Try adjusting the angle of the lenses with respect to each other, more -- instead of /\. A few that I got had a strong angle but were much better after I flattened them out. Of course it could be other things like getting astigmatism wrong but it's a quick thing to try out.
You don't need a tax. Just get rid of the massive subsidy that HFCS gets.
edit: I had meant the indirect subsidy through corn subsidies. I agree that there shouldn't be much of a distinction between HFCS and sugar (fructose) from other sources.
HFCS is equal parts fructose and glucose, exactly the same as sugar. Your link indicates no distinction.
HFCS is produced by running corn starch through an enzyme process identical to one that happens in your pancreas. Corn starch is broken up into glucose and then half the glucose is converted to fructose.
Personally I find HFCS drinks have a mild metalic aftertaste whereas sugar doesn't. I don't know what causes it. But HFCS is metabolically exactly the same as white sugar. And neither are "bad" for you.
It's the amount that matters. HFCS is cheaper to produce thanks to corn subsidies and cane sugar tariffs, therefore more of it goes into food, and it goes into more types of food. The tax I proposed above is a way to offset this effect.
Increase the frequency, yes. That's what I thought as well.
But then you run into other issues. The higher the frequency, the less "neat" are the up/down transitions, so your power elements (MOS-FET or whatever) spend more time in that twilight zone, which is exactly where they dissipate most power. And you want to avoid that.
Anyway, it's worth investigating along these lines.
My solution was to set the location to south of Hawaii. That gave me the best combination of bright during the day and not dark until 8pm or so. Setting my actual location was making it darken before 4pm.
It's not irrelevant. It's a design decision that punishes curiosity with unwanted and nonundoable actions. What else is the site going to do on my behalf because of something as simple as parking my mouse on the wrong part of the screen or in this case hovered over a nonintuitive button expecting some hover text to tell me what it is?
