I experience both of these. I have terrible balance - I can't kayak and climb anymore. I even have trouble in the shower. I fell off a bank of snow most recently. My eyesight is not the greatest. It seems to change as the day progresses - I'm told lamotrigine might be cause for this. In the mornings it is blurry. By midday I am seeing 20/20 but by dark I feel I'm not seeing as well as I should. I only drive if I absolutely must (maybe twice a month). Although the balance issue prevents me from doing things I love it is the troublesome eyesight that bothers me the most.
