I use a set of glasses....bifocals with a larger bifocal set for the gauges...plays havoc on the medical...no reading something at 18cm's...have to stick my arms out to read....at which point the Quack squawks! The Bifocal sets a touch lower than normal...that allows me to see over the top of them when looking out and down onto the longline. Now if I could just bend over around the residue of 10,000 gallons of beer.....it would work a charm.
