Pass - I have glasses, but I don't have first hand experience with Monarch scopes (I got one from Austria).
It will depend on whether you are short-sighted or long-sighted (long-sighted glasses wearers need more eye relief), and on the fit of your glasses in relation to your face/eye.
The eye relief for the 30-60 WA eye piece is given as 14.2-15.2 mm.
The 20-60 eye piece has got an extra millimetre: 15.3-16.1 mm
I think you'll have to try and see for yourself. I suspect if you are short sighted it should be fine, but if you are long sighted it won't.
One of my binoculars have similarly short-ish eye relief: Canon 18x50, per manufacturer ER=15 mm, but the lens is somewhat recessed, so it is really less than 15mm. Works with my (short-sighted) glasses, but really just about, while other users have found these bins unusable with glasses.
Good luck
