Monovision in glasses

Question

I'm 50, astigmatic, and normally wear glasses (a pair for near vision and a "driving" pair for long-distance). I occasionally wear contact lenses. At my last contact lens test, I commented to my optician that it was becoming frustrating going out in my lenses - they were fine for distant-to-far objects, but I struggled to read anything closer (eg my phone); and unlike my glasses, I couldn't just lift them up or peer over them.

She suggested a left lens for reading and a right lens for distance, and it works surprisingly well - although I can't keep them in all day, and only use them for going out. I wondered if a similar "different lens for each eye" approach could be adopted for glasses, rather than varifocals which I think would annoy me even more?

My current prescription(s) for the new contact lenses are:

left eye (reading) -1.5 - 1.50 x180
right eye (distance) -3.00 -1.50 x180

As you say, monovision in contact lenses can work surprisingly well. Unfortunately in glasses the problem is that as soon as you look through the lenses away from the optical centres a prism effect is produced and because there will be a large difference between the two eyes, you will have double vision. The best option is varifocals (or bifocals) but you do have to persevere and adapt.
