I too wear Varifocals and have done so for years. Woulnt look back. In the early years the CAA were not too happy about them because they can impair side vision. However, they have had a change of mind and now accept them.
Soemeone mentioned having to carry a spare pair of glasses. Not always so. Only if the Medical Cert is so stamped, and, depending on the strength of your prescription this is not always the case!
