Sunglasses are often worn as fashion accessories but they have other more important functions to serve.
- Protection for UV light for adults and kids
Ultra violet light is a useful substance but when humans are exposed to too much of it there are dire consequences. It is widely known that too much exposure of the skin to UV light can result in melanoma and skin cancer. At the lower extreme, a person can suffer some simple sunburn. The same applies to the eyes. The UV light can burn the cornea and cause some possible permanent damage. This is why people are advised to never look directly at the sun. Proper sunglasses that have been treated to offer 100% UV filtration are the best. They also reduce the amount of visible light that passes through the lens aiding those who suffer from light sensitivity. They however should not be used to look directly at the sun even during eclipses.
- Light Sensitivity
There are many suffers of light sensitivity. They are unable to properly see in bright places and at times have a physical reaction to too much light exposure such as migraines. Light sensitivity is a common symptom in many illnesses and makes it difficult for people to function in everyday life. Fortunately it is often a temporary condition. Sunglasses help suffers to cope better. They are able to perform daily tasks without having to squint or get headaches.
- Harsh Environment
There are people who work and live in places with harsh climates. They often wear protective gear and should never neglect their eyes. The eye is very delicate and will also suffer is exposed to harsh conditions. In places like deserts there are high temperatures, lots of wind and even more sand. There is also the large amount of direct sunlight without cover. Shades would be very much needed to protect one from the elements. For those who work and live in situations where they are exposed to the reflected glare of the sun’s rays, it becomes necessary to make daily use of sunglasses. This is common among aircraft pilots, sailors, fishermen and those who live in snowed areas like the arctic. The light reflected by the sun off the ground can completely obscure one’s vision and continued exposure can cause serious and permanent eye damage.
- Fashion Trend
As mentioned earlier, most people choose to wear Sunglasses (or solbriller asa we call them in Denmark) because they are fashion. Fortunately this can help draw the public’s attention to the need to not only cover their skin, but also their eyes from the sun’s harmful effects. There are many classic designs including the cat’s eyes and oversize design. If one is keeping up with the fashion trend that it might be useful to browse online and visit stores to see what is current. There are a large number of designs and colours to choose from, for both the lenses and the frames (or brillestel as we call them in Denmark). For those who wear shades as a necessity, such as for sport, there are limited designs that are however meant to be for functional use rather than decorative.
