those of us residing in northern hemisphere are currently subject to reduced daylight
around 300 years ago european watchmakers used clear vitreous globes-patterned after florence flasks--introduced into italian fermented spirits distilling in 1744-- and filled with clear fluid
the globes were positioned on the artisans table--during daylight hours sun
would pass thru forming a cone-like beam
during darkness-candle power provided a similar effect
an interesting variation is the quadruple french focusing lamp with
wooden adjusting threads
one thing is certain both in those times as well as now--aging eyes must have more light in order to perform precision tasks
