As blue LEDs are much brighter (at least perceptually), they need to be dimmed down a lot to be reasonable in many applications.
Unfortunately when the OMG-blue-LED fad first hit, many manufacturers apparently just treated them like other colors, and didn't modify their designs to account for the brightness difference, resulting in the searchlight-in-the-eye experience.
My perception is that things seem to have gotten a bit better since, with designs being modified to make blue LEDs less blinding, or manuf.s just switching back to more traditional colors....
