Bifocals vs Progressive Lenses - What is it
by Vicci Eyewear on May 11, 2022
Understanding the fundamental differences between bifocals and progressive lenses is the first step in selecting the best solution for your eye health needs.
As you reach middle age, you go to your doctor for a routine checkup and are instructed to get a vision exam. You think, “Why now? I've been seeing perfectly well for years.” But then it dawns on you - this exam is related to your work. And suddenly, it's no longer about 20-20 vision; instead you start to wonder how sharp your peripheral vision really is, how far you can read from the computer screen and whether or not you should be wearing bifocals (or did they say progressive lenses?)
What Are Bifocals?
Bifocal lenses are the best prescription lenses that are currently available in the market. They were invented by Benjamin Franklin in the 18th century, and they have become one of the most popular types of eyewear in the United States.
Bifocal lenses are used to correct vision problems such as nearsightedness or farsightedness. Bifocals work by combining two different kinds of lenses: a convex lens for distance viewing and a concave lens for near-vision tasks (such as reading). Most bifocals come with one set of spherical contacts that are used for distance viewing; however, some bifocals come with additional sets of contacts for reading or computer use.
Bifocal lenses come in many different styles and shapes. Some bifocals are shaped like a pair of traditional glasses, while others have rounded edges and no frame at all. The type of bifocal you choose will depend on your needs and preferences.
What Are Progressive Lenses?
Progressive lenses are a type of eyeglass lens that have an added feature, which is a line of vision that is not as close to the wearer's eye as it is for the other parts of their field of vision.
Progressive lenses are used to treat people who have difficulty seeing objects close up and far away. This condition is called "presbyopia." A person with presbyopia struggles to read small print or see things in the distance, while still being able to see clearly at intermediate distances.
Progressive lenses are also called trifocals or no-line bifocals
Difference Between the Bifocals and Progressive Lenses!
Bifocal lenses offer two prescriptions in one lens, while progressive lenses offer a smooth transition for users with multiple prescriptions. Lenses with two prescriptions are generally used for those with presbyopia, an age-related condition that affects the ability to focus on nearby objects. Bifocal lenses can be identified by the visible line separating the two different prescriptions. Progressive lenses do not have a visible line and provide a continuous progression of increasing magnification so that users can shift focus from near too far.
Benefits Of Progressive Lenses Over Bifocals.
When you're in need of a new pair of eyeglasses, it's important to consider all of the different types available. Many people believe that bifocals are the best option for correcting vision problems but this is not always the case. In fact, progressive lenses can be a better choice for many people because of their advantages.
Progressive lenses are multifocal lenses that correct your vision at multiple distances without any visible lines or dividing segments. They help you see clearly both up close and far away without any annoying lines in your field of vision. This is especially important when looking straight ahead at an object or person as well as when reading text on paper or computer screens. In addition to convenience, there are other benefits associated with using progressive lenses over traditional bifocals including:
⦁ No distortion in peripheral vision.
⦁ Improved visual comfort.
⦁ More natural look than bifocals (no unsightly lines).
⦁ Ability to see clearly in all directions, not just straight ahead.
