I ordered a set of prescription lenses made of Trivex and mounted them this morning. Those things are light, that ain't no joke! The video shows the weight difference with the same lenses mounted in the same frames but made of regular CR-39 ordered from a no-name supplier (the Trivex lenses came from Hoya).

I've worn the Trivex lenses for a whole day and the weight saving does make a difference in comfort. If you're into ultralight glasses, I highly recommend Trivex lenses. They aren't the cheapest lenses but I find them well worth the premium.

Now, if only I could get those glasses into single-digit grams territory... I'm so close 🙂
