When consumers buy sunglasses, be sure to pay attention to where

Different groups of people, according to different preferences and different uses to choose the sunglasses, but the most fundamental thing is to protect the wearer from safety and visual basic principle by the injury. Reduce the glare stimulus, visual clarity without distortion, anti-UV, no distortion of color recognition, accurate identification of traffic signals, should be the basic function of sunglasses. If these features are flawed, at worst not achieve sunglasses, and the heavily will produce dizziness, eye soreness and other symptoms of conscious not meet, and sometimes slow to react, argue, as the object color illusion and walking, and trigger symptoms of inequality traffic accidents and so on. So select the style sunglasses can not just focus on the neglect of its intrinsic quality. High-quality Polaroid TAC polarized lenses, polarized lenses protect your eyes from reflected light that people harm, can enhance the visual contrast outdoors, especially while driving, polarized lenses can be reduced glare, stray light.
Summer is the world's sunglasses, fashion, beauty, radiation protection, these features make it more like wearing sunglasses, but experts point out that, when selected mens sunglasses should take care not only concerned with style, but ignored their quality sunglasses. The following four kinds of failure do not wear sunglasses:
1, anti-ultraviolet unworthy of the name of the sunglasses. Good sunglasses polarized lenses can block 99% UV. Functional difference between wearing UV sunglasses, his eyes as if seen in the darkroom thing, then the pupil will become a large, residual UV launched into the eye but rather large, so that hurt the eyes. 2, perspective rate of unqualified sunglasses. Wear, will have traffic signals identify obstacles easily cause traffic accidents. 3, unlabeled categories logo sunglasses. Sunglasses are generally divided into three categories, namely for the shade of the sun mirror, light mirror for decoration and for anti-plane radiation waterproof snow blindness or special glasses. 4, against the performance does not meet the requirements of the sunglasses. By external shocks in the lens easily broken, debris will form a lethal injury to the eye.
And consumers in choosing sunglasses, you must pay attention to:
1, we must first know the purpose of choosing sunglasses
From the above description of several types of sunglasses, we know that there are different types of sunglasses for different occasions and people. First of all we have to buy sunglasses, make sure your purchase is intended for shade, or for decorative role play with costumes? In addition to whether the UV shade outside the functional requirements? The safety performance of the lens with or without special requirements? Only clear these aims, combined with style and wear the actual results in my face, to purchase a suitable sunglasses.
2, to learn to read the Product Identification
Not all sunglasses have a UV features a standard to meet the basic requirements of sunglasses, can only block the light at the same time no more UV through. If a pair of sunglasses can block light and can not block the same amount of ultraviolet light on the wearer, the TradeTang sunglasses will be accepted no more than the UV (wearing sunglasses, will reduce the flux into the human eye, resulting in wearers pupil increase). Sales counter at the store sunglasses, the lenses, the tag or packaging are generally clear uv380, uv400 and similar signs, as in the clothes have the same fabric content label, consumers must purchase closer look.
3, the intrinsic quality of the lens should be to identify the basic skills
(1) Women's Sunglasses lenses degree should meet the requirements of the plain glass lens, and should not affect the vision of the optical flaw. Simple identification method can be placed in front of sunglasses, observe distant targets through a lens, such as window frames or door frames, etc., and then glasses up and down before and after the move, targets should not sway and wave-shaped deformation.
(2) the color of the lens can not be partial, so that the environment should be the color distortion, sharp edges of objects with effective identification of the capacity of different color lights. The choice of lens color depth, as required by the activities of the place may be, for different light sources and situations, will affect the color of the lens shading effect. For sunglasses can effectively block the intense summer light, the color of glasses due to sufficient depth, but those who ride or drive, do not choose too dark lenses.
Just follow the above statement is done, you will choose a good satisfactory sunglasses.

