computers and the law of unintended consequences
In a previous post some trouble was noted with polarized sunglasses and some computer displays. Since I had planned a light "play around" ride for today I decided to undertake some research. It turns out that you don't need to ride to check this out but any excuse to go for a ride is a good excuse.
I have brand new clip on polorized sungalssis to go over the top of my regular glasses that are the self tinting "transitions" Somewhat overkill but they came free and I plan to use them in the fall and for right now when there are no leaves on the trees (sorry California Dwellers, I will attempt to send pictures to explain) and the sunlight/shadow bars when the sun is low in the sky are a pain.
Low and behold, 6 different computer displays are almost invisable from certain angles and have morie patterns and looked burnt from others. Polorized glasses off, gone, ok to read.
I went about trying to establixh a mounting angle that would work. My old trick of mounting the display on the bar with the front slightly down from horizontal appeared to help for some ie My Cateye Strada is ok with this method but my high end Cateye double wireless can't be read at all. Appairently the lens over all of these displays is already polorized and the interaction of the two polorized lenses is bad (didn't we all play this game in school). There is no way to know if the manufacturer is consistant with the lens so what works for one display may not work for another on the same type of computer.
I plan on using the polorized glasses as necessary and mr. computer will just have to go along for the ride on those days.
Can anyone test the Garmin 305 for this. I'm certainly not going to spend the money if I can't read it.
