With glasses must pay attention to: can not just use the traditional optometry method, a simple refractive examination glasses thing, should use the scientific advanced American standard medical optometry and three visual function testing, in order to check out the real cause of the problem. In the American standard medical optometry, including the degree (refractive) and visual function and fundus examination, and the subdivision is a twenty-one step. Eyes to achieve visual comfort, clear and lasting, in addition to have good vision, depending on whether the normal function is an important factor; "collection" as one of the important visual function, abnormal appearance will cause visual fatigue and vision decline.

Glasses in the process, often such a situation, with the same pair of glasses to see clearly and comfortable, to see when the eye was swollen, inattention or reading and writing can not be sustained. In the glasses with the national standard under the premise of the situation that there are defects in visual function, this time to do the degree of detection is clearly not enough to do binocular vision function, the development of the corresponding visual training program.

After the first glasses to do to enhance the adjustment of the promotion and anti-back training, adjust the function to do after the set of training, pen training and Brock line training. Two weeks after the students look near discomfort disappeared, can easily learn long time. Later with the combination lens, anti-fatigue lens, six months after the review effect is very good.

In short, only to ensure that the visual function is normal, so that we have a clear, comfortable, lasting visual experience. Modern visual optics theory completely subvert the traditional glasses with the measure of the backwardness of the concept, stressing both the symptoms, the optometrist technical requirements are high!
