  • Fantastic!
Color: Black Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 1.5 x
These are great, lightweight and unnoticeably comfortable, like, -I forget I'm wearing them! Great design, simple and sophisticated looking yet a wonderfully reinvented marvel in itself.

  • We both use these key chains now!
Color: Black Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 2 x
The item arrived on time and undamaged. I ordered two of these handy key chains; one for me, one for my partner. We're both in that fun phase of middle age where a restaurant receipt in a low-light restaurant setting is like trying to read glyphs on a cave wall in by torch light. He is not a fan of the pince-nez concept, and was initially resistant in fear of being judged and tortured by his squad. However, he's in the trades and the feature he resisted was trounced by the convenience of having them along for every ride in the car. On the job, it spared him several trips to his truck for his cheaters to read dusty fuse boxes in basements. Now, he wants my set as a backup. Not gonna happen. The key chain case is not too bulky. Putting the glasses back in the key chain does take some finesse and practice, but is very easy once you give it a few practice runs. I had a Sofia Vergara set of similar specs that folded into a credit card sized case that never made it into my wallet or purse. There's no way to leave home without these. The price is right and you'd never know the lenses are plastic when you use them. It's convenient and surprisingly sturdy quality. Definitely a great value and I'm glad we both have them on hand. ... show more

  • Handy and works well after a slight modification
Color: Black Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 1.5 x
I'm at the point where it's nice to have readers available for that darn small print in dim light that I seem to encounter more and more often. The ThinOptics are the smallest and easiest to carry that I have found. One really great feature is that the lenses are ground so that there is no front or back. You just put them on and read. The case is a clever bit of kit and with very little practice you get the hang of sliding them in and out. My only gripe was the nose pieces. As received from the box, they were very, very rough--almost like sand was embedded into them. I'm sure this is to help them stay in place when you move your head, but I found it very uncomfortable to wear for more than a few seconds. I fixed this by taking a very fine sandpaper (600 grit) and lightly burnishing the nose pieces until they still held in place but did not feel like they were digging in. I haven't had them long enough to rate their scratch resistance, but at the moment I'm finding the folding, flat design excellent for EDC. ... show more

  • Always with you, never lost or forgotten, super convenient, excellent warranty and customer service
Color: Silver Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 1.5 x
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! ... show more

They work really well and super light weight. Can take on long bike ride and be able to read my phone if stranded, puncture etc. Awesome 👍

  • They're OK for backup readers
Color: Black Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 2.5 x
These are good for keeping in your pocket for the times I forget (lose) my actual comfortable readers. They work ok, they pinch the bridge of the nose in order to hold on, so it is to be expected thet they "pinch" your bridge and can become irritating/uncomfortable. They are not for extended use. The magnification is slightly distorted, but not enough to return as "not useful" I still keep these in my pocket to date, and on occasions was glad I put these in my pocket as an automatic daily routine. Yes, I would recommend getting these, the price is reasonable, and in a "pinch" lol, they work just fine. ... show more

  • I highly recommend these!
Color: Printed Flag Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 1.5 x
These are great for on-the-go! I hated caring my readers everywhere, in case I needed them. I was so afraid I was going to break them. Now I carry these Thin Optics every time I go out and I don't have to worry. They work great for short term use when you need them. Saving your readers for normal use at home. No more large case in your bag or pocket. I have mine attached to my car key. They go where I go. ... show more

  • Great portable readers
Color: Black Case / Black Frames Lens Width: 44.45 Millimeters Magnification Strength: 1.5 x
Love the fact that these can easily slip into a pant pocket and I barely know they are there. They work great and have saved me in the dark restaurant menu situations frequently. Not meant for long wear as they will either eventually slip off or will be uncomfortable (nose piece has a grit to keep on your face). This, for me isn't a problem as I only need them occasionally. ... show more
