ThinOptics Flashcard Case with Rectangular Reading Glasses - Slim & Portable Eyewear Holder for Students, Professionals & Travel - Perfect for Studying, Office Work & On-the-Go Use

I bought these as contingency for my $200 varifocals, and as a more portable set of specs compared to full sized glasses. In the past, I bought a spare pair, or took advantage of of 2 for 1, but I eventually lost all the spares.These glasses are amazing. They stick comfortably to your nose, even with a bit of head shake. If you use varifocals, you will be used to moving your head/eyes to focus on near or distant objects, and if you do the same with these, you'll notice little difference in your vision. For example, I am now typing this on my laptop, whilst glancing at the TV a few metres away and it seems quite natural.They seem a little flimsy, but so do space age titanium wire frame glasses, and I would not wear them for an extended period. But they're perfect for taking with you on a sunny day when you're in your shorts, wearing sunglasses and don't want to look "excited" by the bulge of regular spectacles in your pocket.You may be worried about if these stick to your nose. But they will. They have an ingenious flexible grip which also acts as a shock absorber, so you have to make extreme movements for them to fall off.I wish I had learned about these years ago...
