polarized sunglasses principle: fake cheap oakleys
polarized sunglasses principle:
Natural light (non-partial Aurora), in fact, will move towards a specific direction by the shock wave formed, which is reflected or scattered light and often prefer a particular direction, which is why polarized sunglasses can filter out the pool from the roof or reflection of the sun's sake; natural light filtering through the polarized lenses,<a href=" http://www.fakecheapoakleys.com//">fake cheap oakleys</a> you can make only one direction of light through, which means that polarized lenses can be polarized first light after only one direction of light through ( visible light) (Figure 1).
Polarized sunglasses is to use this feature to block harmful rays (Figure 2), because sunlight to touch any object, whether due to natural reflection or refraction will produce harmful glare, polarized sunglasses can completely absorb these will cause light glare and eye damage
◆ General sunglasses and polarized sunglasses for comparison:
Reduced use of sunglasses is generally the effect of light, because light can not be filtered lenses in general, we can only reduce glare, UV intensity, etc., and can not completely block these harmful rays (Figure 3-A), so its function is to reduce eye injury, but the biggest advantage of the general sunglasses is epidemic good. Polarized lenses due to a polarizing nature, it can be completely blocked due to scattering, inflection, reflection caused by various factors such as the glare. Also can the human eye completely block harmful ultraviolet light (Figure 3-B), makes long-term activities in bright light, tired eyes and easy to achieve real protection functions, and allows to see things more clearly,<a href=" http://www.fakecheapoakleys.com//">fake oakleys</a> three-dimensional (Figure 4).
◆ polarized sunglasses feature:
Life, there are too many light sources will produce harmful light, especially sunlight; the sun comes out too light are: visible light, infrared, ultraviolet, three (Figure 5). Them to ultraviolet light on human skin, eyes, etc. .., causing serious injury; released by the sun light in the IR (Infra-red) infrared (750mm) above, visible light (Visible light lay) (310 ~ 780nm) ; UV is divided into UVA, UVB, UVC (310nm) above, glaucoma (Blue light) which UVA, UVB, UVC light is harmful if prolonged exposure can cause physical damage, UVB is a serious visual impact, ( Tanning Ray) is burning black light skin, most eyes will absorb UVB light, so this must be out of this denial of light. Polarized sunglasses as a function of the light polarization, so that all can block out the harmful rays are not affected by visible light, can really function to protect the eyes.
◆ the application of polarized sunglasses:
Polarized sunglasses because it can block 100% of harmful rays, so the can be applied to:
1 Medical: eye surgery, you need a full range of protection, polarized sunglasses are the best choice.
(2) outdoor activities: such as skiing, fishing, water sports, etc., need to completely block the harmful rays of the sun glasses to avoid eye injury or fatigue.
3. Goggles
◆ types of polarized sunglasses:
So how to choose the polarized sunglasses do? The polarized sunglasses in different colors, each with different characteristics. Pink or red of the lens, the glare of a very strong case, can enhance the contrast and sharpness, ideal for water sports and snow activities to use. Brown or brown of the lens, because it can enhance the contrast of colors, so become the first choice for driving the lens. Amber, yellow or orange of the lens, is very suitable for wear when it is cloudy, the view can have a very clear, but it is not suitable for use under the sun. Gray or dark green lenses, depending on the material can retain the original color of nature, is a good choice.
Sunglasses are not only required to wear in the summer before,<a href=" http://www.fakecheapoakleys.com//">cheap oaleys</a> in fact, must be used throughout the year. To wear sunny, cloudy have to wear. Do not think that a cloudy day the sun is not strong, the weather is not hot, to be taken lightly, unconsciously but more harmful ultraviolet radiation. So even if thin cloud of cloudy, still have to refer to the UV Index forecast, a good sunscreen preparations.
