Off to collect glasses

I wonder how much of a difference they'll make? I have slightly blurry vision when reading stuff off the whiteboard from the back of the class, and I find driving in the rain at night stressful, and occasionally subtitles on TVs that are distant are hard to read. Should be good for those sorts of occasions! I also wonder whether the occasional headaches I get (like the bastard headache I had yesterday that tried to make me do no writing) are eye-strain related, and will be lessened by glassesness. Off I go to find out!
