We Bought & Tested the Best Selling Adjustable Glasses, Here's Why Flex Focus Is #1
I’ve had to wear prescription glasses for as long as I remember. And as I got a bit older, my vision got worse and worse. I always had to carry multiple pairs of glasses with me in order for me to drive or use the computer effectively.
Obviously this annoyed the crap out of me, so when I was tasked with testing and reviewing 2025’s adjustable strength glasses, I was really excited. Could I really only have to use 1 pair of glasses for all my activities?
During my research, one brand named “Flex Focus” kept popping up on social media and online review forums. And with over 2000+ positive reviews, I had to see what the hype was about…
Setup & Testing
I received the Flex Focus Glasses in a couple days after ordering, so we were already off to a good start. Nobody likes to wait a month just for their order to arrive from China.
The setup time was very simple and quick. They come ready to use, all you need to do is put them on and adjust the lens strength to your needs. I was really pleased with how easy it was to get started, as some of the other products I tested had complex and long setup times.
Now it was time for a more comprehensive evaluation and testing of the glasses. Here are the results:
Adjustable Lens Strength – The most important perk that Flex Focus specs can offer is the fully adjustable lens strength feature. This eliminates the need to carry several pairs of glasses to meet your near-sighted and far-sighted needs. Additionally, the user controls the strength changes instead of relying on “automatic” adjustments.
Large Diopter Range – Many similar models promising full strength control only offer a very limited range of lens strength. Flex Focus completely blows everyone out of the water with an impressive range of -6 to +3 diopters. This makes the Flex Focus glasses great for many users of various ages.
Sturdy and Lightweight – A durable frame is a must because many glass wearers carry their pair around and travel with them. Flex Focus glasses do have a plastic frame. However, the material has been treated to withstand any bumps or bends the glasses might sustain in your pocket or suitcase.
Individual lens adjustment – The Flex Focus lenses can be adjusted separately. This is an exceptionally important feature for most glass wearers, who have two different prescriptions for each eye.
Glowing Customer Reviews
Another thing we loved about Flex Focus Glasses is just how great their customer service is. You can reach them via email or phone if you need any help. We called anonymously multiple times and the average wait times were just 3 minutes.
Flex Focus Glasses claims to take their customer satisfaction seriously and it certainly shows. Here are some reviews we found online:
“I had cataract surgery last year… one eye is for distance… other eye is for up close. I love my vision now, but when I read, at length, I found I needed a little help, but the readers that I bought didn’t actually work too well. I figured I’d try these, seeing as they supposedly adjust themselves. In actual fact, they seem to do just that! I’ve only had them for a few days, but so far, I’m quite happy with how they work!”
★★★★★
– Timothy R.
“I bought these, hoping to use them for up close reading and small craft work, I absolutely love them !!! They are just what I needed. I have mono-vision, and these help tremendously with that up-close focus work and with the in-between. So thank you to whoever finally developed these!!!”
★★★★★
– William S.
“I went in and got really expensive glasses that are really cute, but the main thing I can’t see is when I’m reading. I tried a few others that worked ok, but some gave me a headache. I don’t know why, but these really work! I find it strange that no one else has picked up on this. I have bought 2 pairs so that I can grab them whenever needed.”
★★★★★
– Katrina M.
It’s clear that Flex Focus is developing a cult like following all over the US.

Frequently Asked Questions
With the rise in popularity, our readers have emailed us many questions about the Flex Focus Adjustable Glasses. Here are some of the most commonly asked ones:
These glasses work by using either sliding lenses that change the lens power or fluid-filled lenses where the prescription is adjusted by increasing or decreasing the amount of fluid in the lenses. This adjustment alters the curvature of the lens, thus changing the focal length and allowing for clearer vision at different distances.
Flex Focus Glasses are particularly beneficial for individuals with presbyopia, a condition common in people over 40, where the eye’s lens loses elasticity, making it difficult to focus on close objects. They are also useful for those who have varying degrees of vision throughout the day or for those who do not have access to an optometrist for a regular prescription update.
The method of adjustment varies by the design of the glasses. Generally, there will be dials, sliders, or knobs on the frames that you can move to adjust the focus until you achieve clear vision. It’s important to start with the glasses at the lowest setting and gradually increase until you reach the desired clarity.
No, you do not need a prescription. Flex Focus is available over the counter to anyone. If you already have a prescription, Flex Focus can adjust between -6 and +3 Diopters.
How Can It Be So Affordable?
The big name brands spend billions on fancy advertising (e.g. $6.5 Million for a 30 sec SuperBowl Ad) and bonuses for their greedy CEOs. Guess who’s paying for that in the end? The customer!
Instead, Flex Focus doesn’t run many ads and instead relies on word of mouth referral sales from their customers. That and selling mostly through their online store allowed them to keep costs lower than the competition.
Don't Fall For Copycats!
BEWARE of copycats — they DO NOT use the same adjustable lens technology as the genuine Flex Focus Glasses! Only buy the Flex Focus Glasses from the official site listed below!
