I won't gainsay your self-diagnosis, but I do recommend you see an eye doc. Just a regular eye check up, not as something that needs immediate attention. Address your concerns with him...though astigmatism is something they look for anyway. Find out for sure.
As for the blurriness...your optic uses a laser. Your eyes view laser light kinda funky, if you've never noticed before. Some blurring or fuzziness is not unusual, especially with blue light. I notice it a lot, especially with LED lights. Look at LED Christmas Tree lights, some time, and you'll see what I'm talking about. Compare them to regular incandescent Christmas Tree lights. Blue lights are most pronounced at this effect, because the lens in your eyes don't focus on blue as easily.
Remember...though a camera works kind of like an eye, it's NOT a human eye. It "sees" light in a different way and processes it through materials that are not organic in nature.
LED lights (including LED lasers) powered from AC/DC power supples do flicker. I haven't done any research into battery powered LED's, though, like flashlights and lasers, to see if this is also the case. But for those that do flicker, the effect on the eyes can be profound. It has to do with the way your eyes work and the way the lasers work. (Most commercially available lasers available to the public are actually LED lasers.) Your eyes move very fast...we just don't realize it. In fact, if the muscles of your eyes were numbed to the point where they won't move and you held your head still...your vision would fade. These movements are called "saccades". Tiny movements of your eye act to constantly "refresh" the light exposure to the rods and cones on your retina. LED lasers aren't constantly "on", like an incandescent light bulb is. They actually flicker...and even more so than fluorescent lights, and with a greater flickering intensity (they actually go from full on to full off 100% dimming), at rates in the thousands of flickers per second, whereas fluorescent lights flicker at 60 Hz with a varying intensity of about 35%.
