|Online glasses raiders|
First of all, to go to hospital or formal optometry Cheap Oakleys Frogskins Sunglasses Outlet glasses shop, free or very cheap price. Is the optical shop, not soft, finished by the way has also been equipped with sunglasses, it won't have to look down.
According to optometry's situation, some people still not suitable for glasses online, such as:
1, the eye is a very heterogeneous or defective, such as PD, 8CM; strabismus severely cross-eyed ... You should be a normal, ignore this point.
2, vision of instability, such as 200 today, after a few days on the 300, so your glasses arrived, no, you should not be so bad, please ignore this.
3, eyes a lot worse, like a 10,001 x 200
+ 4, astigmatism with myopia
5, high myopia, for example, more than 1000 degrees
3, 4, 5, mainly online opticians have no physical, with the glasses a bit difficult, and put on new glasses could not adapt to needs service. If you go to the store is not very convenient.
-Choosing lenses, I learn about optical lens is quite.
First, the brand or something please ignore, if you think branding is important to you, or go to the store.
Second, many of the tiffany and co outlet features not to be hoodwinked, UV-resistant, radiation resistance, are bragging. Hardened and coated a bit, but there's no need to spend 1-2, with one Deputy, was a better choice.
The curvature of the lens, 1.56, 1.67, or something like that, the higher the number the thinner, more expensive of course. If your degree is relatively high, super thin, still too thick you can choose non-spherical (and more expensive), this not to brag, but if 6, 700 degrees of myopia, not too necessary.
Then there is the color, lenses have silver halide, increases as the intensity of the Sun, the lens darker. Personally, I think is not too necessary, should guard against the Suns in the summer and enjoy additional clamps on the line. Certainly fresh but equipped with a pair of play is good.
Personal recommendations, curvature, 1.56, green-coated film, online opticians was traded in 501
Selected frames, it's hard
Frame look ugly, opinions differ, so it's hard to say why. But spec is worth about, it doesn't look like everyone's head, still have to think about it.
Mirrors on the leg is a set of numbers, such as 18-135, 52, identified as lens width 52MM wide leg 18MM mirror long nose 135MM, depending on your size available.
Similarly, the brand is not considered, specializes in manufacture of all brands in the world.
And finally price. Many shops frames are sent send stuff is not bad, if you don't like it, pick, in short, all the specs, and normally does not exceed 100. Merchant materials cost less than 30, the processing will take about half an hour, and also give you glasses case, cleaning the Discount Oakleys Flak Jacket Sunglasses Cheap glasses, so the price is also reasonable.

Clinically, doctors generally myopic children's Orthotics to 1.0, and even sometimes needs and habits according to the child's eye, such as child seats in front, at close range with an eye more, their myopia suitable distribution low, Dai Jing vision then the children may have amounted to less than 1.0. Therefore, children Discount Oakleys Flak Jacket Sunglasses Cheap glasses may not need vision correction to 1.0, should take into consideration their demand for daily eye, wearing comfort, and other factors.
Generally speaking, kids glasses after you wear glasses at the far and near, as it makes your eyes adjust and coordinated collection capacity, could not be easily fatigued when reading. For some children with low myopia, as up to 200 degrees, you can also consider ongoing close eye without glasses, so can be reduced to a certain extent, the eyes focused enough, there might be some delay the effects of myopia development. But at the same time taking into account specific situations such as child's binocular vision, such as children with insufficient external oblique or implicit collection, regardless of it long or short are required to wear goggles.
Children require periodic review after wearing glasses, myopia increase more, Dai Jing, poor eyesight and did not meet the needs of daily life easily with an eye; you need timely replacement of glasses.

Clinical study found that rapid growth and development of children in the 10~15 period, the myopic growth rate is faster, baby, of course, this may be related to that stage reduced heavy study load, outdoor activities, and so on.
Youths wearing OK microscopy can significantly slow the progress of myopia. Age adolescents than wearing conventional glasses, wearing OK mirrors slowing myopia development about half of those, or even some wearing 3 years later in children with only 25 degrees of myopia, a handful of kids wearing only deepened the 150 degrees of myopia after 10 years.

Children wear glasses for far closer eye; there may be a problem of insufficient focus, which would have some catalytic role for development of myopia. Thus, progressive Multifocal Lens tries to apply to children and teenagers. It works by reducing the degree of myopia when, to reduce the problem of insufficient eye focused short. Lots of studies have found that wearing progressive multi-focal lenses have a delaying effect on myopia development in some children. But wearing such glasses you need to fully take into account children wearing habits, reading and writing position, binocular vision.
