I am engaged in a hole? Optical occupation education workers, engaged in this job for nearly thirty years. In this thirty years, often there will be some glasses colleagues, neighbours and friends, to learn about the optometry, optician problems, such as how to choose glasses frame, how to choose glasses etc.. At present, the vast majority of the wearer, to understand the optometry and glasses, just by reading about Department of Ophthalmology care, love eyes eye protection of popular science books. However, this kind of book types although many, but the central problem to optometry, optician for this book is less. From colleagues, neighbors and friends often keeps asking about this situation, people who wear glasses still very want to learn this knowledge, there are a lot of glasses industry colleagues and suggestions for the majority of people who wear glasses to write such a book. Based on the above, the author will be engaged in the eye? Optical occupation education since often asked questions are summarized, and the problems related to occupation training school officials mentioned together. Based on these two issues, and pick up lens users are most closely related to the problem, it is divided into ten parts. Taking into account the readers to read this book, is likely to choose to read way, so do the corresponding design at the time of writing: if each part is a whole, and each one of these subjects are also an independent problem. Due to my limited knowledge, the book also there may be some omissions and deficiencies, hope that the majority of readers, especially glasses industry colleagues to be correct, and made valuable suggestions.
"As clear as noonday glasses" mainly introduced in the daily use of eye and with glasses in the process, we should know some refractive, optometry and correction of related knowledge, discussed the eye refractive, from a professional point of optometry, glasses frame and the glasses, contact lenses, choice, with straightaway language, explain profound theories in simple language to introduce scientific knowledge, can give the reader more intuitive understanding more image, so that the reader can use in daily life, the correct optometry, so as to realize the protection of eyesight, improving vision objective. "As clear as noonday glasses" can provide care for eye health, expected to acquire or guarantee good vision people refer to use, especially suitable for the majority of parents of children reading reference.

The eye as shown in Figure 1-1 structure of human. Simply put, the eye structure is: three layers of skin, a bowl of water, a fire burned in front of a lump of jelly, open a window, behind a small bias aside. A layer of "shell" is the outside of the outer membrane, we will call the fiber membrane. This layer is composed of two parts. One part is located in the front of the eye, called the cornea, the other part is corneal behind the larger surface area of the white sclera. The cornea is a transparent, the surface looks cornea is round, that is not the case. The cornea is a horizontal elliptical, vertical diameter should be less than the level of about 1 mm in diameter. The characteristics of corneaIn the refractive properties of the eye is significant, indicating that human existence: mild astigmatism is normal, astigmatism degree of light in the not up to 0.5DC, will be judged as no astigmatism. The next layer is a film in the eye, this layer of membrane, called the uvea. The film used to form has the very big difference. The front part of the said that as the wheel, also someone says like Falun, this part is called the iris, surrounded by the iris is called the pupil window E1. Hole. Under normal circumstances, this is the only channel 1 pupil outside light into our eyes. A ringlike structure behind the iris is a triangular form by cross-section, like the ring on the construction of the dam. The back is lined in the "shell" in the "egg shell membrane", this structure is called the choroid. The innermost layer is "egg membrane", this is the retina. This is the external object impression in our eye position, but also our subjective visual process really start position. There are two special functional region in the retina. If, in the eyes of the optical axis as the dividing line of words, by this very small area outside, is called the macular region, the regional center for a 0.2 mm sag sag, which is called the fovea. This is our only area of clear vision. We usually put the three layer of the film outside, in the eye, inner, collectively referred to as the wall of eyeball, referred to as the ball wall. The remaining part of the eye is the eye content, referred to as the eye content.
