The sunglasses industry is highly concentrated, competitive and getting bigger every day. Many established brands like Ray Ban have been around for many years and continue to grow and release new innovative products. Compared to 2010, the sunglasses industry experienced a 3.2% growth by September of 2011. Out of the $32 Billion dollar vision care industry sunglasses consists of over 10% of that price in 2010. However they experienced a steep decline in the years before that boom.
We can all see colors in two ways, the first method of seeing color is when an object can absorb all other frequencies, reflecting back to the eye only the light wave that we see as the color. The second method we perceive color is when an object can directly emit the waves in the frequency of the color.
In relation to sunglasses there are three types of lights involved; direct light, ambient light and reflective light. Each have a difference in the way we perceive the light. Direct light refers to light which travel straight from the source directly to the eyes. Ambient light is light which has bounced in a numerous amount of directions and because of how scattered it is the source can no longer be identified. The last type of light is reflected light, which is commonly seen in the form of a glare, when the light is bounced off of a reflective object and comes in contact with the yes.
The goal of Ray Ban sunglasses is to prevent as much light (both visible and invisible) from coming into contact with our eyes as possible. A quality pair of sunglasses can reduce a majority of both direct light as well as reflective light. Ultraviolet rays can fall under both of these categories.
One of the properties of light which can affect the eyes if the right sunglasses are not worn is polarization. Polarization refers to the light which has reflected off of a surface. When sunglasses are said to be polarized they work to eliminate this reflected light before it can do damage to the eyes.
With all of the recent advancements in the sunglasses industry, picking the right pair for you can be daunting. There is a wide variety of types and styles of sunglasses to choose from, without enough background knowledge you can end up with a pair that does not fit your eyewear needs.
Most people are aware of the basic purpose of sunglasses such as Ray Bans; to shield your eyes from harmful ultraviolet radiation as well as other hazardous lights. Short term effects of sun overexposure include a temporary vision impairment, while long term overexposure effects are more serious and can lead to cataracts and loss of night vision. In both cases, the damage is caused by ultraviolet light, which is actively burning the surface of the cornea and should be prevented. While this is an integral feature of sunglasses there are still many more features that should be considered before purchasing a new pair of sunglasses. With such a large array of selection to choose from it is important to know the different benefits and purposes of each type of sunglasses available. For example, different tints can help visibility in different conditions.
Both anti-reflective coatings and polarized lenses work to cut reflected light and in turn improve visibility on surfaces that light bounces off of (i.e. water). Many people who frequently are in the snow or participate in water-based activities use polarized lenses for this reason.
Sunglasses have been around for many years. They date back to ancient China and Rome, however in those times they were not worn to protect the wearer’s eyes. It has been said the Roman emperor Nero used to watch gladiator fights through polished gems for enjoyment. The first sunglasses were made out of lenses which were flat panes of smoky quartz. While they did not include the protection from ultra-violet light they do now, they did however reduce glare. Many Chinese judges used the glasses conceal their facial expression during interrogations.
It was not until the eighteenth century that James Ayscough began experimenting with tinted lenses in spectacles. Although these lenses were also not designed for protection from UV rays, it was his belief that through tinting these lenses a blue or greenish color they could potentially improve certain vision problems.
Yellow and brown-tinted spectacles were also a commonly prescribed product for people who were suffering from syphilis in the 19th century, because the disease caused an increased sensitivity to light.
By the early 1900s, the use of sunglasses became increasingly popular. Celebrities and movie stars began wearing sunglasses, mostly to because the arc lamps that were used for slow speed film stocks caused the eyes to turn red. And the Ray Ban Sunglasses were born.
The inexpensive mass produced sunglasses we all know today did not did not come about until 1929. When a man named Sam Foster brought them to America. Sam’s sunglasses were specifically designed to protect the wearer’s eyes from the harmful sunlight. His sunglasses were sold mostly on beaches in Atlantic City on the boardwalk.
Although many people use sunglasses as a fashion accessory they are actually much more than just another pair of Ray Bans. Sunglasses are a shield or protection for our eyes from harmful lights and radiation that could damage your eyes and the surrounding tissue. Overexposure to lights such as ultraviolet radiation can do lasting damage to your eyes as well as your health. UV rays are invisible so even if it is not sunny outside, you could still be at risk of overexposure. You can find the best criteria for choosing your next pay of Ray Ban Sunglasses after the break.
Sunglasses For Children
Most parents are aware of the potential damage the sun can do to their child’s skin, however they often neglect the amount of damage that can be done to their eyes. It is vital to your child’s health to not only where sunscreen but use sunglasses while outdoors. And besides, what child doesn’t look cool in a nice pair of Ray Bans? Sun damage is cumulative, so it is important for children to have adequate sun protection at an early age. The sooner you start protecting your child’s eyes from the sun the lower the risk of developing ocular problems down the line.
Making your children wear sunglasses can save their skin and eyes later in life, by shielding them from harmful ultraviolet radiation. Overexposure to the sun’s rays can cause significant issues and diseases in the future. It is also important to remember that UV rays are dangerous when it is not sunny outside as well. Because they are invisible rays of light, they can do significant damage even when it is cloudy outside.
By the age of ten, children are already at high risk for eye damage because of UV radiation. The skin surrounding their eyes is more susceptible and vulnerable to sun damage than the skin of an adult. Another contributing reason why children are at a higher risk of damage is that until the age of ten, the lens of a child’s eye is much clearer, which can allow for a greater level of solar penetration and ocular damage. It is not until later on in life that the eyes fully develop and add an increased level of protection. UV radiation is associated with several ocular diseases such as cataracts and macular degeneration, two disease that diminish visibility and eyesight.
Using high quality sunglasses can offer protection from the skin and the eyes from harmful UV rays. It is highly recommended that once a child is older than six months they wear sunglasses while outdoors.
Sunglasses, like Ray Bans, are a type of protective eyewear designed to prevent bright sunlight and high energy visible light from damaging or causing discomfort to the eyes. The sunglasses industry has made some incredible innovations over the last few years; new brands, styles, colors and functions have all surfaced recently.
Healthcare professionals and experts recommend eye protection whenever the sun comes out in order to shield the eyes from ultraviolet radiation and the blue light. The sun is very powerful and can have a detrimental and damaging ramifications on the cornea and retina of our eyes. Bright sunlight can be merely a distracting annoyance, however over exposure can cause soreness, headaches, or even permanent damage to the lens, retina, and cornea.
Short term effects of sun overexposure include a temporary vision impairment, while long term overexposure effects cataracts and loss of night vision. In both cases, the damage is caused by ultraviolet light, which is actively burning the surface of the cornea.
When considering purchasing sunglasses there are certain features you should be familiar with. For instance: sunglasses should provide optimal protection from the sun’s harmful rays. A high quality pair of sunglasses can protect you from any UV rays. Another consideration to take into account is the degree the glasses shield from strong lights. When a powerful light comes in contact with the eyes the iris closes and can cause squinting. eventually this extra light can cause significant damage to the retina. Effective sunglasses can eliminate up to 97% of light.
