Wearing glasses for me is a relatively recent phenomenon (yep, getting old). Now that I have a DSLR and I want to use the viewfinder rather than the LCD display as much as possible, I’m confused as to whether to keep my glasses on or take them off when composing the image. I find myself doing both, sometimes with and sometimes without, and I’m convinced it’s affecting the quality of my shots (even though it might not be). My camera has a diopter adjustment and as I understand the user guide, it shouldn’t really matter if I take the picture with my glasses or not (especially if I’m using the auto-focus feature). I’ve searched the Web for tips and have found mixed messages. So I’m wondering, if you wear glasses or contacts, what do you do? Thanks.
