Rainbow glasses are a type of eyewear that features lenses made with a rainbow-colored film. They are often seen as a fashion statement, but they can also be seen as a symbol of pride and acceptance for the LGBTQ+ community. Rainbow glasses first became popular in the 1970s, during the height of the Gay Liberation Movement. They were seen as a way to celebrate diversity and show support for the LGBTQ+ community.
