Choose the Fake Oakleys Frogskins Sunglasses Cheap for Sale lens with your degree, IPD and other precision data is closely related to the right of the lens allows you to see more clearly and more comfortable.

There are two kinds of resin lenses and glass. Glass, high hardness, quality heavy friable; translucent resin sheet is strong, lightweight unbreakable, protects against ultraviolet rays, but poor wear resistance. Highly refractive errors should use a resin sheet to reduce the weight of the lens; Children should not wear glass, because of the fragile and dangerous high. The thickness and refractive index of the lens depends on the degree of myopia lenses surrounding the central thin thickness, contrary hyperopia. The higher the degree of the thicker lens, the thinner the higher the refractive index of the lens. High refractive errors were the best choice for high refractive index Fake Oakleys Gascan Sunglasses Cheap for Sale lens.

Optical lens parameters and the relationship:
(1) IPD: eyes straight ahead or visual axis distance between the center of the pupil when two parallel!
(2) the refractive index of the lens: refers to the ratio of the lens through the air and speed when passing through the lens material. The larger the value, the smaller the lens thinner thicker. 1.5 Department 1.6 series, 1.67 series, 1.74 series four main categories.
(3) Coating Technology: the lens surface coated with a metal film are many trace element, increasing the light transmittance of the lens (94 ~ 99%) to see more clearly things complete. While special anti-fog coatings as well as radiation function. Common are green film, blue film, purple membrane, gold film, red film. Red purple blue film film which is basically anti-radiation film lens category, blue best. The most formal is green film, basically using this brand lenses, lens also has good anti-radiation function, and the lens than white, natural beauty of its films.
(4) spherical / aspherical: spherical lens to see things bend; aspherical Tiffany and Co Charm Bracelet Jewelry Outlet lens looks laps benefit is less, the eye will not be significantly reduced concave, and the other will not have to see things clearly bent.

Terms of optical lenses

UV

The word comes from ultraviolet, Fake Oakleys Frogskins Sunglasses Cheap for Sale commonly referred to as ultraviolet light, prolonged exposure would infringe the human cornea and retina. Ultraviolet light with a wavelength between 200nm ~ 380nm in the sun light.

Comprise three: UVA wavelength of 315nm ~ 380nm, UVB wavelength of 280nm ~ 315nm, UVC wavelength of 200nm ~ 280nm. Reach the Earth's surface in the ultraviolet UVA accounts for 97%, UVB accounts for 3%, UVC close to zero (the majority being absorbed by the atmosphere). UV damage to the human eye depends mainly on the wavelength, the irradiation time and intensity of ultraviolet radiation.

POLARIZED

Sense of the word is polarizing. The principle is the use of Cheap Ray Bans Wayfarer Sunglasses Outlet Sale polarized light, effectively filter out the glare of stray light, glare, reflected light and harmful UV rays, so that the light passes through the field of view in one direction parallel to the eye can be kept comfortable.
Lens choice

Different seasons different options:

Summer should choose a lower transmission rate of film color, such as gray film, brown film and coated tablets; sunshine weaker spring and winter, you should choose a higher transmission rate of film color, such as orange slices, white tablets.

Different sports environment different Cheap Mac Cosmetics Makeup wholesale Outlet options:

The beach, fishing, mountain climbing, etc. should choose dark film or coating films such as; riding, jogging select orange slices, light gray and light brown tablets tablets.

Space-chip technology

A widely used in aerospace equipment, advanced materials. Light weight, 37% lighter than glass, thin 26%, greatly reducing the load on the nose: impact resistant, not broken do not crack, its impact resistance is 10 times the normal resin sheet, and Tiffany and Co Key Necklace Jewelry Outlet take care of your eyes from foreign objects damage.

Through evaluation, overall it is a good spectacle, I found Fake Oakleys Gascan Sunglasses Cheap for Sale spectacle has the following characteristics:

Has the advantages:

(1) Frame with easy installation and removal of myopia box. Meet the needs of riders myopia;

(2) Frame designed to meet the person's face design, wearing them sticking good results, but also very comfortable. ;

(3) lanyard nice design - can effectively prevent loss during strenuous exercise outdoors, even when not wearing glasses hung around the neck so that is not easy to lose.

