Well, a visit to an ophthalmologist is an option or even necessary requirement.
I'm not so good in long distance diagnosis as others. So let your eyes checked. Cataract?
My personal story in simple words: years ago I had to undergo an eye operation and got 2 new lenses. One eye is good for reading, the other for "far away" sight.
However, the difference in dioptries was not big. This works perfectly for me. Not for everyone, which will be confirmed by your "eye-doctor". Just think about it
