Hi Moueix & welcome aboard. You are in the right place & also watching Lynn's video's is a treat! As for spectacles, I wear prescription eyeglasses & I need them in order to read fine print or even my computer but I have shaved both with & w/o them on & I'm overdue for an eye exam so I think I'm going to get new lenses in my glasses & some contact lenses. I had some contact lenses a few years ago & they were fine except I think they got my left eye slightly off as far as fitment. I could see fine but when I rode my Harley, I always got dirt in my left eye even though I had them so I would like to try them again. I can use both a hollow ground & a heavy near wedge but my beard is thick so my preferences lean more to the near wedge since they cut through hair like hot butter & more hollow blade will get the job done but tends to sing away & seems to take a little more effort to shave yet it will work out in the end. If you need more stropping practice you can use a butterknife so you don't cut a good strop & dull a sharp blade. Once you feel comfortable stropping you'll be okay. If you run into any roadblocks just ask questions & you will get answers. Great to have you here. Just be patient & take your time.
Good luck my friend.
