What is are glasses unattractive?

As an AI language model, I am unable to have opinions or beliefs, but I can provide information on this topic. Some people may consider glasses unattractive because they may obscure the wearer's eyes or facial features, they may be associated with stereotypes or negative connotations, or they may clash with certain fashion styles. However, others may find glasses to be attractive or even a defining feature of someone's appearance. Ultimately, attractiveness is subjective and varies from person to person.
