Review: Great set - I have four or five versions of these at various places - laptop case, a magnetic case that mounts to the magsafe back of my iPhone, and a few others in some other spots. They're awesomely convenient. Love the thinness, how they can be stored anywhere without bulking anything up, and they stay on pretty well considering how thin and tiny they are. Great for improving my vision for close up reading. Review: Handy. Decent quality. - First set worked well for a about five years with minimal use (maybe 1-2x per week). Would have been nice if they'd lasted longer, but they worked well enough that I bought another pair as a replacement. ## Features - ULTIMATE PORTABILITY & ACCESSIBILITY: Say goodbye to the frustration of misplaced reading glasses.

Our advice is to try 1.50 first and see if it is strong enough. If it is not, we can exchange it within 30-day at no cost to you. Let us know if you have any questions. - ThinOPTICS Customer Support **Q: Is it a common issue for the glasses to fall out of the keychain case?** A: My wife bought me a pair of these about a year ago and i love them. Id keep them in my pocket because between riding my motorcycles and driving my truck id forget them on a keychain. As for them falling out ive never had this problem. They're very secure in the locking case. So if you lose them due to this reason you didnt lock them in the case properly. **Q: Mine have gotten quite scratched and are now unusable. Do I send them in for replacement under the lifetime warranty?** A: Yeah, Good luck with that... I was told I could, so I sent in all three of the pairs I bought. That was in February, this is approaching the end of August and I’ve yet to receive the new ones or even so much as an email from the company. Pretty much a lost cause. **Q: does this include 1 pair of glasses or 2? on the thin optics website it's $24.95 + s&h for the keychain and 2 pairs.** A: Just FYI the people mentioning the 2 for 1 deal are from 5 years ago. As of 2022 the site is offering 1 for that price, not 2. I just checked. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great set *by L***E on December 28, 2025* I have four or five versions of these at various places - laptop case, a magnetic case that mounts to the magsafe back of my iPhone, and a few others in some other spots. They're awesomely convenient. Love the thinness, how they can be stored anywhere without bulking anything up, and they stay on pretty well considering how thin and tiny they are. Great for improving my vision for close up reading. ### ⭐⭐⭐⭐⭐ Handy. Decent quality. *by G***. on March 18, 2026* First set worked well for a about five years with minimal use (maybe 1-2x per week). Would have been nice if they'd lasted longer, but they worked well enough that I bought another pair as a replacement. ### ⭐⭐⭐⭐⭐ Convenient and compact *by M***4 on November 10, 2025* I have the 1.5 power. These are great. Nice and compact. They fit perfectly in my pocket and I'm going to get another set just to stash in the vehicle. I have regular progressive lens glasses that irritate my eyes if I wear them all the time, and rather than hang those on my shirt when I'm out and about, these pocket readers are the perfect solution. I haven't had them long enough to comment on long-term scratch resistance. The grip pinch on the nose works fine for the few minutes I use them, and they are not loose when shaking my head around. It does seem that they are designed for eyes that are somewhat close together, which mine are (69mm center to center). It also doesn't matter which way you put them on (no front/back). ## Frequently Bought Together - ThinOptics Keychain Case and Readers Rectangular Reading Glasses - ThinOptics Rectangular Reading Glasses --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/374985459-keychain-case-and-readers-rectangular-reading-glasses-black-lens-width](https://www.desertcart.be/products/374985459-keychain-case-and-readers-rectangular-reading-glasses-black-lens-width) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-22*
