サングラスを発明したのは誰
James Ayscough began experimenting with tinted lenses in spectacles in the mid-18th century, around 1752. These were not "sunglasses" as that term is now used; Ayscough believed that blue- or green-tinted glass could correct for specific vision impairments. Protection from the Sun's rays was not a concern for him. One of the earliest surviving depictions of a person wearing sunglasses is of the scientist Antoine Lavoisier in 1772. Yellow/amber and brown-tinted spectacles were also a commonly prescribed item for people with syphilis in the 19th and early 20th centuries because sensitivity to light was one of the symptoms of the disease.
