Hello Moueix, welcome to the club. Best advice I can give is take your time don't rush you will thank yourself later. Also don't be afraid to finish with another razor you are comfy with. I tried like hell to go 2 to 3 passes every time when my straight arrived and the razor burn was horrid! Also take your time learning to make lather. At first my lather would dry up before even getting to that part of my face, in turn I learned to only lather what was going to be shaved now I don't usually have that issue. I am in no way a pro but I get the best shaves I have ever had up to this point and only see them getting better. I can not chime in on your specs issue because I can still see well enough without mine to shave but I imagine someone will have help for you. I have the same razor you have purchased and I think you will love it. These fellas are more than happy to help and answer questions so ask away. Oh and best of luck!
