Single Vision Vs Bifocals Vs Varifocals-A Simple Guide
Share
When you get your eyes tested, glasses are usually fitted with single vision lenses by default. Additional options such as Anti-Reflection Coating or Blue Light Protection can be added if needed. But sometimes, you’re told that Bifocals or Varifocals may suit you better-and that’s where confusion often starts. In our Manchester lab, we see these as the levels of vision; finding the right one is like finally getting the seat adjustment in your car exactly where you want it.
At a glance:
Single vision lenses correct one distance, bifocals offer two distinct zones, and varifocals provide a smooth transition between multiple distances. Sapphire Optics fits all three lens types in-house to match different lifestyles and prescriptions.
Single Vision (1.5) Lenses
One distance. One purpose. Single vision lenses correct vision at one viewing distance only. They’re the most straightforward lens option and are included in the price of your frame at Sapphire Optics.
They’re commonly used for:
-
Distance (driving, watching TV)
-
Reading (books, phones)
-
Computer or screen use
Pick these if: You only struggle at one distance, you wear glasses part-time, or you are wearing glasses for the first time and want something uncomplicated.
Bifocal Lenses
Two clear zones — no guessing. Bifocals are designed for people who need help with both distance and near vision. They contain one section for distance and one section for reading, with a visible line separating the two. Many still choose them because they offer clear, immediate focus at each distance without blending zones.
Pick these if: You prefer clearly defined viewing areas, you want instant reading focus, or you’ve worn bifocals before and liked them.
Varifocal Lenses
Multiple distances in one lens. Varifocals (also called progressives) allow you to see near, intermediate, and distance—all within a single lens. Instead of a line, the prescription changes gradually from top to bottom. They do take a short adjustment period, but once adapted, many people find them incredibly convenient.
Pick these if: You switch between distances frequently (like looking from a laptop to a meeting), you want one pair for everyday use, and you prefer a seamless look.
Which One Is Right for You?
There’s no best option—only what fits your life. Ask yourself:
-
Do I wear glasses all day or only sometimes?
-
Do I mostly look at one distance, or several?
-
Am I switching between reading, screens, and distance throughout the day?
-
Do I want clear separation, or a smooth transition?
You Don’t Have to Decide Alone
Lens choices can feel overwhelming-especially when terms are thrown around without explanation. Whether you’re ordering new glasses or using our Reglaze Only service to upgrade frames you already love, we take the time to check prescriptions properly and make sure the lens choice actually suits how you’ll use them.
No pressure. No rushing. Just the right setup for your eyes.
FAQs
What is the main difference between these lenses?
Single vision corrects one distance, bifocals correct two distances with a visible line, and Varifocals correct near, intermediate, and distance in one seamless lens.
Which lens type is easiest to adapt to?
Single vision is usually instant. Bifocals are also straightforward, while Varifocals may take a few days to two weeks for your brain to map out the different zones.
Are Bifocals outdated compared to Varifocals?
Not necessarily. Some people prefer the wide, dedicated reading window of a bifocal over the gradual shift of a varifocal. It is all about personal comfort.
Do Varifocals take time to get used to?
Yes, a short adjustment period is normal and usually settles within a few days of consistent wear.
How do I know which lens type is right for me?
It depends on your daily habits-if you are constantly swapping between walking glasses and reading glasses, it is likely time to consider a multifocal.
Can I change lens types without changing my frames?
Yes. If your frames are still in good condition, our lab can fit them with any of these lens types through our Reglaze Only service.
