. This is a great option for those who need the strength of bifocals but do not want the noticeable appearance of them – people will never know you’re even wearing multifocals.
Adjusting to Progressives:
It may take some time for you to get used to the adjustment of wearing progressives. Because you are adapting to a new type of lens, it may take a few minutes, days, or even weeks to feel completely comfortable. This is why we offer a great warranty policy on certain progressive lenses, this gives you time to adjust to your new prescription without the pressure of a short return deadline. Our team has created a tutorial video to show you how to adjust to your progressive lenses.
Will they be too expensive?
While bifocals and progressives may cost you a fortune elsewhere, our multifocal lens packages start at just $119 in a $39 frame. We have multiple packages for each type of lens, which are all polycarbonate lenses which are customizable with different ad-ons such as anti-glare coating or tint.
Overall, either one of these lens options are an excellent choice for vision correction. They are both comfortable lenses that will help you see objects both near and far much more clearly. Do you need glasses for distance or reading only? No worries – just select single-vision lenses for either full-time wear or reading.
