There are many types of cheap Oakleys glasses. Usually, we are based on their own needs to choose their own glasses.
For indoor workers, the basic work in front of the computer, so the main radiation, so choose a professional radiation protection glasses with the role of protecting the eyes. For some myopia, you can choose to protect the blue lens anti-radiation lens to reduce the radiation caused by the damage to the eyes.
How to choose anti-radiation anti-fatigue fake Oakleys glasses; anti-radiation anti-fatigue is mainly used to defend the country’s strong ultraviolet and computer, mobile phones, LCD screen radiation and other eye damage, our eyes are our “window of the soul” a very fragile Organ, particularly sensitive to these radiation. In order to prevent their own eyes from the fatigue caused by these radiation, how can we choose anti-radiation anti-fatigue glasses.
First of all, is the choice of the type of lens: radiation foakleys glasses have two lenses, one is coated lenses, one is the synthesis of the lens. Surface coating lens is coated with a layer of reflective film on the surface of the lens, the radiation can reflect and offset; it has the advantage of simple process, low cost, the disadvantage is relatively low radiation performance, can only prevent 30-50%, not Durable, easy to wipe the surface coating layer, this anti-radiation glasses market retail price is generally 100-200 yuan. The synthetic lens is a multilayer derived electromagnetic, reflective lens layer vacuum synthesis. Its advantages are durable, good light transmission, impact resistance, anti-radiation rate as high as 99.9%, the disadvantage is the complexity of the process, high cost. Market retail prices are generally higher than 300 yuan, or even thousands of dollars. The following is the use of vacuum synthesis lens before and after the effect of contrast.
Second, the choice of the quality of the lens: This should take into account the lens light transmittance, the thickness of the lens, the lens weight and lens hardness, in general, with multi-layer anti-reflective film of optical knockoff Oakleys lenses, colorless optical lenses And non-spherical ultra-thin optical glasses light transmittance is better, glass lenses heavier than resin lenses. Glass lenses are higher in hardness than resin lenses and are more wear resistant. The resin lens than the glass lens strength, impact resistance is not fragile, the specific choice of what, depending on the needs of each person to decide.
Finally, from the feeling of wearing to choose: the first hand holding a frame, placed in front of 25 to 30 cm, the lens convex outward, slowly shaking up and down, from the lens to observe distant objects. See if there is a wave of irregular deformation or beating phenomenon, if any, known as “Huo Guang”, that the lens surface uneven. Since the radiation-resistant lenses of replica Oakleys have the presence of a radiation-proof layer, when we wear – especially the first time we wear on the computer again, it will obviously feel visually clear and very natural. Usually the kind of see the display particularly glare and a slight beating will disappear completely. The better the quality of the lens, this effect will be more obvious.
