Okay, I recently got into photography because I've always loved the look of film photography and one day came across a Pentax K1000 at a thrift shop and decided to give it a shot. I haven't been at it for very long and have only shot one roll of film...I've picked up another camera since then and I just got a bunch of film so I can really try to jump into it.

My problem is...What's holding me back...Is that I get this weird foggy head feeling and my left eye gets blurry no matter how long I use my cameras...Even if it's only for a minute. I've started keeping both eyes open to at least prevent the eye problems, but I'm still getting these head feelings. It doesn't really feel like a strained feeling and I wouldn't call it a headache...More like a foggy, fatigued feeling. Does anybody know what I'm talking about? Is there any way to prevent this?
