I've discovered a couple of things that have been helpful to me. I
use two sources of illumination on my work piece; and I have no
idea why, but florescent light seems better (more illuminating) to
me than incandescent.
Yes, two sources of illumination has helped me a lot too. One light
fixture has both florescent and incandescent lamps and the other
light fixture is halogen. I can use one, two, or all three bulbs.
Often I use only florescent/halogen or incandescent/halogen (two
fixtures) and then switch to the other or add turn on the third lamp
when my eyes get a little tired or I sense eye strain. The “change
up” is like a cup of coffee for my aging eyes.
Curiously enough I was at my dentist yesterday who was waxing lyrical
over his new Carl Zeiss Eyemag binocular loupe which is apparently
the replacement for my increasingly dated Zeiss G3 loupe. Of more
interest was the Voroscope 20,000 lumen LED light source which
mounted on the eyeglass frame and is powered by a small belt attached
rechargable battery pack with a stated 14 hour battery life. The
mounting ensures that the light is directed at the point of view.
Although I only had a brief exposure to it and could’nt check it out
in a bench environment it certainly caught my attention as the light
weight and the belt attachment eliminated the “tether” problem
associated with the Zeiss 1500 cold light illumination system. Worth
checking out for those considering this type of visual aid.
Hratch, I’m not sure what it is I said that you’re responding to,
but… it sounds like the lighting that you describe from Orascoptic
is perfect for dentists who want intense light on a small area like
a mouth.
I use two inexpensive fluorescent lights, commonly called desk
lights. I like them because they’re portable so I can direct the
light to where it’s most effective. I direct the light to hit the
work at particular angles, to minimize reflection for example. This
is for me especially important when I work under the scope which
already has a ring light around the lens. As to why, I don’t know,
but fluorescent light is more illuminating for me. It may be a
personal oddity.
