Yes, I am that age where reading spectacles are required.

I don't think it's a problem. I recall my first shave with a straight, (all nervous and terrified with full expectation of being cut to ribbons), and I think that if I can learn to shave with a straight, learning to shave with a straight (plus eye glasses) is a doddle.

I have actually started to shave without my eye glasses as I realised that after shaving my mug every day for about thirty odd years, I can actually do it by feel, and everything being a bit blurry is better than nothing.
