A problem solved. These polarised bifocal sunglasses are the perfect solution for outdoor enthusiasts. It’s a nuisance having to swap glasses just to check the chart plotter or make a quick log entry, getting half blinded by the sunlight at the same time. Now your glasses can remain in place while you keep an eye on the ships progress.

As the dark tinting of the sunglasses will make reading naturally more difficult you might find the 2.5 magnification a better choice even if your normal reading glasses are weaker.
