Paul I am around your age range and had laser treatment 5 weeks ago, after wearing gas/hard contact lenses for 30 years. I opted for mono vision and have to say that I am delighted with the results. My left eye is the dominant one and is used for distance, while the right allows me to read perfectly. I have previously worn varifocals and guess this made the transition easier for me. Clearly it is down to what you feel comfortable with. For me it was most definitely the right choice.
