Old eyes need the power of the sun

[John Hicks]

I've noticed that as I get more ancient; I require five million candle power to see well enough to do anything on the lathe. 10,000 lumens hanging right above the lathe just doesn't do it. Magnetic lamps,old chicken coop reflectors, sewing machine lights. Maybe I need some 4.00 magnifying glasses? Just a observation. Now I know why I've seen lathes that were outside.

My advice is never never take a turned piece outside. I have tested it thoroughly over the years....and I am absolutely convinced, without any doubt whatsoever, that sunlight causes sanding swirls.

Donovan, I believe you!

Sometimes a better quality of light is better than a larger quantity of light, If your eyes get any direct glare from a source of illumination your iris will close down requiring more light to be able to focus on an object. If you have multiple sources of direct points of illumination glare this can cause eye fatigue as they constantly refocus from intense light levels to lower light levels. As you age you end up needing about two to three times as much lighting as you did in your youth depending on the task being preformed.