How to choose sunglasses

As the weather continued to heat up, summer schedule from, the sun radiates heat into the earth sprinkled selfless, strong light stab the eyes narrowed to only half of Pool and a half, "Oh! If there is like a vice sunglasses, but also 'Cool' another shade line. " So fashionable people in a variety of sunglasses to interpret the trend this summer. Then tell us about how we choose to wear sunglasses to prevent eye damage.
Style fashion wear glasses, does bring new look, the effect of finishing touch, but do not overlook another important function of glasses - to protect their eyesight from the sun's ultraviolet and infrared damage people's eyes in the kind of environment, maintain normal visual function.
Here also tell you that not all of the mens sunglasses are suitable for everyone to wear. Not all of the sunglasses can protect the eyes function. So, how to choose according to their own sunglasses it right? Let us first look at the functions and appropriate sunglasses crowd it!
First, sunglasses it is to have the anti-ultraviolet and infrared, as well as to filter light of short wavelength light (eg blue), because these light damage to the eyes bigger. If by these eyes, long light exposure. Suffering from cataracts and macular degeneration, the possibility is high. Also, by the ultraviolet eyes of the strong stimulation, will suffer from a kind of damage to corneal epithelial disease - called the "electric ophthalmia." So wear glasses with these features can effectively protect the eyes.
Second, sunglasses should have "visible" in the transmission. To control the intensity of external light enters the eye, according to the standard production of glasses (usually should be controlled at 15% - 30%). If a pair of glasses, "visible" transmittance greater than 30%, the eyes of "dark adaptation" capability could not be adequately protected. Work long hours under the sun personnel should wear "visible" transmittance of 15% or less, old people wearing "visible" transmission of less than 10% of the sunglasses will affect normal vision. Pilot should wear "visible" transmittance 8%, so as not to affect safety. Glasses of the "visible" in transmittance is not able to distinguish with the naked eye, the light can be accurately detected spectrometer.
Third, different colors Women's Sunglasses, with different eyes color vision disturbance, we try to choose the eye color of color vision disturbances small. Here are several different visual effects color sunglasses.
1. Ink and brown lenses: the general increase in sunlight contrast ratio.
2. Green lenses: reduce "visible light" into the eye level.
3. Grey lenses: to provide the best perception of color perception.
4. Yellow lenses: enhancing contrast in fog, but the feeling of confusion caused by traffic lights.
5. Orange lenses: In the case of low illumination to provide maximum contrast to the eye, and effective filtering blue light.
6. Pink lenses: for indoor environments, such as working under fluorescent lights used, if AR is better.
Fourth, the staff often engage in outdoor sports should wear sunglasses strong impact resistance, such as pc lens (a lens made of fiber materials). Officers operating in the water (the crew) should have anti-reflective film or polarizing Pei Daijia functional sunglasses to reduce glare effects on the eyes. There is also a function with color sunglasses, sunglasses for this frequent out-home and outdoor staff. With the development of technology, now mostly resin lens glasses, this lens has the advantage of lighter, thinner and more effective. Play better protect visual function.
5, glaucoma patients can not wear sunglasses shade of ink (including the color is rather deep and glasses), because glaucoma patients (in particular, angle-closure glaucoma) should be avoided whenever possible in the dark room work, because the pupil will be in the dark environment and dispersed Crystal diaphragm narrow, affecting the normal aqueous circulation, increased intraocular pressure. These determine, glaucoma patients wearing sunglasses, you can have a similar effect darkroom so dilated pupils, may cause eye swelling, discomfort, and even elevation of intraocular pressure. Therefore, patients suffering from glaucoma is best not to wear TradeTang sunglasses.

