I have myopia and wear vari-focal glasses. I am thinking of having the lens in one eye replaced so that I would have very good distance viewing in one eye, leaving the other - which is good for reading. Apparently this is called blended vision. I wonder whether anyone has had this done, and in particular whether it was good for playing sports? I still play tennis and cricket avidly.
Recommendations please, for a stopover on the way to Loch Tay