(4) Lens sharpness is good, the effect of polarized lenses is quite obvious, with outdoor color Tiffany and Co Charm Bracelet Jewelry Outlet lenses can quickly send the intensity of light changes.

Shortcomings:
(1) glasses case zipper rough work, short-term use and causing the zipper handle fracture;

(2) three pieces of lens still seems a little less, we ride in order to ensure the safety and enhance the brightness of a pair of lenses is particularly important in low light, when;

(3) rubber nose pad design is still a problem, try just once, it was found lost on a rubber nose pads pad;

I sincerely wish the manufacturers will be able to further improve by the presence of some of the shortcomings of the product for the majority of riders designed to create more and better Fake Oakleys Frogskins Sunglasses Cheap for Sale riding glasses!

For those who love cycling faithful car is able to have a better riding Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glasses is particularly important, because riding glasses can greatly protect your eyes during the ride will not hurt. This is very fortunate to have the opportunity to participate in the evaluation of this riding glasses SY-100, very happy to be here to share with you.

1 Remove one lens;
2 small purple light close to the Cheap Mac Cosmetics Makeup wholesale Outlet lens;
3 Shortly after, a place close to light source appear black specks, indicating lens color has changed.

Comes around 15:00, this season is still relatively strong light, wear glasses do not feel this sense of sun glare.

In this high-intensity off-road, the glasses do not slip loose phenomenon, indicating that the effect of this spectacle patching is good.

Zipper glasses case rough work, short-term use has caused a zipper handle fracture;

Rubber nose pad design, I think there are still problems, try them only once, it was found lost on a rubber nose pads cushion recommended way to design a fixed non-removable or fixed with screws design. This Tiffany and Co Key Necklace Jewelry Outlet design is easy to disassemble components will inevitably result in the same loss situations.

Polarizer is manufactured according to the principle of polarization of light. Also known as the Tiffany and Co Charm Bracelet Jewelry Outlet polarizer, is the use of polarization features to polarized lenses to non-metallic objects, such as water filters eliminate reflective lens. Reflective polarizer can be eliminated and make the colors more vivid, and even some movies shot the entire film with a polarizer to make the picture more gaudy colors. When the sun projected on the road or water, direct irritation of the eyes, the eyes dazzle, fatigue, vision can not be sustained. Especially when you drive a car, outdoor recreational activities, not only affects our emotions work and play, and even affect our sense of the images and danger; long withstand direct sunlight, but also lead to the rapid decline in vision, form of myopia, hyperopia, astigmatism or cataracts.

Can clearly be seen by comparing the Fake Oakleys Frogskins Sunglasses Cheap for Sale polarized lenses when not in use can only see one person after using polarized lenses can clearly see this man caught a big fish.

Color glasses principles

The mystery of the lens in color glasses. In the lens manufacturing process, the UV-sensitive pre-braced substances - silver halide, and a small amount of copper oxide catalyst. Glasses from no color becomes light gray, dark brown, black glasses and then changed back from ordinary glasses, silver halide changes are "magic." In the mirror of the lens material, there is the photosensitive film exposure imaging process very similar changes. The silver halide to light decompose into many black silver particles uniformly distributed in the lens, the lens so dim, blocking passage of light, which is darker. However, the situation is different, and photographic film is the decomposition of silver halide and halogen atoms, still tightly put together. When back a little darker place, in the role of copper oxide catalyst, silver and halogen compounds re-produce silver halide, lenses again become transparent. Lenses discoloration speed and depth extent of UV intensity and ambient temperature. UV discoloration stronger faster, whereas the slower speed; higher the ambient temperature, the lens color slightly lighter, slightly darker and vice versa. With advances in manufacturing technology, discoloration rate of photochromic Fake Oakleys Gascan Sunglasses Cheap for Sale lenses, especially fading rate has been improved so much depth to the color temperature of the interference is also getting smaller and smaller.

