Great quality lenses and excellent service
I needed progressive glasses asap and rolled the dice on this because I was out of options before an event where I desperately needed to use a new prescription. Their site is super easy, very clear, incredibly communicative when I needed to swap a customization out after purchase, and with that delay my glasses came in 5 days (which included a long holiday weekend. ) They fit great, look cute, and the field of vision for each part of the progressive lenses is great! I hope they hold up long term - I’m totally ordering from them when I can afford to get sunglasses as well. ... Read more

Great customer service and great glasses
This is the best customer service ever. The glasses are just as described and perfect!!
The glasses ended up in the wrong location (my fault) and I did not have to make one phone call. They contacted me through text and we resolved the issue in minutes and the glasses arrived overnight to the right location. ... Read more

I can’t say enough good
I can’t say enough good things about Overnight Glasses! From start to finish, the process was seamless. I didn’t have a current pair of glasses to reference, but the site made it incredibly easy to order from scratch. The tools, instructions, and guidance were so user-friendly—it gave me everything I needed to confidently place my order.
What truly impressed me was the incredibly fast turnaround time. I received my glasses faster than I ever thought possible, and they were perfect right out of the box. The fit was excellent, and the quality is top-notch—better than some I’ve paid much more for elsewhere.
If you’re looking for reliable, high-quality glasses with lightning-fast service, look no further. Overnight Glasses exceeded every expectation! ... Read more

Pleasantly surprised.
I am extremely myopic and the glasses I have purchased in the past clearly reflected that. However, when I received these I was pleasantly surprised by the craftsmanship and that they were aesthetically flattering.

Great Service - Great Website - Excellent Product - FAST!
My Great Pyrenees puppy "brought me" my expensive Maui Jim prescription sunglasses w/ anti-glare and polarized - the teeth marks prevented me from bringing them on a destination wedding trip in 4 days! Now what??? I found your website and was skeptical of what quality the product would be and can they really be here in 2 days? I was so impressed that every aspect of navigating the website, choosing my style, lenses, features etc. was so easy!! Then when I received the glasses on time and they fit and felt perfect, and my prescription was correct, I couldn't be more satisfied! Thank you!
Excellent service, very fast, fantastic fit and quality. ... Read more

A Risk Worth Taking!!
Was skeptical.
Not just on the production side, but on my own measurements & guesstimates of style & fit.
My glasses arrived 2 days earlier than expected. And they are SUPER!!
I'm thrilled. And, I can see clearly.

Quick, Easy, Efficient!
I sent both of my frames (separately) to Overnight Glasses and both experiences were so quick and easy! It was my first time using Overnight Glasses and I was pleasantly surprised at how communicative they were.
I received an email and had questions, so I called Overnight Glasses up and immediately an actual person picked up, which was so refreshing. My question was answered within a minute.
Overall great experience! ... Read more
