Here’s a fact- over $2.5 million was spent in USA alone to purchase 270 million sunglasses. You might be a traffic cop, a student, a banker, or a biker, but those cool shades have become a part of you. Often times, sunglasses are bought because they look ‘cool’. With brands like Bausch & Lomb, Vuarnet, Oakley, Killy, Hobie, Serengeti and many more, offering sunglasses in all shapes, sizes, colors and designs… who can blame you? The trend has caught on and it looks like it is here to stay.
In all seriousness, sunglasses should be bought with the aim of protecting your eyes from ultraviolet (UV) radiation. When sunlight that is reflected of snow or sand hits your eyes you could get a case of ‘snow blindness’. In worse case scenarios, ultraviolet radiation can cause permanent retina damage and cataracts. UV rays can affect you even when you are not standing in broad daylight. These rays can come through even on a cloudy day. People who have a history of cataracts and retinal dystrophies should be extra careful to use suitable sunglasses.
Different people buy different sunglasses depending on their occupation, style, gender and general fancy. For example, people involved in high-impact sports may opt for the Polycarbonate lens, which does not shatter easily. Polarized sunglasses are chosen for those who love water sports because it takes care of the glare factor. Mirrored glasses are also a hot favorite for people skiing the slopes or swimming.
