You've been told your whole life that sunglasses are crucial. You know that they protect your eyes, block out the sun's ray and prolong good vision. But have you ever wondered how these miracle shades do all of that? Of course not, but you must learn. Sunglasses basically do four things for you, apart from completing a killer outfit. It is important to grasp what these things are and how they are done to ensure your sunglasses are doing their job.
As you most likely understand already sunglasses provide protection against ultraviolet rays in sunlight. UV rays may cause significant damage to the corneas, and a good pair will shield 100% of these rays. A protecting coating on the outside of sunglasses acts as a kind of filter. While it allows light thru, it helps to clear out the radioactive light waves that can cause so many perils to your eyes.
Presumably the most commonplace purpose sunglasses serve is to provide protection from intense light. Intense sunlight can lead you to squint, a natural reaction to too much light entering the eyes. If squinting doesn't provide enough protection, damage to the cornea can happen next. This is especially common when outside in the snow without your sunglasses. The white of the snow reflects and magnifies the strength of the light.
The tinting of your sunglasses will help establish the quantity of light your eyes will be exposed to. As there are different kinds of light, all the colours of the rainbow, different shades of lenses will protect in their own ways. Grey and almost black coloured lenses will be offering the greatest quantity of protection against intense lights while being careful to avoid distortion of most colors that you see.
Another quality sunglasses carry is a thing we are all most likely grateful for. They can offer defence against glare. Water and other glossy looking surfaces can produce a glare. These glares can block out other objects, like a car turning out of a carpark just ahead of you. Good sunglasses can fully eliminate this type of glare using polarization.
Light waves vibrate just like sound waves do. When a grouping of light waves come together but are traveling in different directions, a glare occurs. When you are blinded by a glare off of the water or another vehicle's windshield, what you are seeing is a traffic jam of light waves. Polarization filters built into sunglasses are made from molecules that realign the light waves with each other and eliminate the glare.
As noted before, Sunglasses can eliminate specific frequencies of light. Certain light frequencies may cause blurred vision, while other frequencies boost contrast between colours. Selecting the best color for your sunglasses allows them to work better in specific situations.
Yellow, gold, amber and brown colored sunglasses are particularly good for blocking out blue light. Blue light is the color of light in the range that scatters and causes blurred perception. While the yellow shades can make the rest of the world look a different color, you will see most obviously and detailed through them.
Green coloured sunglasses are better for filtering some blue light and reducing the incidence of glares. They also offer the highest contrast and greatest visual sharpness of another coloured lens. For that reason, green sunglasses are popular. Rose coloured shades and purple tints offer the best contrast of objects against a green or blue background and make great sunglasses for hunting or water skiing.
Now that you know how sunglasses (Spanish: gafas de sol baratas) work you can be a responsible consumer. Know what to search for when selecting your sunglasses. It isn't a very bad idea to have more than one pair around for several different reasons. This is especially true if you spend some considerable time outside on a range of activities. Be responsible about your eyes and learn to defend your vision while it's still yours to protect!
