The first consideration in imaging cellular samples is whether you are using reflective light (i.e. only seeing the surface of the material like a telescope,light source above the sample) or transmitted light (i.e. a light source under the sample, this is much more common style for hobbyist microscopes). Assuming you have a hobbyist, transmitted light microscope, the main challenge in imaging cells is staining the cells to make it easier to see the details of the cell easily. The most common stains are eosin (stains nucleic acids purple) and hematoxylin (stains proteins red/pink). The H and E stain is the most commonly used stain used by pathologists to look at tissue samples. I would recommend looking at stains to use and techniques for staining as a first step in looking at your samples. Otherwise, there's no reason why you can't do this. Good luck!
personally I'd say contacts.. glasses can fall off unless you get a strap around the back of your head. Plus glasses tend to get Really fogged up in hockey because of the heat off your face and the cold environment.. You'll lose visibility pretty fast.
