It's possible for pilots to get a class 2 (PPL) medical with poor vision in one eye. I've attached some guidelines. Currently you wouldn't be able to fly commercially in the UK.

Medical is £180 so it maybe worth it for a clear answer, also I've been looking at BMAA microlights...... I'm really tempted
but in the UK its not going to be as toasty as a PPL....... Plus I'd like a roof
