Love them. The protective case is made well. Work great. Make great gifts for friends who use readers. You just have to get the strength or magnification from them. If I have my car keys. I have my glasses. They hook on well and take little space. Review: Always with you, never lost or forgotten, super convenient, excellent warranty and customer service - I bought a pair of ThinOptics Keychain Case and Readers in July of 2023. I love them, they're so convenient and I always have them handy since they're with my keys. Then, towards the end of October, I noticed one of the nose pieces had broken off, which isn't a big deal for me as I only use them for very brief periods to read small print. Then in early November I noticed that they wouldn't stay clipped into the keychain case, and would easily fall out. I submitted a replacement request through the ThinOptics website and within the same day I received a response asking for the shipping details to send the replacement. That's how customer service is done! Thank you ThinOptics! ## Features - ULTIMATE PORTABILITY & ACCESSIBILITY: Say goodbye to the frustration of misplaced reading glasses.

I love them, they're so convenient and I always have them handy since they're with my keys. Then, towards the end of October, I noticed one of the nose pieces had broken off, which isn't a big deal for me as I only use them for very brief periods to read small print.

Thank you ThinOptics! ### ⭐⭐⭐⭐ A very practical and useful product *by T***Y on January 24, 2017* First time I bumped into armless reading glasses was at an eyeglasses store in France. The brand was Nooz. I was so impressed by it, I bought two pairs to bring back to the US and found that they are so useful, I need more of them! Unfortunately, Nooz cannot be found in the US. So I looked for alternatives. Then I found ThinOptics. Material wise, ThinOptics has decent quality plastic optics. The optical performance is more than satisfying. The construction of the bridge, however, is kind of suspicious. It is basically a flexible wire with one of the lenses molded on each end. But it is holding up pretty well after 2 months of light use. The good news is ThinOptics will replace your glasses for free if they break. So I am willing to give it a try. What makes ThinOptics great is also the bridge. It is so flexible that the glasses can be folded in half and packed into a key chain size case. OK, it's slightly bigger than a regular key chain, but I have no problem carrying it around in my pocket. The convenience more than makes up for the slight compromise in the construction. Other notes: The height of the lens is a bit short because of the compact design. It is no problem for reading books or newspapers which are usually placed at a lower level. If you plan to use it on computer screens which are about eye level it might be less comfortable. Also, the nosepad surface appears to be made of sandpaper. It could leave a scratchy feeling on your nose after wearing it for a while. All and all, I think ThinOptics makes the right compromises in their design and delivered a very practical and useful product with good quality. ## 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://chile.desertcart.com/products/33934245-keychain-case](https://chile.desertcart.com/products/33934245-keychain-case) --- *Product available on Desertcart Chile* *Store origin: CL* *Last updated: 2026-10-05*
