Ignore the die, that’s just to tilt the glasses up to more easily see the nose bridge. The rigup totally works, except that over time sweat degrades the heatshrink and it starts to swell. When the rigup was fresh, it was so streamlined that it almost looked factory made, but alas heatshrink doesn’t like sweat and body oils.
The exact model is apparently M•Flex ME507. The frames would otherwise be really nice, if it wasn’t for the fact that this is the second same set of frames I’ve had break in exactly the same way.
Impressive. Since you have the lenses and know the exact frame, maybe try buying another frame on ebay or similar?
Sounds good on paper, but isn’t worth it. Those lenses have really crappy scratch resistant coating that’s gotten eat up and really foggy from sweat, random chemicals, and general daily use.
Oddly enough, a friend of mine donated me an old pair of bifocals of his that were manufactured in 1988, and those lenses just so happen to match my eyes better than my last prescription, plus they have practically no scratches.
I lucked out on that, not often you run across a friend with vision so close to your own, that also happened to have an old pair of glasses he was willing to donate.
I’m not fond of the style, really big and thick bifocal lenses, but hell I can actually see the stars in the night sky with them! I can’t even say that much about my last official prescription.
foggy from sweat, random chemicals
Sweat shouldn’t attack plastic lenses. But one particular random chemical often does: acetone. It can strip coatings and turn tenses hazy. Did you use acetone by any chance?
I often use acetone to chemically-polish PLA parts. Whenever I do, I crack out the safety glasses. At the price I paid my lenses, I don’t want to risk a splash - or possibly acetone fumes even - damaging them.
Trust me, sweat totally attacks the coating. The worst spots for me are always where my glasses tend to rub against my eyebrows.
Could be simple abrasion.
But yeah, lenses aren’t eternal. You can make them last longer but they’ll age and wear out ultimately. Entropy is a bitch 🙂
