You've never seen anything like these...
The coolest glasses you've ever seen! ThinOptics are compact glasses that are almost indestructible. They are lightweight and can be carried on a keychain. They are so small and compact; people would never suspect that they are glasses.

Best thing I’ve bought in years!
This is an awesome product!! I highly recommend it. It’s so convenient, compact and so far (fingers crossed) quite durable. I’ve had these key ring glasses for about 3 months now and I absolutely love them! Having said that, I think it’s pretty common sense to handle them with care. But even if I had to buy one every two or three months I just might! That ‘s how much of a game changer they are for me. Now what you should know is that they are not glasses for social occasions or any kind of rigorous or action based activity. So for example, you shouldn’t wear them while you’re cooking (unless to glance at a recipe) or eating. They will pop off your face once your expressions change, like when you laugh or smile because there’s nothing hooking it onto you face except for the clamps at the bridge of the nose. Also they work just as well as my regular reading glasses. They are very light weight and on occasion I’ve forgotten they were on my face because they are so light. The times they’ve worked best for me was when I was at the post office or grocery store or even the doctors office and needed to quickly fill out a form or read the packaging of a product or even read something leisurely while waiting for an appointment or even to glance at a menu in a restaurant. They’ve been absolutely Indispensable! I highly recommend this product & I stand behind the five stars I gave it!

It's pretty convenient, but not too comfortable
I recently acquired a keychain glasses, and I must say, it has its ups and downs. On the positive side, the glasses are incredibly lightweight, making them easy to carry around without any hassle. Their compact size is a real boon, fitting conveniently on my keychain, ensuring I always have them on hand when needed. Moreover, I was pleasantly surprised by the clarity of the lenses. Despite their tiny size, they provided a clear and sharp view, making reading a breeze. However, I did encounter a drawback: the glasses felt a bit too small for my nose. This made them a tad uncomfortable to wear for extended periods. Despite this, the overall portability and functionality of the keychain glasses are commendable, making them a useful accessory for quick reading needs on the go.

Good, not too bulky.
This is my second set of Thinoptics and I like them. Used to keep my former pair in a pocket in my phone - changed up phone case for a slimmer one that doesn’t accommodate. I didn’t want to attach a Thinoptics case to my phone via adhesive - I didn’t think it would stay so I decided to try the keychain case. even so, I was skeptical - I’m trying to keep the bulk factor of my house/car key set down. Totally prepared to send back if I wasn’t happy. Happy to report that it works for me. It doesn’t dominate my key set and lays flat in my pocket. Pay attention to how the glasses set in the case - don’t force it if it’s not in the ‘groove’.

So light you can't even feel them, doesn't pinch your nose if you don't put them on too tightly
Just got them a few minutes ago and am VERY IMPRESSED! They're very thin, and I can't even feel them on my nose, yet they seem to have a firm grip yet fit nicely. Initially I put them on a bit too tight but after I adjusted it, I can't even tell they're there other than I can see to type this review. I got them on sale plus $5 coupon so it was like $15 shipped which was a great value but I'd absolutely pay full-price for these now that I've given them a go. The 'key fob' case takes a bit of finesse to get used to, but I'm getting the hang of it. I'm in between 1.5 & 2.0 so they're a bit strong for me but my vision with them is leaps and bounds better than without them.

Great idea, not so great execution
Hands down, these are a great idea. I always have my keys when I'm out, so I'll always have my reading glasses. That by itself is the killer concept. They can be a bit finicky to work with--more in getting them back in place than in taking them out, but not really a headache. You have to get them into a friction-based clasp just right or they'll fall out. The main issue, however, is that despite putting them away religiously when not in use, the pair I bought became scratched beyond use after about a year and a half. I don't mean they started to scratch after that time but that they were so scratched up that I stopped using them. I'm not expecting high end material for the cost but they wore out faster than the drug-store reading glasses I've been using for years.

THESE ARE GREAT
These are great. DO NOT listen to the people who say they are impossible to get on or off, or in and out of the case without smudging the lenses. This is just not true. The key chain case works great and is easy to use. Glasses go in and out very easily. Keep these on your key chain and you will never be without again. And for those who say the fit is too "snug", these lasses are designed to come in handy when you need to read something quick like a menu or a label. They are not intended to be used to read War and Peace. Great find.

Super handy !
I bought as a gift for a friend that struggled to keep track of his reading glasses when he was out and about, these are so compact and easy to to keep in pant or shirt pocket! He laughed at first then then realised just how useful they are!

Great idea, never forget your specs
Love this keyfob idea - now I always have a set of specs with me. The glasses are easy to pop out and put back into the fob. They're held firmly and cannot fall out when using keys and don't get damaged if you drop your keys. Terribly handy if you keep forgetting to take your glasses with you.

ThinOPTICS Excelentes
Excelente producto. Muy práctico y fácil de usar. Es tal y como aparece en las imágenes. Me olvidé del problema de tener los lentes colgados al cuello para cuando se ofrezca leer en pequeño.

Very useful
I found it to be very useful on a daily basis. My current glasses are too bold and heavy to carry them around (lens to short range only). Now, I always carry with me the ThinOptics keychain and I use it everywhere, specially at lunch hour - very very handy to quick peak at my phone messages. Lens are adequate for use at short periods, the focus is very good (my experience), they seem very robust and are easy to clean. Because they are very lightweight they stay firm when "attached" to the nose. Perfect product, very well done. Great value for money, in my opinion ;) ----- Me pareció muy útil sobre una base diaria. Mis anteojos actuales son demasiado audaces y pesados para llevarlos (lentes a corto alcance solamente). Ahora, siempre llevo conmigo el llavero ThinOptics y lo uso en todas partes, especialmente a la hora del almuerzo, muy útil para alcanzar un pico rápido en mis mensajes telefónicos. Las lentes son adecuadas para usar en períodos cortos, el enfoque es muy bueno (mi experiencia), parecen muy robustas y fáciles de limpiar. Debido a que son muy livianas, permanecen firmes cuando están "unidas" a la nariz. Producto perfecto, muy bien hecho. Excelente relación calidad-precio, en mi opinión;)
