Glasses and contact lenses

Glasses: since the year 1300. At its introduction you can imagine every average person thinking, "glasses, no way, we don't know all the negative side-effects yet….let's wait for those to become apparent."

Contact lenses: Since 1960.

Just like glasses, contact lenses were not immediately accepted, although now they are considered very normal. Nobody questions possible side effects or dangers associated with the wearing of glasses or lenses.
