The thinner work values inventory and lighter lenses with high refractive index (nd) of high quality materials affect the glasses in a very important way. Thin lenses are attractive, while not large. Lightweight glasses are comfortable, while not heavy. So it's no surprise that most of us want the most thin and light lenses. This applies in particular to those whose diopters are higher. Most consumers are myopic glasses. Lens spelling work values inventory correction of myopia with thicker edges and thinner in the middle. The higher the values that are thicker edges. Most of today's fashion work values inventory frames are made of plastic or metal with a thin circle than the edges of the lens itself. Also, the popular rimless frames (frames without kazhila intended a o that the edges of the lenses are fully covered. In both cases, the edges of the lens are very visible. These thick edges can distract from the appearance of your glasses and do not look well. How are lenses with high index of the standard
Spectacle lenses are able to correct vision because they refract work values inventory light passing through the lens. Amount of refracted light, which is necessary to ensure good vision is defined by prescription for glasses provided by your eye doctor. Weak eyes, the value of the recipe work values inventory is higher, and the lens must refract light more to provide clear vision. Prescriptions work values inventory for nearsighted people begin with a minus sign (-). If your prescription is -5.00 diopters for example, you are very nearsighted and need a stronger lens than any prescription -2.00 example. work values inventory To refract light, higher minus lenses have thicker edges of the lower values of minus lenses. Myopia can deteriorate with time, which means the edges of the lenses will become thicker with each alteration to the recipe. Fortunately, chemists have created a number of new lenses made of organic materials that refraction of light is more effective than traditional organic lenses used in eyeglasses. This implies the use of less material for lenses with a high refractive index for the correction of myopia same values. Advantages of lenses with high index
Thin. Due to the ability to bend more effective for myopia lenses made from high quality material with a high index have thinner work values inventory edges of the same, made by conventional organic material having the same value as a prescription. Light. The thin edges require less material, which reduces the total weight of the lenses. Organic lenses made of high index are lighter than the same traditional organic lenses, so they are more comfortable to wear. Mineral lenses with high index are also thin edges, but the mineral material is heavier in general, so it is not so much difference work values inventory in them, as in organic lenses. Light lenses are more useful in prescriptions for farsightedness, which can make standard lenses severe. The lens with the highest index also have an aspherical design, making them flat and reduces the enlargement work values inventory of the eye, causing the standard lens in diopters for high hyperopia. The choice of lenses with high index
Different versions of thin and light with high index lenses are classified by how well refract light. The ability to diffract light is controlled work values inventory by the "index of refraction" .This is the ratio between the speed of light as it travels through the air and the speed of light, when it passes through a transparent material. If a material passes more light speed slows down, which is good. So the higher refractive index of the material have thinned work values inventory lenses.
High index lenses can be much thinner and lighter, even with high diopter. The three main types of lenses are: without correction (eg sunglasses) in hyperopia and myopia, nd
