Why are Sunglasses So Popular?
Just as skin, eyes are vulnerable to damage from the sun’s ultraviolet light, which can lead to the development of a cataract. Sunglasses are an invaluable protective shield from ultraviolet radiation. For maximum eye protection, sunglasses must block at least 75% of infrared radiation. Professional sunglasses usually satisfy this requirement. To make this possible, various technologies are used: tinting, polarization, mirroring, anti-reflective or ultraviolet coating. Sunglasses with polarized lenses are generally used for water sports and driving, while mirror coated lenses are especially useful for snow skiing. Wrap-around sunglasses are ideal for cycling and activities in sandy or windy conditions.
But besides their protective function, sunglasses are a means of self-expression. They have been popular as a fashion accessory since the 1940s. Sunglasses, also termed as spectacles, goggles or glasses, are relatively affordable as compared to other fashion accessories, which is why practically everybody has at least one pair of sunglasses. Because of their moderate price, an individual can use different sunglasses to add a finishing stroke to well-planned attire.
Another reason why sunglasses are so popular is that one can always hide behind them. This is especially useful for celebrities and film actors who want to mask their identity.
It is important to choose the right pair of sunglasses. In general, the rule is to choose shades in a shape that is the opposite of the face shape. Round faces look best in angular, rectangular, or oval styles and wraps and shields. Soft, curvy styles reduce angles of square faces. Triangle faces look better in cat- eye shades, while almost any style works for oval face.
Sunglasses are available in a large range of styles and colors – aviators, wayfarers, teashades, Jackie O sunglasses with metal, plastic or nylon frames. It is easy to find a perfect pair of sunglasses for any social event, outdoor activity, and weather conditions.
