I also prefer glass lenses. The tradeoffs seem to be weight (glass weighs more) and durability (glass can be cleaned with cloth or a towel without scratching, plastic lenses need to be babied with a microcloth or else you get little swirly scratches that will eventually ruin the lenses).

I'd rather have my glasses weigh a bit more if the lenses are more durable.

Don't clean your glasses, wash them.

The scratches are caused by particles of dust pressed by you against the lens, and then rubbed all around. A quick rinse removes almost all the dust, and then you can dry them with any clean towel, tissue or even the shirt. I also use a drop of soap to degrease them.

I have plastic lenses with zero scratches after five years of use.

Oh, I know about this. I did rinse them thoroughly. Then I used a few drops of Dawn dish detergent to wash them. But what I found was that even if you clean plastic lenses thoroughly, what counts is how you dry them. If you use paper or even a towel it can scratch them incrementally over time.

It's so much more convenient (or maybe I'm just lazy!) to be able to dry glass lenses with a towel, paper towel, a t-shirt, or anything absorbent.

The dish detergent seems to get under coatings and ruin them, in my experience. Glass cleaner is fine, though.

Yeah, scratching was the biggest reason I went back to glasses. Got a plastic one last year and within months it got plenty of scratches. Before that I had glass lenses that lasted more than 5 years (though one of lenses did break, which is why I wanted to try plastic).
