Continue on with your life like nothing happened. Don't let your vision keep you from living. I would recommend making some changes to diet, and avoid drugs and alcohol. Alcohol isn't as bad, but the day after, your visual snow will be more severe, until it settles back. I'd recommend getting plenty of sleep, as being sleep deprived makes my visual snow much more noticeable. I believe my visual snow was cause by my anxiety, as at the time, I was going through a very anxiety ridden phase in my life. Your best bet is to try and ignore it to the best of your ability, and your body will do its best to habituate.
