Why you should keep your previous pair of glasses....

So that when a nose pad breaks off your expensive frames, you've got a pair for 'back-up' to get you by until these 'cutting-edge, state-of-the-art, does everything but hold together' $760+ ones are once more repaired. And yes, Kiddies, I did say 'once more'. A lens has fallen out not once, but twice, and the magical coating on both lenses had to be replaced because my normal cleaning with a soft linen tea towel evidently was too harsh for it.

Why did a lens fall out twice? Look at the lower edge of the lenses. See that little groove there? Well in that little groove is a short length of filament, very similar to monofilament fishing line. That's what holds the lens up tightly into those sexy-looking half-frames of metal. Problem is, there's a tricky little cinch fitting which it has to be pulled tightly through in order to make it hold, and this has a couple of tiny little holes for this 'fishing line' to pass through, and those seem to sometimes cut into the filament, breaking it eventually, and suddenly you've got monovision instead of stereo. Or one eye seeing much better than the other - for $760+...... And here's the 'kicker' Folks - my older ones (that I'm now wearing again!) have the same system for holding in their lenses, and they've never had a problem! A fool and his money are soon parted. I have proof!
