One thing to remember, for those of us who have to wear glasses, stronger,
brighter lights increase the focal focusing range, due to eyes irises opening
being smaller. This is why I prefer glasses with focal point matched to the
radio gear arranged in arch, at the same distance from the eyes. That gives
me sharp picture of all the important faces, screens and dials. Unimportant
stuff gets fuzzy and dont bother me :-)
Those days when I could operate by the warm glow of dials are gone.
