Field Glasses
More details about strong glasses
As more and more achievements are made in the field, glasses can now be designed into countless styles and satisfy wearers of different groups. At the same time, however, the ways to categorized eye wear have also multiplied and will usually confuse wearers greatly when the criteria enriched on and on. In some cases, if seen from different standard, the same eye wear can be named differently. For example, black plastic glasses can be both called black eye wear and plastic eye wear at the same time. In other cases, even seen from the same standpoint, the same glasses can also be called in different names, like both black glasses and silver glasses all refer to black silver or silver black eye wear. Therefore, the same eye wear have several names at the same time. Strong glasses, also called strong prescription glasses, are such good examples. In fact, no matter what they are called, they can benefit wearers greatly.
Strong eyeglasses, referring to eye glasses with strong prescription, are mainly suitable for wearers who have worn glasses for very long time. When people have nearsightedness and other vision errors, they need prescription glasses. That’s to say, their eyeglasses should be made with certain prescription. However, as time goes by, the elasticity of wearers’ eye muscles will decline and the power will increase. Such situation will be worsen when wearers over use their eyes. And the direct result is wearers’ eye prescription become stronger on and on. When the problems worsen, eyeglasses with strong prescription, also called strong glasses, are needed. Of course, some people’s eye prescription changes quicker than others.
From another perspective, eyeglasses are initially made from glass and such situation does not change until the emergence of plastic. In order to make sure that light can be well reflected, the glass lenses should be very thick when prescription is very strong. And the result is the eye wear is very heavy and wearers have to suffer a lot, due to the inconvenience caused by thickness and heaviness. Later, as optical technology advances greatly, some top plastic lenses are invented. Especially, there are some plastic high index lenses, specially made for people with strong prescription. These plastic lenses are very thin, but with ideal vision effects. Therefore, wearers can benefit greatly from those light weight lenses, though their prescription is very strong.
And now, strong glasses can be manufactured the same as many other regular eye wear in almost all aspects, like color, designs, weight, and so on.
