The arrival of summer, everything seems to be enveloped by the glaring light of day, for outside of Alice for a long time, this is not only uncomfortable, more prejudice to see the sights. If you do some activities such as rafting, sand car, bicycle, then you has to put on a pair of sports Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses.
But how to choose suitable outdoor Sun glasses, a lot of people are not very clear, often by feel, follow the crowd. Reporters in consultation with professionals, combined with information on the professional sites, you can give some references.
Best anti UVA and UVB
From a professional point of view, in the selection of sports glasses, when we should focus on the lens function. Because different lenses filter the light differently, which can be suited to different environment. Dark than light lenses are better, and can effectively isolate ultraviolet light with increased UV index. For example, purple lenses can reduce the visible eye level does not affect vision clarity. Cycling eyewear lenses can be purple, and is suitable for long wear. Grey lens that offers the best color perception, experts recommend type. And the yellow lenses, can enhance contrast fog days, it is recommended that when driving, do not wear. Yellow green and purple gradient lenses can effectively filter the blue light of the gilded mercury, enhance the contrast of the sky and the ground, so Golf Tiffany and Co Outlet glasses with yellow-green and purple lenses, making ball more defined in the view. Every day the Sun is constantly emitting ultraviolet, visible light, infra-red, the three light, if there is no appropriate eyewear protection, each of which would inflict serious damage to the eyes and affect. Choose a suitable exercise requires sunglasses, color is very important. In addition, best buy anti UVA and UVB radiation-proof glasses.
On the selection of sports glasses, everyone is different strokes for different folks, different faces on the frames of different shapes have different requirements. Here's a simple and easy to remember tips, namely, the principle of complementarity formula--round face shape, square face ellipse selection. Specific operation is equipped with a square face large Aviator-style glasses (commonly known as "blue"), can modify the prominent jaw lines; round face frame slightly coarse blending, lens color is cool, dark glasses and shrinking face Visual effects. Long face you should choose oval or curved lenses, slender proportions, gives a sense of unity on the vision, cat eye frames are the best choice; the joker is face, cheap oakleys sunglasses for all shapes; small faces fine for frames or rimless glasses, choose the elegant glass may have unexpected results.
Frame selection should be soft and elastic, resistant to impact, security face injury during exercise. Veneer design makes eyes were glued to the frame edge of the frame to prevent fast moving winds in stimulation of the eyes.
"Glasses" should be selected prescription sunglasses
Near-sighted's Alice and outdoor enthusiasts will of course have to choose their own degrees of myopia eyes sport spectacles, they not only have the General performance of glasses, but also used PC materials can impact resistant surface, such myopia friends can also enjoy the fun outdoor sports.
For more advanced climbers, even heat, snow remained on the mountain is very easy to damage the eyes to ultraviolet light, reflected light of 4000 meters above the snow line well over the sea with the naked eye is very easy to damage the retina, causing "snow blindness" caused untold suffering, sunglasses can reduce this damage. Sometimes, people can be fooled by cloudy weather, because UV rays can penetrate clouds, bright lights can cause headaches, and outdoor sports glasses can exceed 95% filter effects.
Used outdoor glasses, try to take some protective measures to prolong the service life. For example, avoid contact with perfumes, insecticides, chemical goods, to avoid chemical corrosion for lenses, frames, and better protect your glasses; please send your sports glasses wipe after use, keep mount glasses bags, not placed in the hard or sharp objects, so as not to scratch your lenses or topcoat.

Colored contact Tiffany and Co Outlet lenses has swept the world, become irresistible fashion trend, consumer awareness of the lenses remain blind. In view of this, Johnson School of Optometry Ms Ophthalmology Dr Tien Hsin made it clear that matching the three common mistakes of color contact lenses, called for consumers to match the quality of color contact lenses.
Security error: wear eye there is no foreign body sensation; these expert reviews of color contact lenses are safe: "this is the most common mistakes consumers! According to the relevant Central Department entitled the report on color contact lenses safety, even though eye damage at the point of needing treatment or stop wearing contact lenses, and eye pain and other symptoms may not occur? When advised consumers to buy color Cheap Mac Cosmetics Makeup wholesale Outlet contact lenses, selecting lenses really wrapped sandwich technology of pigments, pay attention to moisture, oxygen permeability, UV and other health standards.
Security myth: colored contact lenses belong to the cosmetics category, feel free to purchase. Experts commented: "not cosmetic color contact lenses! food and drug supervision departments have already clearly colored contact lenses would be a class III medical device, the wearer should have relevant certificate store to buy big brands, normal color contact lenses.