High Speed Dome prospects

With the "Green City" ever-expanding, high-speed ball faster and faster development of the camera, with its unique features is its 360 ° rotation function, can Jiance to all regional areas; with easy installation, simplifying the wiring and management process ; integrated, high level of intelligent high speed dome camera features to become the darling of the field monitor. A few years ago, high-speed global market is mainly imported brands command the world. Integrates multiple high-speed ball is part of the equipment, the price usually increases than the traditional PTZ camera, the shield must be high. Therefore, high-speed ball in the user's mind is the high end and expensive, so little to attract the buyers. Today, the domestic high-speed ball technology, the quality is relatively mature. In the price, whether it be domestic or imported products, are adjusted annually, imports high-speed ball from year 5 to 6 per million price reduction to 1 to 2 million; domestic high-speed ball from low to high price allocation Each area is about 3000 ~ 7000 per month. Most do not have high-speed ball past the place, such as residential, roads, etc., have begun to use more and more. It can be said now could be seen in various places high ball figure, such as urban surveillance, stadiums, ports, metro, campus, building, hotel, etc.. Application of these areas were to some extent, increased market capacity for high-speed ball.
In recent years the majority of the industry reflects the country "safe city" construction is very active high-speed global markets one of the most important factor. Because in the outdoor urban monitoring projects, integrated cameras and camcorders are the leading high-speed ball, especially in city traffic, high-speed ball is widely promoting the use of front-end equipment. According to industry estimates, from the makers of several major movements of foreign giants to purchase the number of integrated view of movement, the current annual demand for high-speed ball is about 6 to 7 million units, while with the "Green City" in the implementation of this A number will further increase. The reason why high-speed ball control in popularity in the city, with its own characteristics are inseparable. If the intersection control, the speed the ball can be 360 ° rotation, no blind angle, the intersection of the four directions can be "balanced" to, and track, respond to events quickly. When someone runs a red light, the speed the ball will automatically rotate to quickly monitor the intersection in all directions. If an ordinary camera, you need to rotate people. In addition, in some situations need to repeat the monitoring action, the high-speed ball preset position can meet the requirements of the monitor functions. In view of these advantages of high speed ball in the ongoing "Green City" building large projects, some will use hundreds or even thousands of ball machine. Addison security engineers that the TradeTang high-speed ball front-end equipment in urban monitoring applications account for about 1 / 4. The current construction of 21 pilot cities is already used in 10 to 20 million high-speed ball, with the other cities have started monitoring the project, use will increase. The total application from the current situation, as "Green City" is still in the initial construction phase, high-speed ball not really large area, high-volume applications. Such as Shenzhen, Guangzhou and Shanghai, has just opened the current high-speed ball, not to large-scale application period. "Green City" building capacity for high-speed growth of global markets, but also increased market awareness of the high-speed ball and the ball manufacturers to bring high-speed business. "Green City" building is the large-scale government-led projects, the high-speed ball manufacturers will not miss these items. The Security 2005 exhibition in Shenzhen, you can definitely feel that more and more competitors have joined the battle for this market into.
Speed ball is a built-in integrated camera, PTZ, the composition of the monitoring system decoder. Integrated camcorder accessories in matching high-speed ball directly affect the image quality. Currently, the overwhelming majority of foreign companies to purchase one vendor movement. Decision performance PTZ control hardware and software elements. Software has a control circuit, sub-micro-step and the operation of error correction algorithms, hardware with the motor. As the high-speed ball, down, left and right rotation are driven by two motors, motor speed will directly affect the performance of the ball's speed, position and stationary. Therefore, by controlling the number of pulses can precisely control the angle of head rotation and accurate positioning. Stepper motor control in the way, now most manufacturers are using high-speed ball-chip microprocessor to the movement direction of the stepper motor and stepper control the number of steps. With the privacy block, self-learning features such as high-speed ball trajectory in the popularity of a single chip has been found difficult to meet the increasingly feature-rich, high-speed ball, you must use three or more intelligent control, whereas use of DSP as the processor will also be a direction.
The development of high speed dome camera in the initial stage, people buy products, the main consideration of its general operating functions, such as the camera's focal length range of pixels, horizontal resolution, signal to noise ratio, adjusting shutter mode, White Balance Auto Tracking mode, backlight compensation and the ability to automatically switch illumination; Secondly, head for head, to consider the horizontal and vertical angle of continuous operation, speed adjustment range, including the rapid reaction capacity, high reliability and life expectancy, low speed movement the stability of the image is jitter and other factors; the preset point on the ball machine storage capacity, mainly to consider the absolute head position, zoom position memory location precision. However, as the popularity of high-speed ball-type camera, the user awareness of the rising and people on special occasions, Yun Yong and other comprehensive factors considered, high-speed ball camera Gongneng Ye constantly be updated and Wan Shan. If the ball has added a lot of high-speed multi-alarm input, telephoto, as the control, the system automatically learning and other functions.

