Bifocal and progressive lenses are two of the most common types of eyewear for people who want to improve their vision. You might be wondering why many people go for these options. This article will explain how bifocals and progressives work, along with their pros and cons.
Bifocal lenses
Bifocals are the most common type of lens with two different optical powers. Bifocals have a top portion that is used for distance vision, and they also have a bottom portion that is used for near vision (reading). Bifocals are also called multifocal lenses. Many people find that bifocal glasses can help them to see at both distances without having to change their browline glasses every time they need to move from one task to another.
Who can use bifocal glasses?
Bifocals are the best choice for people who have trouble seeing both far away and up close. They’re also great for presbyopia, which is a condition that makes it hard to see close up over time. Bifocals are very common because they help with multiple vision problems, even if you don’t really notice them as a problem.
How do progressive lenses work?
Progressive lenses are made of two different lenses: one lens is for distance vision and the other one is for near vision. The lenses are designed to be placed in front of the eye and aligned to your eyes. They have been designed so that they give you clear vision when you look at objects that are far away, as well as when you look at close objects.
The progressive lens will have its highest point of correction on the part closest to your nose while its lowest point of correction will be on part farthest from your nose.

The benefits of progressive lenses
Progressive lenses are more expensive than bifocal lenses because they have a larger area of the lens that is not clear, making them less suitable for driving. However, they are easier to read and more comfortable than bifocal glasses. Progressive lenses can be worn while reading or performing other tasks that require close vision with ease, so you won’t need to take your glasses off when you want to do something else. If you often find yourself taking off your glasses in order to read something small or far away, then progressive lenses are likely the best option for you.
Who should wear progressive lenses?
Presbyopia. Progressive lenses are ideal for people whose eyesight is changing with age. If you’re over 40 and find that it’s hard to read text on a screen or see the hand of your watch, but you have no other issues with your vision, progressive lenses might be right for you.
Astigmatism. If one or both of your eyes have astigmatism (an irregular curvature of the cornea or lens), non-progressive glasses may not be able to correct this problem as effectively as progressive ones can—which will make seeing in certain directions more difficult than others.
Bifocal and progressive lenses have the same purpose, but they are different from each other.
When you hear the words bifocal lenses and progressive, you may think they are synonyms. But these two types of lenses are actually very different from each other. The main difference is that while both have special lines that divide the lenses into two sections (called fields), only progressive glasses have a clear border between those fields. Bifocal glasses do not have such a line, so it can be hard to tell which area of your vision is being affected by each lens.
Bifocal and progressive lenses are the best options for people who have trouble focusing on objects close to their eyes or far away. They provide clear vision while also helping you see clearly at night or in dim light conditions.
