Hi Alan,
I've never worn anything else but a 3/4. Never had any problems. Goes on o.k. with glasses on. Only thing I've found (this helmet is 4 years old) is that the lining has worn through where the glasses arms rub - but no problem as such, & I suppose it could happen with any type of helmet.
The helmet I've got is an Aeroh, & the visor slides up under the peak to protect it. This is a nice touch, but sometimes the wind gets under the peak at highway speed, & I've got to really concentrate on stopping it pushing my head back.