Security myth three: color contact lenses on the market using pigmented coating technology, so are health and safety does not hurt the eyes of experts commented: "not all color contact lenses Fake Oakleys Frogskins Sunglasses Cheap for Sale are safe and not hurt the eyes. Both at home and abroad have started to conduct a number of experiments for color contact lenses, identifying the quality and safety of all brands of lenses.
United States well-known magazine published an article was tested 7 different lenses on the market distribution of pigment, showed some of the color pigment is exposed at the surface. Ann Johnson used a real sandwich technology, color pigments of caught in the middle of the lens material, found no pigment on the surface. Japan's report also noted that related departments, tests confirmed that some brands claim that their product is pigment coating technology, but actually failed to do so. United Kingdom Association has released, titled report of the microbial adhesion of colored contact lenses, pointed out that the color on the surface of pigments leading to significantly higher bacterial adhesion. confirmed Johnson as the beautiful "sandwich technique" will be true isolation of pigment in the Middle cheap oakleys lens, can be done with transparency is difficult to stick like throwing bacteria.
Children nearsighted parents first thought is to take their children to Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, but they often do not understand that professional medical optometry professional national accreditation of the optometrist or pediatric ophthalmologist provides technical support for optometry and mirror of medicine, and all this is the most common optical shop is far from complete. Senior ophthalmologist points out that prepared glasses for their children must have to be a professional comprehensive optometric medicine, only in this way can the child's eyes, vision development to provide maximum escort. Children nearsighted parents first thought is to take their children to glasses, but they often do not understand that professional medical optometry professional national accreditation of the optometrist or pediatric ophthalmologist provides technical support for optometry and mirror of medicine, and all this is the most common optical shop is far from complete. First, medical diagnosis: first of all, medical optometric needs to have a professional Tiffany and Co Necklace Jewelry Outlet Store national accreditation of the optometrist or pediatric ophthalmologist provide technical support. Child appears blurred vision, parents should take their children to the hospital in time, specialized pediatric ophthalmologist or optometrist for a full medical diagnosis, determine whether the child is true myopia or myopia is pseudo myopia and symptomatic treatment. Second, the medical Optometry: then, ophthalmologist or optometrist optometry according to the provisions. Through detailed medical optometry diagnosis, determine whether the nature of myopia, adjusting and binocular vision problems abnormal collection. Through the analysis of Visual function and different diagnoses, refractive correction of personalized children's science programmer, open medicine dispensing prescriptions. Third, the mirror of Medicine: Finally, the mirror divisions actually check the data given by the optometrist for medicine making mirrors. The same glasses prescription, mirror master and mirror devices are not the same level of professionalism, prescribed Cheap Mac Cosmetics Makeup wholesale Outlet glasses effect can vary widely, so select specialty hospital medicine mirror making is very important.
Contact lens wearing comfort Tiffany and Co Necklace Jewelry Outlet Store, vision and vision of the true nature of the unique advantage of being more and more patients with refractive errors in the favorite. However, after some patients wearing contact lenses, simply dismissed the squeeze out glasses frame, while ignoring the advantages of glasses with contact lenses can not be replaced, this is not desirable, the best way to wear should be: contact lenses and glasses worn interchangeably.
First of all, alternately wearing contact lens complications can be reduced relatively extended the life of the lens.
Because contacts directly with the important refractive error of the eye tissue cornea, corneal need 80% oxygen directly from the air, so after wearing contact lenses, reduced oxygen uptake to varying degrees; interferes with the normal excretion of metabolic activity of the cornea and tear, so grabbing defenses down, and may induce some eye diseases.
Especially the timeout in patients wearing contact lenses, Cheap Mac Cosmetics Makeup wholesale Outlet eyeglasses and long mechanical friction on the surface of the cornea, conjunctiva and cornea lens cover under prolonged anoxia, will cause corneal epithelial damage, increased secretions, many are broken down, metabolism of proteins attached to the lens. Long time not only eye due to corneal oxygen at long, but also because the lenses were not cleaned in time to influence the service life. Therefore, contact lenses have on health and day care requirements.
For example: no timeout to wear, do not stay in polluted air environments; cleaning and care the lenses to complete these details in a timely manner and if not careful, it will become a potential cause of eye disease and genes affecting the life of the lens. Frame mirror overcomes the shortcomings of contact lenses, such as picking nursing is simple, easy to wear, not under the influence of environmental factors (as opposed to sand), and because of their wear outside the eye, does not interfere with the normal metabolism of the eye, easy to throw an eye. Therefore, if we can choose to wear in different situations, so that their strengths into full play their respective advantages, making the eyes under optimum conditions, can get a better visual.