Succinct The men, full of ancient and modern taste of the beautiful ladies, with new fabric textile products, is the main theme of the 19th century style clothing.
Each time the dramatic social changes will bring significant to women's styles change .19 century has been a "popular Century", here refers primarily to the ladies, and, as the 19th century also called "style imitation of the Century", as Women's changing almost periodically in accordance with the order appears to reproduce the style of the past.
(A) of the impact of women's classic style
Napoleonic era, Maternity Clothing on the basic shape is characterized by high stress high waist, slim skirt, short Puff sleeve Honeydew shape. Square neckline was very large, very low.

Digital cameras and proper maintenance techniques

1, digital camera battery types used
Currently, digital camera battery types can be used include alkaline batteries, nickel hydrogen batteries and lithium batteries and battery packs of four, while the choice of brands available in the market is numerous, the brand manufacturers often will be to their own own-brand digital camera battery configuration. Let's look at several characteristics of the battery.
Alkaline battery composition contains sodium hydroxide (Sodium Hydroxide) and KOH (Potassium Hydroxide). Because it has high energy output and the use of the advantages of a long time, so often used in radio, MP3/CD ,, camera and flash. However, after a period of use after discharge, alkaline battery voltage drop, resulting in a new digital camera on the actual usage time is less than nickel-metal hydride batteries and lithium long.
Currently on the market battery, made in China SUNQS Shengqi Shi, Japan, Olympus and Toshiba have produced a good performance, although one-time investment is large nickel-metal hydride batteries, but the long-term use down the cost is very high, The regular shooting of the players, should at least configure the two sets of NiMH batteries.
Second, experience in the use of digital camera battery
Digital Cameras ,the main problem is that battery charging, the lithium-ion batteries are generally used with a special charger to charge matching, effectiveness and safety of charging more secure. The rechargeable NiMH batteries need to note the following:
1, charging a reasonable choice. Under normal circumstances, the proposed options to charge the battery slow charge mode, it can extend battery life. If you frequently use the fast charge mode charging, the battery should be given a period of time several times to maintain the nature of the slow charge. 2, the charge should pay attention to other issues. Although Ni-MH battery memory effect smaller, but still suggest that you run out of power after the charge; after each charge must be sufficient to use, often without adequate cause decreased capacity. Also in order to reduce power consumption, when the shooting should be no unnecessary use of flash and zoom operations can also reduce the LCD brightness to reduce power consumption.
In the course of what, if you encounter a group of work after the battery is fully charged camera battery alert occurs shortly phenomenon shows that the cell group that has a section in the battery performance has been bad (excluding the camera problems), Wholesale digital camera can be multimeter to measure the cell voltage and transient short-circuit current to identify the battery performance is good or bad. Usually a single fully charged battery voltage is about 1.4V, 10A current file with a multimeter measured the instantaneous short-circuit current should be between 5 ~ 8A, if a cell value has significantly departed from the same group with the difference than other batteries large, it can be sure that the battery performance has deteriorated and should be replaced.
Third, maintenance, use and maintenance of batteries
Different digital cameras and traditional cameras, digital cameras a great need for electricity. Thus, lithium and nickel-metal hydride batteries they can be reused and have greater battery power more and more digital camera users welcome. However, whether lithium or NiMH batteries, all kinds of battery use, save, have a lot to bring attention. NiMH batteries have memory effect, although the low memory effect, but this effect will reduce the battery's total capacity and the use of time. Over time, less and less stored charge, the battery will also consume faster and faster. Therefore, we should try to recharge the power all the run out. If you are using a dedicated lithium batteries, or lithium ion battery, memory effect problem is how to consider the need.
Digital Camera Accessories for everyday use in the process, we should pay attention to maintaining the integrity of the battery insulation, if they are damaged, should be transparent tape cement. Check the battery's electrodes whether there situations oxidation, mild oxidation can be wiped out, but if a serious case of TreadTang oxidation or loss should be immediately replaced with new batteries. Meanwhile, in order to avoid power loss, the need to maintain contacts at both ends of the battery and battery cover internal cleaning, if necessary, you can use a soft, clean, dry cloth and gently wipe off the battery. With a small eraser (for example, the kind of pencil head) out into the battery box in clean metal contacts, but must not use cleaning agents with the solubility of the cleaning agent.