Weak sunlight, cloudy and no need to wear Tiffany and Co Key Necklace Jewelry Outlet sunglasses indoors. Some people do not. Even in the evening and also wearing sunglasses while watching movies, television, this will inevitably increase the burden of eye, caused by eye muscle dying with fatigue, decreased Visual acuity, vision blurred, severe symptoms such as lightheadedness dazzles.

Fake Oakleys Frogskins Sunglasses Cheap for Sale snow goggles have two narrow chisel chips, Eskimos to prevent snow blindness.

Snow mirror to the present has grown from the original simple functions, evolved to almost perfect. Initially only to prevent snow blindness, and later joined the polarized to prevent glare technology, as well as UV radiation, and so on. The snow mirror itself is also increasingly improved architecture, for example, now have anti-fog lens coating, anti-scratch, anti-shock, and many other features, the number of lenses have now evolved into the original single or a double.
Now be introduced on the snow mirror itself two most important parts: the lenses and frames

First, from the point of view of the Cheap Ray Bans Wayfarer Sunglasses Outlet Sale lens shape, divided into cylindrical lens and a spherical mirror. Spherical mirror as compared to the advantages of cylindrical lens:

a) vision, this design is more ergonomic, reducing the interference the frame.

b) a larger space, refers to the interior space. Spherical outstanding, from the human eye lens to increase. Air and eye vents hot smoke coming in, there is sufficient space cycle, fogging is not easy.
.
c) spherical lens closer to eye shape, what angle the line of sight can be maintained when the vertical eye movements, reduced parallax, Tiffany and Co Key Necklace Jewelry Outlet see objects not easily deformed.

d) impact resistance and resistance to deformation mirror ball better.

e) more beautiful, cooler, more energetic.

Second, select the frame, to focus on soft, and the design of the ventilation holes. The vents are generally adjustable mirror snow and not adjustable.

Third, the box has a thin sponge, make snow mirror more closely attached to the head. Cheap Mac Cosmetics Makeup wholesale Outlet Mirror with more emphasis on width, flexibility, length and hanging mouth texture.

Myopia metal Fake Oakleys Frogskins Sunglasses Cheap for Sale frame looks slim, work better, and the accompanying plain resin lens connection is more complex, you can refer to the details of the picture, I do not know the specific glasses are trouble. And connecting the main frame, and within the framework of the same plastic.

With the effect of the metal frame and the frame myopia, compared with plastic within the framework of the body lines and a metal frame within the framework of a perfect fit, with the seamless. But the pleasing impression behind, I have a huge question: Even gold-plated diamond, but as a framework within myopia, after hiding in the gray sunglasses, in addition to entertain themselves, for enhancing the appearance of no help in plastic inside Under the premise of the framework has been completely meet the needs of its positioning significance? Unless this section sunglasses glasses can be removed, so that with the myopia Tiffany and Co Key Necklace Jewelry Outlet glasses frame can be used as general use. But I think hard, also failed to move the sunglasses a dime, although careful observation of the lens is stuck in the frame above. The manual does not explain this, I is not free to comment, I hope Agents can give an explanation. Also need to note is that this metal frame handling difficult, the card is dead, especially when the demolition, I finally removed, the cost is slightly deformed from frame has the nose bridge.

Glasses and optical center correction sheet metal frame myopia are placed in their original packaging in a furry accessory storage bag, and I did not use the correct piece with the lens at the time, because I saw the glasses shop staff is also using the same Tools glasses. Positive and negative sides of the instructions in English and a brief introduction to the material and Guidebooks, very simple.

Shortly after receiving the Cheap Mac Cosmetics Makeup wholesale Outlet glasses to the plastic frame with a myopic lens, as an everyday shopping, car use, and then went to find a weekend trip short, which are at home, in the car and in the Peak, in the hope of different scenarios, give us a intuitive feeling worn appearance. Model really ugly point, but they cannot cover the face shot glasses pictures ah, you improvise.

I head circumference 60cm above normal face, from the picture point of view, I personally feel this section for glasses or face a little bit bigger. Tightness glasses fit, long wear without much discomfort, nose pads actually used when there is no light looked so hard, Cheap Ray Bans Wayfarer Sunglasses Outlet Sale more comfortable, just started a little while yet familiar folder, and later learned to adjust the angle of the nose pads after enough.
