cplh and colour vision defiency
Not a colour problem but wondered if contact lenses are acceptable. I ask purely out of interest as i am not a qualified pilot, more of a build your own and try it fellow. I have however noticed, (I wear contact lenses) , that as i climb a hill, or elevate by other means. My contact lenses either expand or contract and cause a few moments of slight discomfort and blurred vision. Hence the question. Bug.
