2dogs -- good one



As you probably know LED/LCD displays have a viewing angle and often polarization issues plus there is the matter of background/foreground differential. The GlowShift gauges are a White face with Red needle. Super easy to read in all riding conditions although tricky to photograph.
So let's examine my light path. LED/LCD is transmissive and must pass through my faceshield (Bell Panovision ProTint) then my sunglasses (kinda dark and probably polarized) and then my cataract lenses (monofocal with aspherical lenses to reduce glare) so things get dim. Meanwhile the GlowShift gauges are reflective and while subject to reflective glare they aren't to light path dimming.
In the early mornings and late evenings when I'm not wearing sunglasses I can read the Spyder's LCD dashboard without difficulty. But Hey this is California the LED/LCD-unfriendly Sunshine State so sunglasses are almost a full-time thing. GlowShift is my answer. Which is why I'm replacing the voltmeter with a clock.
WRT DMV eye exam, sitting in the second row of the El Cajon waiting area I can read the entire eye chart. My ophthalmologist is very pleased with his work and I even more so.
