My last pair of lenses cost me 300€.

Ah, see, that's what I was afraid of: Zenni is stupid cheap; the glasses I'm trying to replace were about $70. Granted, that was more years ago than glasses are supposed to go between prescriptions, but still, I was hoping for approximately an order of magnitude less cost for these DIY-cut lenses.

Hehe sorry, I'm addicted to that shape - not for the style, but because small, round glasses are the type of glasses that sit closest to your face, so you get a huge field of vision with small lenses, and you can rest your head on a pillow without breaking the temples. No other style of glasses gives you that.

I like the idea of pillow-compatible glasses, but I already have a bit of resemblance to Harry Pottery that I'm not exactly looking to enhance. I tend to go for rectangular lenses.