Prospects for the digital camera market

2009 and 2015, the traditional camera will also have considerable long-term areas of expertise within a broad market, although the ultimate digital camera will be completely replaced, but they will in the long term symbiosis. Both traditional camera or digital camera, its price will decline. Digital camera users as the current is mainly business users and civil users of its markets because of price restrictions has not fully started, so the price drop is inevitable.
The future of digital camera market price and the brand will become the killer competition, the competition may undergo significant changes. Digital Camera Accessories will be for the polarization of the user groups are further sub-division, consumer-level users and the needs of professional users even more obvious differences. 2009 and the next 5 years is expected to Chinese digital camera market into the stage of stable development in 2009, sales to more than 12 million units by 2013, sales will exceed 16 million units, about 9.7% compound annual growth rate. Digital Cameras in the next few years, the digital camera market price will fall below 2,000 yuan. HD, high resolution, fashion will continue to be a consumer digital camera market, the focus of attention. Changes in product mix breeds opportunities and challenges, the digital camera market into a new round of reshuffling stage.
Meanwhile, with the popularity of digital products, digital products per capita dramatic increase in the number of digital products to become an increasingly popular service industry, has been abroad as "the most profitable of the manual work", and various types of digital camera equipment in recent years, is a meteoric rise, in every city of the few digital camera repair point, all received invoices are always overwhelmed! High returns and brand maintenance station deadly ills, TreadTang promote a professional digital camera repair shop in the birth of their appearance, much to meet the needs of the consumers.
In the history of the development of digital cameras, have filed a Sony. Sony Wholesale digital camera in August 1981 for the first time in a television camera using CCD, be used as a light directly into digital signals. Sony CCD produced each year account for 50% of the global market, which is Sony's digital camera market can be one of the reasons the crowd behind, because the core lifeline in their hands.
After the Cold War ended, military technology to market quickly changing technology. In 1995, the production of traditional film cameras and has a strong capacity Kodak (Kodak) released to the market maturity of its development of civilian consumer digital camera DC40. This is considered by many the beginning of forming the digital camera market. DC40 uses the built-in to 4MB of memory, can not use other removable storage media, its 380,000 pixel CCD support generated 756 × 504 images, compatible with Windows 3.1 and DOS. Apple (APPLE)'s QuickTake 100 also introduced in the market. Both cameras were provided to the computer's serial port connection. Therefore, prospects for the development of digital cameras is vast, full of hope.

Wedding dress selection errors

Misunderstanding 1: satin wedding dress better than Shazhi
This is a lot of brides have the misunderstanding that was more elegant satin wedding dress, wedding dress itself also appears to have more grades, and in fact this is wrong, wedding materials can really show display different temperament, but also a wedding clothing, which is used to set off people, in other words, choose satin or Sha Zhi's wedding is the bride according to the temperament, personal preferences, etc. to determine, and some relatively long atmospheric bride, or the like is very simple but elegant wedding, then choose satin Bridesmaid Dresses are more appropriate, but if the bride looks sweet, cute, lively, and then wear a satin wedding dress would look too heavy, and the wedding dress scene will appear inconsistent with the human condition, such more suitable for the bride on the wedding gauze, look lively, elegant.
