Why it works:
Concerned they’ll take getting used to? Most customers adjust quickly thanks to the clearly defined lens zones.
Fit Tip:
Dual-Strength frames are grouped by face width — Narrow, Average, Wide, and Extra Wide.
If most glasses feel snug at the temples, try the Wide or Extra Wide section. If your frames often slip or feel loose, start with Narrow.
Not sure? Average works well for most faces.
Dual-Strength Bifocal
Two Powers, One Pair – Seamless Vision for Every Task
One Pair of Glasses. Two Clear Zones. Zero Switching.
Dual-Strength Bifocal Reading Glasses are designed for people who move between reading, screens, and distance all day — and don’t want to keep taking their glasses on and off.
Glasses designed around what you love to do — not just what you need to read.
If you’re tired of juggling two pairs of readers — or struggling with progressives that never quite feel right — Dual-Strength Bifocals offer a simpler, more predictable solution. You get a dedicated magnified reading area and a clear upper zone in one comfortable frame, so your vision keeps up with real life.
“I cannot believe how happy I am about my glasses —
you have changed my life, I mean it!”
— T. Coe

How to Choose Your Strengths
Choosing your powers is easier than it sounds. Here’s a simple way to think about it:
Step 1 – Start with what you already wear.
If you use two pairs today — one for the computer and one for reading — those are the same two strengths you’ll use in your Dual-Strength lenses: computer power on top, reading power on the bottom.
If you currently wear just one pair of readers, use that strength as your bottom (reading) power.
Step 2 – Choose a milder power for the top.
The top of the lens is made for computer and mid-range (arm’s-length) vision, so it should be weaker than your reading strength — similar to your “computer pair” if you already use one.
Step 3 – Why the difference matters.
Dual-Strength lenses work best when the top is at least 1.00 diopter weaker than the bottom.
This creates a smooth, comfortable transition from computer distance to close-up reading — without eye strain.
Step 4 – Fine-tune for your daily habits.
If you spend more time on the computer than reading, choose a gentler top power for relaxed, sustained clarity.
Here are a few example combinations that follow the required 1.00 diopter difference and offer smooth dual-distance clarity:
| Your usual readers | Suggested top (computer) | Suggested bottom (reading) |
|---|---|---|
| +2.50 | +1.50 | +2.50 |
| +3.00 | +2.00 | +3.00 |
| +3.50 | +2.50 | +3.50 |
| +4.00 | +3.00 | +4.00 |
