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.
