While clear glasses are rarely worn without the practical purpose of correcting eyesight or protecting the eyes, sunglasses have become popular for several other reasons and are sometimes worn indoors or even at night.
Sunglasses can be worn to hide the eyes. They can make eye contact impossible, which can be intimidating for those who don’t wear sunglasses; Avoided eye contact may also indicate disconnection of the wearer, which is considered desirable in some environments. Eye contact can be avoided more effectively by using mirrored sunglasses. Sunglasses can also be used to hide emotions; This can range from blinking to crying and the resulting red eyes. In any case, hiding one’s eyes has implications for non-verbal communication; This is useful for poker, and many professional poker players wear multicolored glasses indoors while playing, making it more difficult for opponents to read narratives involving eye movement and thus gain an advantage.
Fashion trends can be another reason to wear sunglasses, especially designer sunglasses from high-end fashion brands. Sunglasses of certain shapes can be in fashion as a fashion accessory. The importance of sunglasses in the fashion industry includes fashion shows that include sunglasses as a primary or secondary component of a look, as well as leading fashion editors reviewing annual trends in sunglasses. Fashion trends can also be based on the “cool” image of sunglasses and the close relationship between a particular lifestyle, especially sunglasses and beach life. In some cases, this link serves as the core concept behind an entire brand.
People can also wear sunglasses to hide the abnormal appearance of their eyes. This may apply to people with severe vision impairment, such as blind people who can wear sunglasses to avoid disturbing others. The assumption is that it may be more comfortable for another person not to see hidden eyes than to see abnormal eyes or eyes looking in the wrong direction. People can also wear sunglasses to conceal dilated or narrowed pupils, bloody eyes due to drug use, chronic dark circles or crow’s feet, recent physical abuse, exophthalmos, cataracts, or uncontrollably shaken eyes.
