What Are Progressive Lenses? (And Why We Call Them Varifocals)
Share
If you’ve reached the age where you’re constantly swapping between your "walking around" glasses and your "reading" glasses, you’ve probably heard the term Progressive Lenses. At Sapphire Optics, we know that optical jargon can be a bit of a headache, so let’s keep it simple: Progressives are the ultimate "all-in-one" solution for clear vision at every distance.
In the UK, you might know them better as Varifocals. Whether you call them Progressives or Varifocals, they are designed to give you a seamless transition from the sat-nav to the dashboard to the book in your hand—all without a single visible line in sight.
At a glance:
Progressive lenses, also known as varifocals, allow clear vision at multiple distances within a single lens. Sapphire Optics offers varifocal lenses fitted in-house to provide a smooth transition between distance, intermediate, and near vision.
How Do Progressive Lenses Actually Work?
Unlike traditional bifocals, which have a distinct (and sometimes ageing) line across the lens, Progressives are a feat of engineering. The prescription gradually blends from top to bottom:
-
The Top: Corrects your distance vision (perfect for driving or watching TV).
-
The Middle: The "Intermediate" zone (ideal for computer screens or your car's dashboard).
-
The Bottom: The "Near" zone (dedicated to reading or looking at your phone).
Welcome to the "40+ Club" (Presbyopia)
Most people start looking into Progressives around the age of 40. This is usually when a natural condition called Presbyopia kicks in—which is just a fancy way of saying your eyes are finding it harder to focus on things close up. If you find yourself holding menus at arm's length or squinting at your phone, it’s time to chat with our Manchester lab about a Varifocal upgrade.
Progressive vs. Varifocal: What’s the Difference?
In short: Nothing. "Progressive" is the international and technical term used within the optical industry, while "Varifocal" is the term we use on the British high street. They describe the exact same technology. Whether you’re browsing our Men’s, Women’s or Unisex collections, you can choose this lens type for almost any frame.
Progressive Lenses vs. Bifocals
Before Progressives became common, many people used bifocals. Bifocals contain two separate prescription areas separated by a visible line.
-
Bifocals: Abrupt shift between distances; visible line on the lens.
-
Progressives: Gradual transition; no visible lines; more modern appearance.
FAQ
Do progressive lenses have a visible line?
No. They look exactly like standard, single-vision lenses. No one will know you’re wearing "multifocals" unless you tell them.
Are they difficult to get used to?
Some people need a short adjustment period. Most wearers adapt within a few days as their brain learns to use the different "zones" of the lens.
Can I put Progressive lenses in my own frames?
Yes! If you have a pair of frames you already love, our Reglaze Only service is a perfect way to upgrade to Varifocals without the cost of a new frame.
Do I need progressive lenses?
Progressives are typically recommended if you need both distance and reading correction. Once we see your prescription, we can advise whether they are suitable for you.
Can they be combined with other tech?
Absolutely. We highly recommend adding an Anti-Reflection coating or a Blue Light filter to your Progressives, or even combining them with Reactions for the ultimate all-rounder.
Which lens is best for me?
It depends on your lifestyle. If you spend all day switching between a screen and long-distance views, Progressives are usually the winner.
Bifocal or Progressive-which should I choose?
Many people prefer Progressives for the smoother transition and modern look, but bifocals can still be suitable for certain prescriptions.
Are they expensive?
Because they blend three prescriptions into one with extreme precision, they do cost more than single-vision lenses. However, they effectively replace three separate pairs of glasses, making them a smart long-term investment.
