Frequently Asked Questions
FAQs
Will these fit over my glasses?
Fittys are designed to fit over all prescription glasses. They have fit over large frames, small frames, nylon frames and metal frames.
However, we know that fit is not just about fitting over your glasses but also about you enjoying how Fittys look when you wear them.
This is a personal issue, and we respect that!
This is why we offer free shipping on all US orders and a 90 day return policy with free returns.
If you don't like how they fit, please send them back!
What makes Fittys different?
We (the founders) tried over 40 pairs of fit-over sunglasses that were available on the market before starting Fittys. There were a few major problems we found with all existing options that we are looking to improve on with Fittys.
#1 - Lens quality. Most existing fit-over brands have a lens quality that is either poor or unknown because they don't advertise it. As the whole point of sunglasses is to put protective lenses in front of your eyes, we went with the highest quality lens provider in the world for Fittys by partnering with Carl Zeiss for our lenses. They have great clarity. They're super durable. Also, our polarized lenses have a scratch-resistant coating.
#2 Design. Which glasses you like is of course a personal choice, but a lot of the existing fit-overs in the market look like medical devices. We didn't like this. Instead of going that route, we chose to invest in design to create something more modern and timeless.
#3 Frame material. We wanted a quality frame material. We went with TR90 which can be sat on, dropped, left on a hot dashboard etc. and keep going without being damaged. (Also our frames are made of 58% biomaterial sourced from a carbon-neutral plant.)
These changes are so different that we believe Fittys is a unique and premium product in this market.
We know we're not a fit for everybody, but just wanted to explain our thoughts behind the design of Fittys and give context as to why we prioritized these differences.
Who started Fittys?
Fittys was founded by a husband and wife team that's passionate about solving this problem. We're both members of the four-eyed community and we were constantly frustrated with our sunglass options.
We have a young family and would love to see this business grow into a family business in the decades to come.
We came up with the idea in Fall of 2023 and launched on Kickstarter to a very positive reception in June of 2024. It's been very exciting since!

Can I wear these with just my contacts?
Yes! Fittys are often worn by those who aren't wearing glasses just for the style and the luxury-quality lens.
Can I wear Fittys over transition lenses?
In short, because the lenses block 100% of UV rays and UV rays are what trigger transitions to get darker, Fittys provide darkness while also stopping your transitions from getting darker. Considering this, Fittys should provide darkness while avoiding any redundant darkening.
However, for an abundance of caution, we do not recommend wearing Fittys over your transition lenses while driving.
Let customers speak for us
from 410 reviewsIt fits perfectly over my prescription glasses.
The optics are much better than the drugstore ones.
I’ve tried other “cheaper” over the glasses brands and they are not big enough since I have a wide face and therefore wide glasses. These are great!
I love I can switch back & forth without searching for the other pair. Great for just in and out of car. If I'm going to be out longer, then I switch them.
Bought these as Birthday gift for my daughter. She absolutely loves them. She wears them every where. She likes how she only needs one hand to put them on. She had shoulder surgery and can’t use one arm. She loves them fit perfectly too. Thinking about getting the night driving ones for her.
These glasses are comfortable and effective. A little snug fitting over my glasses, requiring careful placement and alignment, causing some distraction from driving or pulling over to apply. Once on, they feel good and don't slip. I wish they were a little bigger, for easy placement when driving. I would recommend these glasses. I have both sun & night vision.
I purchased two pairs of the glasses. One stays in my car and the other hoes with me anywhere else I may be going. I purchased a pair for a friend who is also ecstatic about them. I'll most likely be buying the night vision glasses to reduce the glare of headlights when driving in the evening hours.
My husband received the polarized sunglasses as a gift and absolutely loves them! The sunglasses provide excellent sun protection, comfort, and hide his prescription glasses well. Definitely a great pair of sunglasses!
As someone who wears big ole aviator frames, i had my doubts these things would fit. Nope, they fit my fat frames perfectly. They are comfortable to the point you can't even tell youre doubled up.
Fit over my regular glasses with no discomfort whatsoever. Lenses are very clear, not too dark. I got the polarized ones.
I will be purchasing another pair for my wife 😍
I was googling shades that fit over prescription glasses because my eye contacts are quite expensive..I took a chance on Fittys and the style is sleek! Selfishly I wish it came with a cleaning cloth because you can never get of them lol but seriously, great design and looking forward to more variations in lens color. I'll happily be an ambassador for this company.
I recently moved to northern Michigan in a rural area. I leave my house every morning at 5 a.m. for the gym, and it is pitch black out. I wear prescription glasses, and the glare from the occasional streetlight or headlight when it's that dark on these winding roads always made me feel a bit uncomfortable. The Fittys night driving glasses have changed the game! They fit perfectly and comfortably over my regular glasses, and instantly, my vision is as sharp as it is in the daytime (maybe sharper!) The Fittys have been a great addition, and I feel much safer driving in the dark than I used to.
I purchased both the sunglasses and the nighttime driving glasses. I am pleased with the quality and both work very well.
Oncoming headlights at night made driving kind of nerve-wracking. The night vision glasses really did the trick for me. They fit nicely over my glasses, and I keep them ready in my car.

Liked that it cut the glare but dislike the fit. My glasses are not big but the Fittys do not go over my glasses. There’s an inch between them!
The Fittys polarized glasses are OK. Light in weight which is the best feature, but also bulkier than expected. Because they sit further away than my glasses. they desperately need some system to block light from entering from the sides. So much light enters from the sides that there is still far too much glare. Perhaps Fittys needs to take inspiration from the design of many sunglasses designed for fishing. These won't be getting a lot of use from me.