Second, alternating wear contact lenses can be improved after stopping wearing comfort of wear frame glasses.
Because of the Fake Oakleys Frogskins Sunglasses Cheap for Sale contact lens Center thickness of only 0.02mm~0.2mm, curvature changes slightly, and directly over the cornea, therefore, framed mirrors are usually not limited vision, Prism and dispersion and aberration effects. So, if wearing contact lenses, abandoned frame mirrors. In the event of a need to stop wearing contact lenses when you wear glasses, (especially Anisometropia in large and highly refractive) will narrow the view of these aberrations, dispersion, and Prism effect counter and a series of sudden changes within a short time and makes it difficult for patients to adapt.
Optical knowledge vision killers, playing computer games topped the list. We study, work, live, play, and almost always without computer. This is a close-up of the luminous body. Computers as the most frequent tools we close eye, was also brought to the eye's largest source of fatigue. Surveys show that 82. 4% computer users suffering from computer vision syndrome. Performance for dry eye pain, vision loss, incidental, such as dizziness, neck acid. cheap oakleys Jiang Yukun optometrist optician optometric Center reminded members of the public lying written work, poor eye health habits, genetics of high myopia, unexpected lesions such as medicine, are also factors contributing to myopia, cannot be ignored.

Glasses when sales staff will ask you to choose which Fake Oakleys Frogskins Sunglasses Cheap for Sale lens is non-spherical mirror or spherical mirror; and will come up with two kinds of lenses than let you see results, and then tell you aspheric compare welcome by everyone, then aspheric What are the advantages make it so popular? how do we identify aspherical it?
Full understanding of the advantages and aspherical lens identification methods
First, what is non-spherical mirror
The so-called non-spherical lens, refers to the front surface of the lens (ordinary aspherical lens) use of non-spherical design, which means that the curvature of the lens is not a fixed value. Such lenses will watch over conventional spherical lens outer thinner, that at the same luminosity and refractive index aspherical lens will thin more than 10%; while the vision presented by the lens will be greater.
Second, the advantage of aspheric
1 aspherical lens surface with high-tech design, by the scope of the center and the edge of the mirror and the light entering the eye are the same focal length, which makes the imaging light path lens acceptable range is large, light entering the eye more, Cheap Mac Cosmetics Makeup wholesale Outlet visual good effect.
2 aspherical lens center and periphery close to the same degree, to see objects no aberration.
3 conventional spherical lens above the center of prism degrees around; rather than spherical lenses are precision grinding, high temperature softening, leveling, surrounding the center of prism degree closer. For the same refractive index lenses, aspherical mirror thinner than the ball 17 percent, 10 percent lighter.
4, aspheric lens surface is flat, spherical lenses than ordinary wear to a more beautiful, comfortable and has become a fashion of many white-collar consumers.
5, can reduce or eliminate the nasty astigmatism (astigmatism), that is, away from the scene with the optical center and distortion, which is the Achilles heel of the spherical shape of the lens, this phenomenon is a positive change in the arc through aspheric urination shaped surface to overcome the road, be able to do with the eye away from the central part of the lens, and is still very clear, as the object of effect.
Three aspherical lens identification methods
1 use focimeter identification. Spherical Tiffany and Co Outlet lens vertex degree compared with the edge, the edge is less than negative vertex degree; positive vertex degree is less than or close to the edge. Rather than spherical lenses vertex compared with the edge of the degree, whether positive or negative film, spherical degree closer to the lower edge, and the closer to the higher degree cylinder edge.
2 naked eye observation. The same material, the same degree of spherical compared with non-spherical, aspherical lens flatter, thinner, depending on the material more realistic, more natural and comfortable. If the front of the tube watching the shape of the lens coating is generally spherical lens reflex tube relatively straight (except for high-diopter lens); rather than spherical lens surface due to various parts of different curvature, the curvature of the larger tube shape.
3 using the mirror of the table to identify. Same spherical curvature of the lens surface, rather than spherical lens surface curvature also vary due to the different parts. By measuring the results mirror of the table is very easy to identify.
Four aspherical lenses for the crowd
Thin aspherical lens, mirror edge difference can be corrected, with the naked eye to see objects is almost the same, more health care than spherical lenses. Suitable for a high number of persons, high astigmatism, contact lenses and glasses wearers and first alternate wearing Tiffany and Co Necklace Jewelry Outlet Store glasses and wearing large frame glasses. But not for those who are particularly sensitive to the eyes of those who require high vision, strabismus.
