It depends on what type of person you are and your facial features as well as the glasses frames you choose. So, you shall try on to see if the clear fashion glasses flatter you. And choosing proper glasses frames can make you look more beautiful. Usually, for people who always have dark circle, puffy eyes or swollen eyes, wearing a pair of fashion glasses(you can wear non prescription glasses even if you are perfect vision) is a good way to flatter you.
I think clear fashion glasses are cool. Some types of glasses do make people look cool and fashionable. So people with perfect vision would go for the trend of wearing clean fashion glasses. I would admit some people do look more attractive with glasses on and there is no way that someone will know if you are wearing fake glasses or not.
