Bifocal glasses feature a bifocal lens with the top half of the lens correcting for distance vision and the bottom half correcting for nearsightedness; if you need to correct both distance and nearsightedness at the same time, bifocals are perfect. These bifocal reading glasses are designed to be used as both reading glasses and standard prescription glasses, making it easy to use one pair of eyeglasses for two purposes.
Bifocal reading glasses work by providing two different prescriptions on a single bifocal lens. If you look closely at these lenses, you will notice what appears to be a short line down the center, which is actually a small protruding lens that attaches to the larger lens to provide the degree of prescription needed for reading or seeing near. The protruding lens sits on the lower part of the entire lens and is used to aid in reading, while the upper part of the bifocals is primarily used for distance and everyday regular prescription.

Reading glasses generally refer to eyeglasses with prescription lenses for reading and most up-close use; these prescription glasses can only be used when looking at close objects and are generally required for presbyopic patients. Bifocal glasses, on the other hand, as the name suggests, have two focal points on one lens and can be used for both distance and close up viewing. Bifocals are the perfect solution for both nearsighted and farsighted patients who only need to wear one pair of prescription eyeglasses.
In general, whether you wear reading glasses or bifocals depends on two things. First, your doctor's optometry results and eye prescription order recommendations. Second, whether you need to use both near and far vision most of the time you are there, such as when you are going about your daily work and life. So, now you know how to choose.
