Do you prefer to wear your glasses while using telescopes & binoculars? I usually take mine off, if I can (I usually need them to see the sky and figure out my aim). I was wondering, though, whether I'd get more it if I kept my glasses on.

If I'm sharing with others, I keep my glasses on so that there isn't quite so much adjusting the focus involved for me and for the person who's using the equipment after me.

If I've mostly got it to myself or I'm going to be in the driver's seat for a long time, I take the glasses off because it's more comfortable and my prescription is high enough to produce a noticeable chromatic aberration.

I wear contacts...focus is different for each eye

People with astigmatism will need to wear their corrective lenses.

Those like me that are near sighted can either wear them or not. Like Nauthiz, I wear glasses at public events so that my telescope is already focused reasonably close to most people's vision.

With glasses, you want eyepieces that have decent eye relief. Preferably 20mm.

I tend to get vignetting with the glasses on, even with eye cups folded down.
