Bugger, isn't it a bitch to grow old?
Don't know, will let you know in a few years.
Re. bifocals, I had trouble getting use to them, so I went multifocals. This was ten years or more back, best specs ever. Sharp and crisp vison for reading, watching speedo and GPS, and better vision in medium and long range.
Shoulda gone to Specsavers, I get two pair multifocals (one pair clear lenses, the other tinted) for around $300, after private health insurance rebate around $100. I get new pairs every second year or so.
Re. cataracts, I had both eyes done, must be 15 years ago. Took a coupla weeks for cloudy vision to come good and night vision much better. Don't remember the cost, as I'm guessing the private health insurance took most of the sting out of the bill.
For what it's worth, when it comes to renewing your licence, there's a question about any medical conditions that effects your driving / riding. DON"T answer yes, unless your driving / riding is REALLY effected. A 78 yo mate of mine (a bit of a goody two shoes) answered YES, VicRoads took away his licence. I said, Graham, "You were driving okay just a coupla weeks back." (We were giving his Honda S2000 a real work-out in the twisties over Mount Hotham without a problem.) He said, "Yeah I shoulda shut up."
There's an appeal process, pretty arduous and expensive, and he wasn't successful. He's had to sell his motor home, XR6, XR6 & Turbo and Suzuki 4WD. Keeping the Honda S200, next trip over the hill will be my turn to drive.
And his wife is really happy about doing all of the driving.
