What is the difference between progressive lenses and varifocal glasses?

None — 'progressive lenses' is the American English term and 'varifocal glasses' is the British/Australian English term for the exact same product: a single lens that blends distance, intermediate, and reading power without a visible line.

Why do some people feel dizzy with progressive lenses?

Dizziness usually comes from an imprecise fitting measurement or an adjustment period as your eyes learn to use the different zones of the lens. Correct pupillary distance and fitting height measurements, done by an experienced optometrist, prevent most of this discomfort.

Where can I get progressive lenses fitted properly in Bangkok?

Optical X at Riverside Plaza, Floor 2, Bangkok, offers a level of eye exam and precision progressive/varifocal lens fitting that most patients have never received before with an English-speaking optometrist and a 30-day free adjustment guarantee.

Progressive Lenses in Bangkok,
Fitted to Actually Work.

Whether you call them progressive lenses or varifocal glasses — same lens, different side of the world — they're a single pair of glasses that blends distance, intermediate, and reading vision without a visible line. Done well, they're effortless. Done poorly, they cause dizziness, headaches, and glasses you avoid wearing. If a past pair of progressives let you down, the problem was almost always the fitting, not the lens.

The Optical X Difference

Why Fitting Matters More Than the Lens

Two people with identical prescriptions can have completely different experiences wearing progressives — because fitting is where most Bangkok optical shops cut corners. Here's what a fitting looks like when it's actually done properly — a service you've never received before.

View through a progressive lens showing the clear reading zone at the bottom and the blurred distortion zones at the edges — A precisely fitted progressive lens — the clear zones line up exactly where your eyes naturally look for distance, computer, and reading.

An Exam You've Never Had Before

A full refraction and visual assessment, not a five-minute autorefractor reading. We confirm your add power is exactly right before any lens is ordered — the single biggest cause of progressive lens problems is an inaccurate prescription.

Precision Fitting Measurements

Pupillary distance and fitting height are measured with you wearing your actual chosen frame, in your natural posture — not estimated. A few millimeters off is the difference between smooth transitions and constant dizziness.

Explained in Plain English

Our optometrist walks you through how to use your new lenses — where to look for distance, where for your phone, where for reading — so the adjustment period is shorter and less frustrating.

Common Concern

Worried About Dizziness?

If a previous pair of progressives made you dizzy or gave you headaches, that's a fitting problem, not a reason to avoid progressives altogether. A short adjustment period is normal as your eyes learn the lens — but persistent dizziness almost always traces back to incorrect measurements or a rushed exam, both of which we take extra care to get right.
