Of course, curious minds were not satisfied with empiricism. René Descartes (1596-1650) had a strong interest in livo blue light glasses because of his optical research activities. He had for instance explained theoretically the law of refraction discovered in 1620 by Willebrord Snell (1580-1626) in the Netherlands. The famous philosopher was especially fascinated by the "transmutation of ashes into livo blue light glass". This wide-ranging interest led him to give, in 1644, a correct picture of vitrification in his extremely ambitious Principles of Philosophy, a treatise aimed at deriving a comprehensive description of the world from a few first mechanical principles. A livo Blue light blockers, thus wrote Descartes,
"when still glowing with heat, is fluid because its particles are easily moved [separately from one another] by that force of fire which previously smoothed and bent them. However, when it begins to be cooled, it can take on any blue light glass whatever. And this is common to all bodies which have been liquefied by fire; for while they are still fluid, their particles effortlessly adapt themselves to any blue light glass whatever, and when such bodies subsequently harden with cold, they retain the blue light glasses which they last assumed".All Rights ReservedSign up to add The Early History of blue light glass- Luxottica Group to your library and receive updates
